INTRODUCTION

The California Highway Patrol (CHP) has initiated the CHP Enhanced Radio System (CHPERS)

project. This enhancement project will provide an effective and efficient radio communications

system that supports CHP’s primary mission, improves internal and external services, and

enables radio interoperability with allied agencies during joint tactical operations and emergency

incidents.

The CHP Enhanced Radio System will:

• Acquire a Consolidated Patrol Vehicle Environment (CPVE) and associated new

mobile radios.

• Replace an aging custom-designed infrastructure with new industry standard

equipment.

• Allow officers the ability to communicate at a greater distance when away from their

enforcement vehicles.

• Allow communications centers to operate their primary and secondary frequencies

independently and simultaneous from each other.

• Be capable of automatically broadcasting inbound mobile transmissions over a wide

area so that most mobile units will have the ability to monitor mobile transmissions.

• Include additional radio channels for tactical and emergency operations.

• Enable radio interoperability with other public safety agencies without impacting day-

to-day patrol operations.

• Allow all communications centers to have multiple alternate dispatch control points for

control of the fixed radio system.

• Provide radio communications at inspection and scale facilities.

This document will provide a general overview of the existing CHP radio system and will discuss

the various aspects of the CHPERS project. More detailed information regarding the existing

CHP radio system can be obtained from the Office of the State Chief Information Officer

(OCIO), Public Safety Communications Division (PSCD) (formerly the Department of General

Services, Telecommunications Division). It is assumed that the reader has a basic under-


standing of the existing CHP radio system and the State’s Capital Outlay Budget Change

Proposal process.


CALIFORNIA HIGHWAY PATROL EXISTING RADIO SYSTEM

OVERVIEW

This section is a general overview of the existing California Highway Patrol (CHP) mobile radio

system. A brief description of the various types of radio systems used by the CHP is presented;

as well as, the types of radio base stations used and how they are controlled. Additionally, brief

descriptions of CHP’s communications centers, mobile and fixed location radio equipment, and

the State microwave system are presented. It is assumed that the reader has a basic familiarity

with the existing CHP radio system.

1. General

1.1. The CHP uses two major radio systems: a Very High Frequency (VHF) lowband

system and an Ultra High Frequency (UHF) system. The lowband system is used

by CHP as its main radio communications system with its regular patrol officers.

The UHF system is used by a smaller number of CHP Protective Services Division

officers for Dignitary Protection and other previous State Police responsibilities.

The radio systems are configured as either conventional (vote steer), simulcast or

standalone.

1.2. The equipment utilized in the CHP radio system is installed via the Public Safety

Communications Division’s (PSCD) COM 207 process. This process involves

PSCD engineering and field maintenance staff. The document(s) generated via

the COM 207 process details the scope of work being performed, required

associated parts, required schematics and detailed engineering work instructions

for the field maintenance staff. Exhibit 1 is an example of a simple COM 207 work

package for Horse Mountain which involved working at a remote site location that

is not a CHP managed vault. The COM 207 process permits interagency

cooperation when radio equipment is installed at sites not under the jurisdiction of

CHP. The COM 207 process also generates and/or updates any required site

documentation.

2. Conventional Radio System

2.1. Except for the Los Angeles Communications Center (LACC), Golden Gate

Communications Center (GGCC), Inland Communications Center (CC) and Border


CC which operate simulcast radio systems, the remaining CHP communications

centers operate conventional (vote steer) radio systems.

2.2. The CHP lowband conventional radio system is a vote steer system. The vote

steer radio system consists of multiple strategically located transmitters and

receivers. Receive audio from multiple sites is analyzed and the best receive

audio (voted audio) is presented to the dispatcher. The vote steer radio system

then automatically selects (“steers”) the transmitter associated with the voted audio

to reply to the mobile. Typically only one transmitter is selected at any given time.

The vote steer radio system is set up to vote with each new reception. The system

is also designed to ensure the voter only analyzes valid transmissions from

mobiles and not idle channel noise. Reference Appendix A, Figure A1, CHP Vote

Steer Diagram.

3. Simulcast Radio System

3.1. In addition to the conventional (vote steer) radio system, CHP also utilizes the

technique of simulcast (simultaneous broadcast) transmissions. In a conventional

mode, a single transmitter is keyed at any given time. In a simulcast mode, all

transmitters on the same frequency are keyed at the same time. Simulcast

operation also requires that the transmitters be aligned to one another.

3.2. The receive portion of a simulcast system is the same as the receive portion of a

vote steer system. Receive audio from multiple sites is compared (voted) and the

best receive audio (voted audio) is routed to the dispatcher. In the Inland CC,

Border CC and GGCC simulcast systems, the voted audio is also rebroadcasted

(repeated) over the air simultaneously via all transmitters on the same frequency.

When a dispatcher replies to a mobile, the dispatcher’s traffic is also broadcast out

on all associated transmitters simultaneously at the same time.

3.3. The following CHP communications centers operate in the simulcast mode: LACC,

Inland CC (San Bernardino), Border CC (San Diego) and GGCC.

4. Standalone

CHP also utilizes radios which operate in a standalone mode. Radios configured as

standalone consist of a console controlled base station which does not operate in

conventional (vote steer) or simulcast systems. These base stations typically appear as

secondary (auxiliary) stations on the console position. Oftentimes, the radios are part of


other state and local government radio systems. Examples of other government entities

are CLEMARS, CLERS, local sheriff offices and local police departments.

5. Base Stations

5.1. General Overview.

In general terms, a base station is any piece of fixed radio equipment that allows

radio frequency (RF) communications between end users. In the CHP Lowband

Radio System, there are two typical base station configurations: local and remote.

Other configurations are used depending on operational requirements. Reference

Appendix A, Figure A2, Typical Base Station Sketch.

5.2. Local Base Stations.

Local base stations are generally used at area offices. A local base station is

comprised of a transceiver (a single transmitter and receiver unit), two auxiliary

receivers, a transmit/receive (T/R) relay, filtering equipment (intermodulation panel,

etc.), and an antenna system. A local base station is connected to the area office’s

desktop console and not to a communications center’s dispatch console. The local

base station is used by an area office to communicate car-to-car (transmit and

receive using the “C” channel) on the office’s primary and Blue (BLU) frequencies

and to listen to the primary “S” channel.

5.3. Remote Base Stations.

Remote base stations are generally located at remote sites. A remote base station

is comprised of a transceiver (a single transmitter and receiver unit), one auxiliary

receiver, a T/R relay, filtering equipment (intermodulation panel, etc.), batteries and

charger, and an antenna system. Remote base stations normally require more

extensive filtering equipment and cavities than local base stations due to increased

frequency interference problems caused by multiple users at remote sites. A

remote base station is connected to a communications center’s dispatch console.

Remote base stations are used by dispatch to communicate to vehicles on the

primary and BLU frequencies. The “C” channel is used to transmit to the vehicles

and the “S” channel is used to listen to vehicles.

5.4. Remote Sites Versus Local Sites.

5.4.1. Base stations are located at radio sites. The term “remote site” is

generally used for radio sites that are located at remote locations. Most

of the time remote sites are located on mountain tops. Base stations at


remote sites are controlled by dispatchers via microwave circuits, RF

control links (usually 70 MHz, 150 MHz or 450 MHz), or leased telephone

lines.

5.4.2. The term “local site” is generally used for radio sites that are located in

cities. Most local sites are communications centers or area offices. At

local sites, since the radio vaults either share the same building as the

communications center or are located right next to the communications

center, the radios at local sites are generally controlled via house cables.

5.5. Continuous Tone Coded Squelch System (CTCSS).

A squelch system that uses a specific sub-audio tone (usually 50-200 Hz) in

conjunction with an RF carrier. This type of squelch system allows two or more

radio systems to share the same radio channel without interference to one another.

CTCSS is sometimes referred to as Private Line (PL) and Channel Guard (CG).

5.6. Auxiliary Receiver.

A standalone receiver unit that is not physically part of a transmitter.

6. Control of Base Stations


In the CHP Lowband Radio System, each base station is controlled by a console.

Each base station is connected to that console by means of microwave circuits,

leased telephone lines, VHF or UHF radio control links, physical cables, or any

combination of these.

6.2. Local Base Station Control.

A local base station is generally located at an area office and is controlled by a

desktop console located in that office. Control of the local base station at an area

office is accomplished by cross connecting the base station to the desktop console

via physical cables (i.e., house cables).

6.3. Remote Base Station Control.

A remote base station is located at a remote site that is generally far from a

Desktop Console

communications center. It is controlled by a dispatch console located at a

communications center. The control of a remote base station is accomplished by

cross connecting the remote base station to the communications center’s dispatch

console via microwave circuits, leased telephone lines, VHF or UHF radio control

links, physical cables, or any combination of these.

6.4. Types of Control Circuits.

The types of control circuits are microwave circuits, leased telephone lines, VHF or

UHF radio control links and physical cables.

6.4.1. Microwave Circuits.

Microwave circuits can be state, other government, or privately owned

and they utilize either 4-wire tone or 4-wire E&M signaling.

6.4.2. Leased Telephone Lines.

Leased telephone lines are dedicated point-to-point “always on” phone

circuits leased from the phone company. CHP typically leases two types

of lines.

6.4.2.1. A 2002 voice grade unconditioned leased line used for voice

and/or in-band tone transmissions.

6.4.2.2. A 3002 data grade conditioned leased line used for voice, data

and facsimile transmissions.

6.4.3. 70 MHz / 150 MHz / 450 MHz RF Control Links.

Control links consist of fixed radio equipment operating in the 70 MHz,

150 MHz or 450 MHz range of frequencies to allow communications

between two radio sites. The fixed radio equipment is generally cross-

banded to the remote base station at the last remote site. The purpose of

RF control links is to allow a remote base station at a distant remote site,

which has no microwave or leased telephone lines available, to connect

to a site that has microwave or leased telephone lines in order to

ultimately connect to a communications center’s dispatch console.

6.5. Signaling Types.

6.5.1. Tone.

Tone signaling utilizes standard in-band tones (300 – 3000 Hz), such as

1950 Hz or 1850 Hz, on the transmit pair in order to enable the radio’s

Push-to-Talk (PTT).

6.5.2. Direct Current (DC).

DC signaling utilizes direct current on the transmit pair in order to enable

the radio’s PTT. DC signaling requires physical cable connections. DC

signaling has mostly been replaced by tone and E&M signaling.

6.5.3. E&M.

E&M signaling utilizes separate wire pairs for the “E” and the “M” leads in

order to provide contact closure to or from the radio to enable PTT or to

provide Carrier Operated Squelch (COS).

7. Communications Centers


The communications center (or dispatch center) is the nerve center of CHP’s

operations and radio communications. This is where all emergency and

non-emergency telephone and radio calls are received, recorded, processed and

communicated or radioed to the field patrol units. CHP patrol units are dispatched

out of 25 CHP communications centers located throughout the State.

7.2. Dispatch Console Versus Desktop Console.

A dispatch console is substantially larger, more capable and is more expensive

than a desktop console. A dispatch console typically has several operator or

dispatch positions with multiple communication channels and features that are

supported by complex electronic equipment. In comparison, a desktop console is

small enough to sit on a desk and can control several communications channels.

A desktop console’s electronics are self-contained within the unit.

7.2.1. Main Equipment Package (MEP).

The MEP is the complex electronic equipment that supports all the

dispatch console positions and functions. This equipment occupies


multiple equipment racks that are located in the radio vault. Reference

Appendix A, Figure A3, Console MEP Example.

7.3. Dispatch Console Functions.

The following are a few of the more common dispatch console functions utilized by

CHP.

7.3.1. Vote Steer.

The Avtec dispatch console employs internal voting equipment to select

the best receive audio (voted audio) to present to the dispatcher. The

dispatch console would then steer the dispatcher’s reply to the same

remote base station that the transmission originated from. This ensures

the best audio quality reception at the communications center and the

best possible reply. Reference Appendix A, Figure A1, CHP Vote Steer

Diagram.

7.3.2. Simulcast.

Simulcast is the capability to simultaneously transmit from several base

stations on the same frequency at the same time.

7.3.3. Patch.

The patch function is used to connect separate frequencies together to

allow disparate frequencies to communicate with each other. The

dispatcher enables the console’s patch function to automatically

retransmit the receive audio from one channel out on one or more

different channels, and vice versa, within the dispatch console.

7.3.4. Repeat.

The repeat function allows receive audio to be transmitted out on one or

more remote base stations to allow field units to hear inbound traffic.

8. Lowband System


The CHP Lowband Radio System is configured as a two-frequency simplex

system. The remote base station transmits to the mobile units on one frequency

designated "C” channel and the mobile units transmit to the remote base station on

a different frequency designated "S” channel. Reference Appendix A, Figure A4,

CHP Lowband Radio System Diagram.


8.2. Frequencies.

Currently, forty-seven different frequency pairs are used throughout the State. For

ease of identification, each pair is referred to as a color. Reference Appendix A,

Figure A5, CHP Lowband Frequencies – Open List, for a listing of the colors and

their respective frequencies. The motorcycle and mobile radios are synthesized

programmable units equipped to monitor both the "S" and "C" channels.

8.3. Control Circuits.

The CHP Lowband Radio System is a remote base station type system. Each

remote base station is individually controlled from its associated communications

center by means of microwave circuits, leased telephone lines, VHF or UHF radio

control links, physical cables, or any combination of these.

8.4. Patrol Area.

The patrol area of each area office is assigned a color as its primary frequency in

addition to a secondary frequency (i.e., Blue). Reference Appendix A, Figure A6,

CHP Lowband Radio System Map and Appendix A, Figure A7, CHP Areas With

Primary Lowband VHF Channel Map for the frequency color assigned to each area

office. Multiple area offices may share the same primary frequency.


The CHP Lowband Radio System also uses a Continuous Tone Coded Squelch

System (CTCSS). CTCSS is also referred to as Private Line (PL) and Channel

Guard (CG). CTCSS is used for two reasons: first, to reduce, but unfortunately

not eliminate, the nuisance caused by skip interference from other states; and

second, a different CTCSS tone frequency is employed in each CHP division to

allow reuse of frequency colors more often within the State. The radio system,

being a two-frequency simplex system, also enhances the ability to reuse

frequencies. Reference Appendix A, Figure A5, CHP Lowband Frequencies –

Open List, for a listing of CTCSS frequencies assigned to each division.

8.6. Blue Frequency.

The Blue (BLU) frequency pair is employed on a statewide basis to provide radio

access from a mobile located anywhere in California. Mobiles are programmed to

operate on their assigned primary frequency pair and on the secondary BLU

frequency pair. In the secondary mode, CTCSS on the BLU receivers of the

remote base stations have been enabled allowing mobiles with the proper CTCSS


to access the BLU frequency and communicate with the dispatcher. CHP mobile

radios have the proper CTCSS programmed for both the primary and secondary

frequencies for the areas that they normally patrol. When operating in areas that

they normally do not patrol, color (frequency) and division (CTCSS) must be

manually selected by the officer. Allied agencies can access the primary or

secondary frequencies by using the CTCSS assigned to the CHP division. The

BLU frequency is also used as a secondary frequency for use during emergencies

and special details.

8.7. Communications Center Functions.

The communications center is the lifeline for the CHP officer. CHP field personnel

are dispatched out of 25 CHP communications centers located throughout the

State. The communications centers include a dispatch console that has the ability

to control and monitor multiple frequencies simultaneously.

9. UHF System


The CHP UHF Mobile Radio System provides both regional and local

communications between CHP communications centers, area offices, and officers

using mobile or portable radios. Various users of the CHP UHF Mobile Radio

System include the Governor’s Protective Detail (GPD), Office of Dignitary

Protection (ODP), Office of Capitol Protection (OCP), Office of Judicial Protection

(OJP) and various Guest Users.

9.1.1. The CHP UHF Mobile Radio System is a network of mobile relays in each

of the CHP divisions throughout the State. Each division has a minimum

of one communications center that has control of (or access to) a UHF

mobile relay in order to communicate with field units.

9.1.2. This radio system operates on frequencies in the UHF public safety

spectrum (450 to 470 MHz). Reference Appendix A, Figure A8, CHP

UHF Mobile Radio System Map, for locations of mobile repeaters,

frequencies used and CTCSS access tones.

9.2. Mobile Relay Versus Base Station.

A mobile relay repeats the communications of any field officer’s mobile or portable

radio as well as that of a control station radio at CHP area offices. The mobile

relay is also connected to the communications center. This repeat capability of the


station enables all units to hear each other and; therefore, both sides of a

conversation are heard. In comparison, a non-repeating base station (such as that

used in the lowband VHF system) only connects a dispatcher to mobile radios and

vice versa which does not allow field officers to hear each other.


The mobile relays are accessed by mobile and portable radios using one of eight

Continuous Tone Coded Squelch System (CTCSS) access tones. Any mobile or

portable radio on the system can hear the output of all the mobile relays within its

coverage area, but transmissions from a field radio through a specific mobile relay,

in a desired geographic area, is based on the selection of that particular mobile

relay’s repeater access tone on that field radio.

9.4. Control Circuits.

Each mobile relay is also individually controlled from its associated

communications center by means of microwave circuits, leased telephone lines,

VHF or UHF radio control links, physical cables, or any combination of these.

9.5. Communications Center Functions.

CHP field personnel are dispatched from CHP communications centers located

throughout the State. The major centers involved with the UHF system can be

found on the attached map (reference Appendix A, Figure A8, CHP UHF Mobile

Radio System Map). The communications centers include a dispatch console that

has the ability to control and monitor multiple mobile relays simultaneously. Each

center controls the mobile relays in its region.

9.6. Urban Area Radio System Configuration.

Strategically located mobile relays have been installed in some downtown areas to

supplement the weaker portable radio coverage in urban areas where the

mountaintop mobile relay coverage is marginal. Most of these downtown mobile

relays in a given urban area may also be part of a receiver voting system. This

voting system continuously selects the best receive audio from among all

connected mobile relay receivers and retransmits this voted audio back to other

field personnel as well as on to the communications center.

10. Mobile Equipment

10.1. Vehicle Equipment.

The typical CHP vehicle is equipped with a GE RangR lowband radio, a vehicular


repeater system (VRS) to extend the communication range of an officer outside the

vehicle and a programmable scanner receiver for cross-monitoring other agencies.

• GE RangR Radio – VHF Lowband Radio, CHP’s standard mobile radio, 100W

[Works in conjunction with a GE S-810 Control Head]

• VRS Repeater – VHF High Band Radio, GE Executive II or Pyramid SVR-200,

Approximately 300mW [Works in conjunction with a VHF High Band portable

radio (Motorola HT1000 @ approximately 2W)]

• Scanner – Multiband Receiver, Uniden BCD 996T

10.2. Vehicular Repeater System (VRS).

The VRS relays the main two-way lowband radio transmissions to and from officers

by means of a separate high band radio link to the personal portable radios they

are wearing. The high band radio link is a simplex 154.905 MHz frequency and is

protected by CTCSS (173.8 Hz or 156.8 Hz) for transmissions from the officer.

The portable has the capability to permit portable-to-portable communication on

the same frequency (no CTCSS transmitted) and for communication on the

154.920 MHz statewide mutual aid frequency (CLEMARS). The VRS is sometimes

referred to as the Automatic Vehicular Repeater (AVR).

11. Radio Equipment at Other Facilities

11.1. Area Offices.

A local lowband base station and a desktop console are found in typical area

offices. The desktop console, usually located in the Sergeants’ Office, controls the

local base station. The base station, located in a small radio vault, allows the area

office to communicate car-to-car (“C” channel) on the office’s primary and BLU

frequencies and to listen to the primary “S” channel. Radio traffic is typically

connected to the office’s PA system. Area offices do not have direct radio

communications with its communications center. Some area offices also have

multiband scanners.

11.2. Inspection and Scale Facilities.

Smaller inspection and scale facilities general use desktop lowband base stations

to communicate with their vehicles. Larger inspection and scale facilities may use

a base station installed in a radio vault and a desktop console for communications.

Inspection and scale facilities do not employ a standard radio channel configuration


scheme. Most inspection and scale facilities can talk car-to-car on their primary

and BLU frequencies and some can talk directly to their communications centers.

In the newer and larger inspection facilities, radio traffic is typically connected to

the office’s PA system.

11.3. Resident Posts (RP).

Most RPs do not have any fixed radio equipment. They rely on their vehicles to

communicate with their communications centers.

12. Public Safety Microwave System


12.1.1. The State’s Public Safety Microwave System consists of nine major

(backbone) and numerous local routes throughout the State.

12.1.2. The nine major routes are North Coast, North Valley, Truckee-Lassen,

South Coast, South Valley, East Sierra, Southern California, Sacramento

Local and Los Angeles Local. Reference Appendix A, Figure A9, Public

Safety Microwave System Map.

12.1.3. The nine major routes operate on the 6 GHz frequency band.

12.1.4. Local routes operate on the 960 MHz, 2 GHz, 11 GHz and/or 18 GHz

frequency bands.

12.1.5. The Public Safety Microwave System used to be comprised of all analog

microwave radios, baseband combiners and multiplex equipment. The

multiplex equipment interfaces with the customer’s voice traffic and

transforms it to one of the 600, 4 kHz wide, microwave channels using

Frequency Division Multiplexing (FDM). The analog microwave radios

then transmit the traffic from site to site throughout the State.

12.1.6. PSCD is currently converting the analog microwave system to a Time

Division Multiplexed (TDM) integrated digital network.

12.1.7. The new digital microwave network will ultimately be comprised of digital

microwave radios, Digital Cross-Connect Systems (DCS) and digital

Pulse Code Modulation (PCM) T1 channel banks.

12.1.8. The digital network utilizes digital channel banks to interface with the

customer’s voice traffic. The DCS then switches the traffic between

digital microwave radios and channel banks.


12.1.9. Currently PSCD has completed about 40% of the digital conversion with

the rest of the conversion scheduled to be completed in the next few

years.

12.2. Public Safety Switching System (Green Phone).

12.2.1. The Green Phone System is a State-owned statewide telephone system

designed to provide communications between all participating State

agencies during an emergency. The participating State agencies are:

California Highway Patrol (CHP), California Department of Forestry

(CDF), California Department of Transportation (CALTRANS), Office of

Emergency Services (OES), California Department of Parks and

Recreation (DPR), and PSCD.

12.2.2. The system utilizes the State’s Public Safety Microwave System and is

independent of the public telephone network.

12.2.3. The system is designed, installed and maintained by PSCD with high

reliability standards so it will remain in service during an emergency while

the public telephone system may fail or become too congested for

communications.

12.2.4. The system is comprised of two trunk switches, eleven PABX telephone

switches, and hundreds of subscriber units.

12.2.5. One of the two trunk switches is located at the Sacramento Microwave

Center and the other trunk switch is located at La Habra Peak in the Los

Angeles area. They are interconnected via the State microwave system.

12.2.6. The eleven PABX telephone switches are located at: Redding CDF,

Redding Microwave Center, Sacramento Microwave Center, Sacramento

Traffic Management Center, PSCD Headquarters, Vallejo CHP Division

Headquarters, Santa Rosa CDF, Riverside CDF District Office, Los

Angeles Regional Traffic Management Center, and San Diego DOT

Traffic Management Center. They connect and route telephone traffic

between subscriber units and the two trunk switches via the State

microwave system.

12.2.7. The subscriber units are telephone handsets (originally green) located at

the various State agencies. There are approximately 800 subscriber units

statewide. Each subscriber unit is connected to its assigned PABX


telephone switch via either the State microwave system or dedicated

leased telephone line.



This section is a discussion of the various aspects of the California Highway Patrol Enhanced

Radio System (CHPERS) project. It is assumed that the reader has a basic understanding of

the existing CHP radio system.

13. Simulcast Support in Existing Locations

13.1. Current simulcast areas are the Los Angeles Communications Center (LACC),

Golden Gate Communications Center (GGCC), Border Communications Center

(CC) and Inland CC. In a simulcast radio system, all transmitters on the same

frequency are keyed at the same time (i.e., simultaneous transmission of the same

information).

13.1.1. The GGCC simulcast radio system will not be included as part of the

CHPERS project (except as noted below), since there is a current CHP

project, which is unrelated to the CHPERS project, to replace the

simulcast control equipment and remote site base stations used by the

GGCC simulcast radio system.

13.2. Remote Site Simulcast Control Equipment.

The CHPERS project will replace existing remote site simulcast control equipment

because the equipment is beyond its amortized life expectancy and replacement

parts are costly and increasingly hard to obtain.

13.2.1. Remote site simulcast control equipment is the equipment (located at

remote sites) required to control and align a radio transceiver in order for

it to operate as a simulcast transmitter.

13.2.2. Remote site simulcast control equipment will be replaced for Border CC

and Inland CC under the CHPERS project.

13.2.3. Remote site simulcast control equipment associated with LACC and

GGCC have recently been or will soon be replaced as part of other

approved CHP projects unrelated to CHPERS; therefore, the CHPERS

project will only purchase replacement remote site simulcast control

equipment for GGCC and LACC for installation at a later date (after the


completion of the CHPERS project) as part of normal equipment

replacement.

13.2.4. Replacement of the existing remote site simulcast control equipment will

involve the following steps:

13.2.4.1. Temporarily relocating the equipment in the rack to make room

for the new equipment.

13.2.4.2. Installing and testing the new equipment.

13.2.4.3. Aligning and phasing the transmitters.

13.2.4.4. Disconnecting the old equipment and connecting the new

equipment when the new system is ready for cutover.

13.2.4.5. Completely removing the old equipment.

13.3. Remote Site Base Station Equipment (Simulcast).

The CHPERS project will replace remote site base station equipment (simulcast

lowband base station racks and associated radio equipment) because the

equipment is beyond its amortized life expectancy and replacement parts are

costly and increasingly hard to obtain.

13.3.1. Remote site base station equipment is generally comprised of an

equipment rack which contains a radio transceiver(s) and its ancillary

miscellaneous radio equipment, a Global Positioning Satellite (GPS)

reference receiver(s) and miscellaneous associated equipment.

13.3.2. Remote site base station equipment will be replaced for Border CC and

Inland CC under the CHPERS project.

13.3.3. Remote site base station equipment associated with LACC has recently

been replaced. Remote site base station equipment associated with

GGCC will soon be replaced as part of an approved CHP project

unrelated to CHPERS.

13.3.3.1. LACC’s recently replaced base stations will not meet FCC

licensing requirements for the new CHPERS frequency

assignments, the CHPERS project will replace these base

stations with FCC compliant lowband base stations. The base

stations that are to be replaced are fairly new; therefore, CHP


will keep and use these base stations as back-up parts for

other radios currently operational.

13.3.3.2. GGCC’s current project’s replacement base stations will also

not meet FCC licensing requirements for the new CHPERS

frequency assignments, the CHPERS project will provide

newer FCC compliant lowband base stations for installation

under the current GGCC project. The current GGCC project’s

original replacement base stations are fairly new; therefore,

CHP will keep and use these base stations as back-up parts

for other radios currently operational. The CHPERS project

will also purchase replacement RF equipment for GGCC for

installation at a later date (after the completion of the CHPERS

project) as part of normal equipment replacement

13.3.4. Replacement of the existing simulcast base station equipment racks will

involve the following steps:

13.3.4.1. Temporarily relocating the existing rack to make room for the

new rack.

13.3.4.2. Installing and testing the new rack.

13.3.4.3. Aligning and phasing the transmitters.

13.3.4.4. Disconnecting the old rack and connecting the new rack when

the new system is ready for cutover.

13.3.4.5. Completely removing the old rack.

13.4. Dispatch Simulcast Control Equipment.

CHPERS will replace the existing dispatch simulcast control equipment at Border

CC and Inland CC. The existing dispatch simulcast control equipment at GGCC

and LACC will not be replaced since that equipment has recently been or will soon

be replaced; therefore, the CHPERS project will only purchase replacement

dispatch simulcast control equipment for GGCC and LACC for installation at a later

date (after the completion of the CHPERS project) as part of normal equipment

replacement.

13.4.1. Replacement of the dispatch simulcast control equipment at Border CC

and Inland CC is necessary due to the age and obsolescence of the


existing equipment. Border CC and Inland CC are currently using

simulcast control equipment that utilizes 15 year old technology.

13.4.2. Replacement of the dispatch simulcast control equipment at these

communications centers will involve the following steps:

13.4.2.1. Temporarily relocating the existing dispatch simulcast control

equipment to make room for the new dispatch simulcast

control equipment.

13.4.2.2. Installing and testing the new dispatch simulcast control

equipment.

13.4.2.3. Aligning and phasing the system.

13.4.2.4. Disconnecting the old dispatch simulcast control equipment

and connecting the new dispatch simulcast control equipment

when the new system is ready for cutover.

13.4.2.5. Completely removing the old dispatch simulcast control

equipment.

13.5. As required, replace antennas (that are more than 5 years old), heliax cables,

cavity filters and install additional cavity filters at all simulcast remote sites to

facilitate duplex operation.

13.5.1. Replacement of older antennas is necessary to ensure maximum RF

coverage and performance.

13.5.2. Replacement of heliax cables is necessary to reduce RF signal loss.

13.5.3. The CHPERS project includes the replacement of existing cavities and,

as required, the installation of additional cavities to enhance the radio

system. Cavities are used to filter out unwanted radio signals which can

cause interference to the desired receive and transmit signals, as well as

allows several base station transmitters to be coupled to a shared

transmit antenna.

13.6. The existing voting equipment (which is currently part of the Avtec dispatch

consoles) will be replaced when new dispatch consoles are procured.

13.6.1. CHP’s simulcast radio systems use the voting equipment to select which

receive audio is presented to the dispatcher and which audio is

retransmitted to the mobile units. The voting equipment receives audio


from multiple sites, evaluates which audio is the best receive audio (voted

audio), and then presents the voted audio to the dispatcher. This voted

audio is also sent to the associated simulcast transmitter sites and

broadcasted to the mobile units.

13.6.2. The CHPERS project will purchase new dispatch consoles to replace the

current CHP dispatch consoles. The CHPERS project will also purchase

backup desktop consoles.

13.6.3. If the new dispatch consoles do not include built-in voting equipment, then

external voting equipment must be purchased.

13.7. New frequency pairs will be assigned to each simulcast area to facilitate duplex

operation. Duplex operation allows both transmit and receive functions to occur

simultaneously (i.e., the dispatcher can still hear inbound radio traffic from a site

that is currently being used to transmit).

13.8. Under the re-scope of the CHPERS project, CHP will continue to use vote steer in

communications centers that are not currently operating with simulcast systems. In

a vote steer radio system, receive audio from multiple sites is voted (as is

implemented in a simulcast radio system) and the best receive audio (voted audio)

is presented to the dispatcher. The vote steer radio system then automatically

selects the transmitter associated with the voted audio as the transmitter that

dispatch uses to reply to a mobile. Typically only one transmitter is selected at any

given time. [Occasionally, in some limited areas, more than one transmitter may

be configured to transmit simultaneously if their radio coverage areas are in

isolated non-interfering regions. This configuration enables transmission to a

greater number of mobile units during each single transmission].

14. Frequencies

14.1. BLU Frequency Separation

14.1.1. Each non-simulcast division will have a new unique division wide BLU

frequency pair (automatic vote steer using the current Avtec dispatch

console’s repeat function1) using one of the newly identified lowband

frequency pairs.

1 The Avtec dispatch console’s repeat function will not provide full area repeat coverage. If too many sites are selected to repeat, then simulcast interference problems are inherently introduced. Engineering must judiciously


14.1.1.1. A unique division wide BLU frequency pair for each division

will permit each division to utilize their BLU channel for local

incidents without interfering with the operations of neighboring

divisions.

14.1.1.2. The current statewide BLU frequency pair (42.34 / 42.18 MHz)

and most primary frequency pairs are usually too close in

frequency to have both of the channels operate simultaneously

due to frequency interference. Therefore, a new BLU

frequency pair will be required such that both the BLU channel

and the primary channels can be operated independently and

simultaneously with minimal interference.

14.1.2. Border Division and Inland Division (except for the areas dispatched by

Border CC and Inland CC) will each have a new unique division wide BLU

frequency pair (automatic vote steer using the current Avtec dispatch

console’s repeat function1) using one of the newly identified lowband

frequency pairs.

14.1.2.1. The simulcast areas dispatched by Border CC and Inland CC

will each have a different BLU simulcast frequency pair

different from the conventional BLU frequency pair used in the

remainder of their respective divisions. Both Border CC and

Inland CC utilize simulcast radio systems while the remainder

of their respective divisions use conventional radio systems.

The two radio systems are non-compatible.

14.1.3. Golden Gate Division and Southern Division will each have a new unique

division wide BLU simulcast frequency pair since each of these divisions

are entirely controlled by a single communications center (GGCC and

LACC, respectively).

14.1.4. The new division wide BLU frequency pairs will be referred to as the

division’s Tactical (TAC) frequency.

14.1.5. The separation of the BLU frequency will require the installation of new

dedicated BLU base stations at remote radio sites. The new BLU base

select a site(s) that will provide the most repeat audio coverage without introducing simulcast interference in the intended coverage area.


stations will be installed at the same remote radio sites that previously

shared a PRI/BLU base station. New dedicated BLU base stations will be

comprised of, at a minimum, the following:

14.1.5.1. Radio transceiver

14.1.5.2. Filtering equipment (cavities, etc.)

14.1.5.3. Ancillary miscellaneous radio equipment

14.1.5.4. Antenna system and cabling

14.2. Primary Frequency

Each area’s existing primary frequency pair will be replaced with a different primary

frequency pair (with 2 to 3 MHz separation between the TX and RX frequencies)

which will facilitate duplex operation. The new CHPERS frequency plan, CHPERS

Lowband Frequency Plan, can be found in Appendix C, Figure C7.

The CHPERS Lowband Frequency Plan will indicate the final lowband frequency

pair assignment that will be used in each CHP area. On the frequency plan, the

assigned final frequencies were carefully selected in order to avoid frequency

interference issues between CHP areas and other licensed users. The CHPERS

Lowband Frequency Plan consists of three phases.

14.2.1. Phase 1: Interim Frequency Plan Map with Some Split Dispatch Regions.

This map shows the transmit and receive frequencies that are required to

be used during the frequency cutovers to eliminate interference between

adjacent CHP areas. Some of the receive frequencies are interim

frequencies. These interim frequencies will need to be changed to their

final frequencies at a later date. This map includes the GGCC Aqua and

Fresno Pink frequency splits.

14.2.2. Phase 2: Final Frequency Plan Map with Some Split Dispatch Regions.

This map shows the final transmit and receive frequencies that are

required to be used by CHP areas to eliminate interference between

adjacent CHP areas (i.e., the interim frequencies have been changed).

Implementation of these final receive frequencies will require some

mobile reprogramming.

14.2.3. Phase 3: Final Frequency Plan Map with All Known Future Split Dispatch

Regions.


This map shows the final transmit and receive frequencies, as well as, the

new (final) frequencies required for the future frequency splits for the

Stockton White, Chico Brown, Merced Orange and Merced Yellow areas.

Implementation of these splits will require mobile reprogramming.

14.3. UHF Frequency

The CHP, with the assistance of the Public Safety Communications Division

(PSCD), will continue to seek frequencies, as they become available in the UHF

band, to enhance the current capabilities (tactical channels) of the CHP radio

system.

14.4. 700 MHz Frequency

14.4.1. The CHPERS project has acquired a portion of the soon to be available

700 MHz frequencies for use with the vehicle repeater system and for use

at area offices and inspection, scale and air operations facilities.

14.4.2. The 700 MHz frequencies will become available in those remaining

(generally urban) regions when analog television broadcasting is

converted to digital broadcasting in June 2009.

14.4.3. CHP has petitioned the Public Safety Radio Strategic Planning

Committee (PSRSPC) and has secured the required 700 MHz

frequencies (sixteen for VRS use and an additional eight for base station

use). Actual 700 MHz frequency assignments for use in specific

geographic regions will be accomplished once final analysis of service

and interference areas have been completed.

14.5. Car-to-Car Frequency

The car-to-car frequency will continue to use the lowband frequency band.

14.6. Frequency Splits

The following frequency splits are not part of the CHPERS project. They are

projects managed by CHP Telecommunications Section (CHP-TS). However, the

CHPERS project will assist in the implementation of the Fresno PNK split. These

splits will be implemented at a later date after the completion of the CHPERS

project.

14.6.1. GGCC AQA (Work Authorization issued)


14.6.2. Barstow WHT (potential future split)

14.6.3. Stockton WHT (Work Authorization issued)

14.6.4. Chico BRN (Work Authorization issued)

14.6.5. Merced ORG (Work Authorization issued)

14.6.6. Merced YEL (potential future split)

14.6.7. Fresno PNK (Work Authorization issued)

15. Use of Vote and Steer

15.1. Per CHP direction, the CHPERS project will continue to use vote steer in all areas

except Border CC, Inland CC, LACC and GGCC. Simulcast radio systems will

continue to be used in the four aforementioned communications centers.

15.2. In a vote steer radio system, receive audio from multiple sites is voted (as is

implemented in a simulcast radio system) and the best receive audio (voted audio)

is presented to the dispatcher. The vote steer radio system then automatically

selects the transmitter associated with the voted audio as the transmitter that

dispatch uses to reply to a mobile. Typically only one transmitter is selected at any

given time. [Occasionally, in some limited areas, more than one transmitter may

be configured to transmit simultaneously if their radio coverage areas are in

isolated non-interfering regions. This configuration enables transmission to a

greater number of mobile units during each single transmission].

16. Add Inbound Repeating to Critical Conventional Vote and Steer Areas

16.1. The current Avtec dispatch consoles’ repeat function will be enabled for all

conventional primary vote steer frequencies and for all conventional BLU/TAC vote

steer frequencies.

16.2. The primary simulcast and the BLU/TAC simulcast frequencies at GGCC, LACC,

Border CC and Inland CC will be repeated via the current Avtec dispatch consoles’

simulcast repeat function.

16.3. In order to avoid coverage overlap (simulcast interference) problems in

conventional non-simulcast areas, PSCD engineering must judiciously select an

optimum remote site (or sites) that will provide the most repeat audio coverage

(i.e., maximize the area that repeat audio is heard) without introducing coverage

overlap (simulcast interference) problems in the intended geographical coverage


area. Repeat sites will be determined by PSCD at a later date by using computer

generated RF propagation coverage analysis software.

16.4. Vote steer repeat coverage will not cover the entire conventional vote steer

geographical area of operation since not all transmitters will be on at the same

time.

16.5. It must be understood that vote steer repeat is not currently used in the

conventional vote steer geographical areas and that this repeat scheme is an

“enhancement” over having no repeat coverage.

17. CPVE for Interoperability and Network / Radio Integration

17.1. The CHPERS project will acquire a Consolidated Patrol Vehicle Environment

(CPVE) and associated new mobile radios. The CPVE is a technology driven,

hardware and software system that will allow for radio interoperability on multiple

public safety radio frequency bands and will consolidate all radio, mobile digital

computer, emergency lights and siren control functions, and additional functions

into one radio control head.

17.2. In addition to the CPVE, the CHPERS project will replace the existing obsolete

(1980’s vintage) lowband mobile radios with an industry-standard lowband mobile

radio.

17.3. The CHPERS project will also install additional industry-standard mobile radios (on

different frequency bands) in the patrol vehicles. Using these additional mobile

radios, the CPVE will be able to connect disparate radio systems together to

achieve “user level” interoperability.

17.4. The CPVE will also include a 700 MHz vehicle repeater system (VRS).

17.4.1. The VRS will allow officers to use the mobile radios in the patrol vehicle

while standing some distance away from the vehicle.

17.4.2. The VRS will also give the officers the ability to control the vehicle’s

mobile radios remotely and be able to switch from the primary channel to

tactical and emergency channels and change radios without returning to

the vehicle.


18. 700 / 800 MHz Extended Range for Portable Communications

18.1. For portable radio communications, CHP officers will use a 700/800 MHz portable

radio which can communicate with the 700 MHz VRS which will be acquired as

part of the CPVE.

18.2. In order for the CHP enforcement officers to have radio communication outside of

the vehicle, each enforcement vehicle is to be equipped with a VRS to extend

mobile radio capabilities.

18.2.1. While away from the vehicle, the officer will use a 700/800 MHz portable

radio to control the vehicle’s mobile radios via the VRS and CPVE.

18.2.2. Control from the portable radio is achieved by physical channel/mode

switch selections on the portable.

18.2.3. The portable radio is to be programmed with channels using different 700

MHz frequency pairs along with a different Project 25 (P25) Network

Access Code (NAC) signaling code for each of these frequency pairs.

When a vehicle is used in a specific primary dispatch channel area,

selecting a specific NAC code on the assigned 700 MHz VRS link

channel assigned to that area will cause portable radio communications

with the VRS to be steered to, and repeated on, a specific mobile radio

and channel. The required 700 MHz frequency pairs have not yet been

assigned for VRS operation.

18.2.4. The specific association between portable radio channel and NAC code

and the corresponding mobile radio and channel are to be predefined in

the CPVE in a Radio Channel Assignment Table (RCAT) (yet to be fully

developed).

18.2.5. When operating outside of the normally assigned patrol area, the

selection of that new geographic area on the CPVE will cause the

automatic selection of the corresponding 700 MHz VRS link frequency

pair for portable radio operation in that new area. This enables this

vehicle to function in the same way as other vehicles normally assigned

to the area.

18.2.6. The VRS unit will also be equipped with the necessary logic to prevent

multiple VRS units from transmitting simultaneously and causing


interference when they are on the same 700 MHz link frequency and in

the same vicinity.

18.3. The 700 MHz VRS radio link will operate on a duplex frequency pair using P25

Phase 1 digital modulation and will be protected against nuisance interference by

NAC signaling on transmissions between the officer and the vehicle.

18.4. It shall be possible for a user to remotely activate the VRS’ system mode of

operation from a portable radio on the VRS link channel. The system mode will

enable repeat operation of portable radio transmissions through a selected mobile

radio in the vehicle as well as repeating portable to portable transmissions.

18.5. A capability exists in the CPVE to allow a portable radio on the link channel to

connect the VRS to any preconfigured cross patch radio bus. This VRS

connection will be done without causing a cross repeat between radios of

independent radio buses. The mobile radios on each independently configured

radio bus are still to cross repeat only with radios on the same bus, but with the

addition of the VRS when connected. The ability to switch the VRS connection

onto or off of any of these cross patch buses from a portable radio is to be

achieved by the selection of specific channel switch positions dedicated to these

cross patch buses.

18.6. The actual operating distance between the portable radio and the VRS (CHP has

proposed one to two miles) will need to be determined. This distance is over open

ground. Buildings and other obstructions will reduce the effective operational

distance. Some operational scenarios will require operation at reduced power to

achieve shortened distances in order to minimize interference between users of

independent operations, especially in denser urban regions.

18.7. If the portable radio is properly and legally programmed, the CHP portable radio

will be able to communicate directly with other agencies’ 700/800 MHz radio

systems thus achieving an additional method of radio interoperability.

18.8. Frequency analysis of the Public Safety 700 MHz band included the determination

of the reuse of a 700 MHz channel for efficient spectrum use. One example is

shown in Figure C1 in Appendix C.

18.9. The specific 700 MHz channels being evaluated for the VRS link channels are

shown in Figure C2 (Base Channels) and Figure C3 (Mobile Channels) in

Appendix C.


19. Replacement of CHP’s Radio Infrastructure

The CHPERS project will replace CHP’s radio equipment infrastructure which is past its

useful life expectancy. Additionally, where feasible and cost effective, the CHPERS

project will also replace radio vaults and towers that do not meet the State’s requirements

and/or are in need of major structural improvements or repairs via the Capital Outlay

Budget Change Proposal (COBCP) process. DGS Real Estate Services Division (DGS-

RESD), Project Management Branch (PMB), will assist CHP in the implementation of any

Capital Outlay projects.

19.1. Facility Enhancements

19.1.1. The CHPERS project will provide the following facility enhancements:

19.1.1.1. When equipment (CHP and/or non-CHP) movement is

required to create space in radio vaults, CHP will pay the cost

of moving the equipment.

19.1.1.2. When antenna (CHP and/or non-CHP) movement is required

to create space on antenna towers, CHP will pay the cost of

moving the antenna and will pay for testing to ensure the

performance of that antenna is not adversely affected.

19.1.1.3. At sites where batteries can be consolidated into a battery

bank to create additional space in the radio vault, CHP will pay

the cost of moving and consolidating those batteries.

19.1.1.4. At non-capital outlay sites, deteriorating radio vault buildings

may be replaced with prefabricated radio vaults where

feasible.

19.1.1.5. Replacement of some radio vaults and towers that do not meet

the State’s requirements and/or are in need of major structural

improvements or repairs will be done by the COBCP process.

19.1.2. The CHPERS project will not provide:

19.1.2.1. Additional fencing.

19.1.2.2. Concrete walls around propane tanks.

19.1.2.3. Installation of “No Trespassing” signs.

19.1.2.4. Alarms or video surveillance.


19.1.3. Additionally, the CHPERS project will replace all roof mounted towers and

all wood telephone pole antenna structures at CHP remote sites and

facilities with self supporting towers.

19.1.4. The CHPERS Unit will work in conjunction with DGS-RESD and DGS-

PMB, to coordinate, schedule and construct any required new vaults and

towers.

19.1.5. PSCD will help to identify vaults and towers that need modification and/or

replacement and will develop vault and/or tower specification

requirements.

19.1.6. Currently, all COBCP sites have not yet been identified. Identification is

an ongoing effort. Additionally, sites that are designated as COBCP may

be changed to a non-COBCP site at a later date. Refer to Appendix B for

a list of sites currently identified as requiring facility upgrades via the

COBCP process.

19.2. Remote Sites

19.2.1. If new remote sites are needed, the following site selection methodology

(in order of preference) will be used:

19.2.1.1. Use existing vote steer sites that have existing State

microwave.

19.2.1.2. Use existing vote steer sites that are planned to have State

microwave.

19.2.1.3. Use existing State microwave sites.

19.2.1.4. Use existing State VHF sites.

19.2.2. Proposed remote site hardware enhancements:

19.2.2.1. Replace, as necessary, obsolete CHP radio equipment.

19.2.2.2. Replace existing lowband base stations except those

associated GGCC. The CHPERS project will purchase

replacement lowband base stations for GGCC. However,

these new lowband base stations will be installed as part of a

current project which is unrelated to CHPERS.

19.2.2.3. Replace all existing CHP UHF and 150 MHz control link circuit

base stations.


19.2.2.4. CHP’s 70 MHz control link circuit base stations will not be

replaced. However, the CHPERS project will purchase

replacement 70 MHz control link base stations for installation

at a later date after the completion of the CHPERS project.

19.2.2.5. As necessary, replace all antennas that are more than five

years old.

19.2.2.6. Where practical, replace all RF transmission lines with 7/8”

heliax cable to reduce system loss.

19.2.2.7. Install a second lowband base station when separating the

BLU from the primary base station.

19.2.2.8. Fully duplex the primary and BLU base stations using newly

identified lowband frequency pairs.

19.2.2.9. Replace all existing cavity filters and install additional cavity

filters, as required, to facilitate duplex operation.

19.2.2.10. Install separate lowband TX and RX antennas.

19.2.2.11. Install required lowband TX combiners.

19.2.2.12. Install required lowband RX splitters, multicouplers and/or

amplifiers.

19.2.2.13. Deleted.

19.3. Communications Centers

19.3.1. The CHPERS project will continue to use vote steer in all areas not

currently simulcasted while simulcast will continue to be used in all areas

that are currently simulcasted.

19.3.2. Communications centers will vote steer their BLU/TAC frequencies similar

to the method currently employed.

19.3.3. The current Avtec dispatch console's repeat function1 will be used to

repeat the best voted audio.

19.3.4. Communications centers will be connected to each other via a dedicated

State microwave Wide Area Network (WAN) system, utilizing the new

State digital microwave system, configured for voice traffic priority and

quality of service to support the newer generation Voice Over Internet

Protocol (VoIP) dispatch consoles.


19.3.5. It is assumed that the existing voting equipment (which is currently part of

the Avtec dispatch consoles) will be replaced when new dispatch

consoles are procured.

19.3.6. Replace the existing radio equipment at communications centers with

newer equipment that includes enhanced features.

19.3.7. Refer to Appendix B for a list of CHP’s communications centers.

19.4. Area and Division Offices

19.4.1. Replace existing radio equipment at area and division offices with newer

equipment that includes enhanced features.

19.4.2. Provide each area and division office with the same lowband radio

functionality they currently have.

19.4.3. Deleted.

19.4.4. Install a desktop console to perform the following.

19.4.4.1. Deleted.

19.4.4.2. Control the lowband base station and other local radio

equipment.

19.4.5. The CHPERS project will install new 700/800 MHz base stations at all

area offices and some division offices.

19.4.6. Refer to Appendix B for a list of CHP’s area offices.

19.5. Inspection Facilities

19.5.1. At each inspection facility, the CHPERS project will install a lowband

control station on the appropriate frequencies to allow access to their

primary and BLU/TAC frequencies.

19.5.2. Additionally, the CHPERS project will install a 700/800 MHz base station

(cross-banded to the lowband control station) to allow officers in the

inspection bays using 700 MHz portable radios to have direct

communications with their communications center.

19.5.3. If necessary, desktop consoles will be installed to control the control

stations.


19.5.4. Each inspection facility will have unique operational needs as defined by

CHP. At a minimum, the inspection facilities will have the same lowband

communications functionality that they currently have.

19.5.5. As practical, radio equipment will be removed from inspection facilities

that can access, via the 700 MHz portable radios, the 700/800 MHz base

station at adjacent inspection or scale facilities. CHP will make this final

determination.

19.5.6. Refer to Appendix B for a list of CHP’s inspection facilities.

19.6. Scale and Air Operations Facilities

19.6.1. Scale and Air Operations Facilities

19.6.1.1. Scale Facilities

19.6.1.1.1. Each scale facility will have unique operational

needs as defined by CHP. At a minimum, the

scale facilities will have the same lowband

communications functionality that they currently

have.

19.6.1.1.2. As required, replace the lowband base station or

desktop base station and ancillary equipment with

a lowband control station to allow access to the

lowband radio system.

19.6.1.1.3. Install a 700/800 MHz radio base station (cross-

banded to the lowband control station) to allow

officers in the inspection bays, using 700 MHz

portable radios, to have direct communication

with their communications center.

19.6.1.1.4. As practical, radio equipment will be removed

from scale facilities that can access, via the 700

MHz portable radios, the 700/800 MHz base

station at adjacent scale or inspection facilities.

CHP will make this final determination.

19.6.1.1.5. Install a (or replace the) desktop console, as

required, if replacement equipment is available.


19.6.1.2. Air Operations Facilities

19.6.1.2.1. Replace the lowband base station or desktop

base station and ancillary equipment.

19.6.1.2.2. Install a (or replace the) desktop console, as

required, if replacement equipment is available.

19.6.1.2.3. Install a new 700/800 MHz radio and ancillary

equipment.

19.6.1.2.4. Avionics radios will not be replaced since

replacement equipment is not available.

19.6.2. Deleted.

19.6.3. If the newly installed control stations are not desktop units, then the

CHPERS project will install desktop consoles to control these stations.

19.6.4. The CHPERS Unit will identify any other CHP locations that will require

fixed radio equipment and will make a determination as to what

communications capability each location will have.

19.6.5. Refer to Appendix B for a list of public scales, resident posts and other

CHP facilities.

19.7. Operational Cutover

19.7.1. The CHPERS project will implement operational cutover using a phased

approach with each area/frequency having its own cutover date.

However, in some cases, multiple frequencies within a communications

center may be cutover at the same time to alleviate technically

challenges.

19.7.1.1. Each area/frequency affected by a cutover will be advised that

communications and day-to-day operations will be impacted

during the cutover.

19.7.1.2. A comprehensive operational cutover plan, for each

area/frequency, will be jointly developed between CHPERS

Unit, CHP-TS and PSCD to minimize the actual total time that

communications and day-to-day operations are impacted.

19.7.2. In order to reduce communications and day-to-day operations down time,

the following must be completed prior to the operational cutover date.


19.7.2.1. All affected vehicles must be reprogrammed.

19.7.2.2. All affected remote sites must have its new equipment

installed and ready to cutover.

19.7.2.3. All affected communications centers must have its dispatch

consoles reprogrammed, to the extent possible, and ready to

cutover.

19.7.3. Affected area and division offices, inspection, scale and air operations

facilities do not need to cutover at the same time as the operational

cutover; however, they should be cutover as soon as possible after the

operational cutover date since they will be without communications.

20. Meeting FCC Requirements for Narrow Banding

20.1. Federal Communications Commission (FCC) regulations mandate that by 2011 all

new installations of 150 MHz and 450 MHz radio systems must be narrow banded

(12.5 kHz channel spacing) and that by 2013 all existing 150 MHz and 450 MHz

systems must also be converted to narrow band.

20.2. Mobiles, portables and control link circuit base stations will also need to be

changed and/or reprogrammed to meet the FCC narrow band requirement.

20.3. The CHPERS project will purchase replacement 150 MHz and 450 MHz fixed base

and control link circuit base station equipment. The CHPERS project will install the

150 MHz equipment. However, the CHPERS project will only install the 450 MHz

equipment (in wide band mode) at only those sites where the CHPERS project will

be replacing other equipment.

20.4. The replacement (under a concurrent project) of the other existing UHF wideband

equipment may occur in parallel with the implementation of the CHPERS

requirements.

20.4.1. In some cases, the replacement of UHF wideband equipment in some

divisions will occur prior to CHPERS implementation in those divisions to

ensure that the new UHF narrow band equipment can be cutover on a

statewide basis at the same time.


21. Acquisition of Additional Radio Spectrum (Area, Division, Statewide)

21.1. An overview was developed of lowband VHF spectrum for public safety use, as

shown in Figure C4 of Appendix C. This overview identified existing frequencies

currently used by CHP as well as blocks of frequencies where additional spectrum

with sufficient frequency separation might be obtained for use as new mobile relay

based channels.

21.2. Some additional lowband VHF frequencies have been identified for supporting the

additional capabilities required by the CHPERS project.

21.2.1. Frequencies in this newly identified group are authorized by the FCC for

use by state police agencies, but only if a frequency is identified in a

National Plan as being approved for use by a particular state. To

minimize interference on these frequencies for nationwide use, they each

must be incorporated into the National Plan and identified as to which

states are eligible to use which frequency. Following that first step of

getting additional frequencies placed on the National Plan for use by the

State of California, the following steps have also been accomplished: 1)

Obtaining the necessary frequency coordination by APCO and 2)

Obtaining a FCC license modification to add these frequencies to CHP’s

mobile license.

21.3. An additional frequency analysis was performed to locate potential additional

lowband VHF frequencies and to lay out a statewide lowband VHF frequency plan.

Refer to the CHPERS Lowband Frequency Plan, Figure C7, Appendix C.

21.3.1. This analysis included searches for areas of the State where potential

frequencies might be used by CHP and that would not interfere with

existing State or non-State agencies. See Figure C5 in Appendix C for an

example of a search result showing areas of the State where a frequency

is already licensed by other agencies.

21.3.2. Results of an extensive frequency search of many frequencies showed

the areas of the State where different frequencies were potentially

available. See Figure C6 in Appendix C for a summary table of lowband

VHF spectrum and areas of potential use for these frequencies.

21.3.3. The frequency search results described above were taken one step

further by assigning frequencies to individual CHP areas and divisions in


a way that enabled frequencies to be re-used without interfering with

other areas or divisions, or other FCC licensees. See Figure C7 in

Appendix C for the assignment of lowband frequencies pairs throughout

the State based on channel requirements identified by CHP.

21.3.4. In an attempt to locate sufficient potential frequencies to support the

requirements identified by CHP, some frequencies listed in the frequency

plan (Appendix C, Figure C7) are based on assumptions that had to be

made at the time.

21.3.4.1. The frequency plan includes one “mobile only” 39 MHz

frequency that typically requires an FCC license waiver for use

as a base station transmit frequency. This frequency is

already licensed and is being used by CHP as a base station

transmit frequency for the existing COP1 channel. This

frequency will continue to be used as a base station transmit

frequency in the same area in the new system plan.

21.3.4.1. The frequency plan also includes a few frequencies that CHP

and California Youth Authority (CYA) share in Southern

California for temporary base station use, if necessary.

Two of these frequencies are also already licensed and

currently being used by CHP as fixed base station transmit

frequencies in Southern California; and will continue to be

used as base station transmit frequencies in the same area in

the new system.

A third frequency, also shared with CYA for temporary base

station use, is being planned for use as a new base station

transmit frequency in Southern California. Confirmation from

CYA will be required to confirm CHP’s base station use of this

frequency as the BLU1 frequency in the Inland Simulcast

region.

21.4. Modifications to the CHPERS Lowband Frequency Plan described above may be

necessary because of any of the following factors:

21.4.1. Changes to the total number of channels required in specific regions.

21.4.2. Deleted.


21.4.3. The fact that an FCC license for any planned radio site automatically

expires if equipment is not installed and the site made operational by the

time allotted by the FCC license.

21.4.4. The assumptions regarding the availability of a few of the frequencies

assumed earlier prove not to be true.

21.5. PSCD will inform CHP of available lowband frequencies that may become

available but will not actively pursue any additional frequencies other than

additional lowband frequencies that may be required to implement the CHPERS

project.

21.6. The CHPERS project intends to obtain additional frequencies in the lowband and

high band VHF bands and in the UHF band for future use. Additional UHF

frequency requirements can be determined once it is known where additional

coverage is required.

21.7. These additional frequencies will be used for area, division, and/or statewide future

operational requirements.

22. Dead Spot Mitigation

Dead spot mitigation is not part of the CHPERS project.

23. Integration of CHP Infrastructure With the State Digital Microwave System

23.1. PSCD is currently converting the State’s analog microwave system to a digital

microwave system which will support new agency needs and provide better

reliability with the use of higher quality circuits. This digital microwave conversion

effort is a legislatively approved PSCD project and is funded separately from the

CHPERS project.

23.1.1. The new State digital microwave system is a Time Division Multiplexed

(TDM) integrated digital network. Reference Appendix A, Figure A9,

Public Safety Microwave System Map, for a current map of the State

microwave system.

23.1.2. The network consists of nine major backbone routes. Each route consists

of digital microwave radios with the capacity of 28 DS1s, operating in the

6 GHz frequency band.


23.1.3. The network also consists of numerous local routes using 960 MHz, 11

GHz, and/or 18 GHz microwave radios.

23.1.4. The network utilizes Digital Cross-Connect System (DCS) to switch voice

or data traffic between digital microwave radios and digital T1 channel

banks.

23.1.5. T1 channel banks provide the interface (voice and data) between CHP

radio equipment and the digital microwave network at remote sites and

communications centers.

23.2. The CHPERS project will not replace any analog microwave equipment at CHP

remote sites, except as scheduled via the microwave conversion program.

23.3. The CHPERS project does not plan to install new microwave paths to replace

existing control link circuits (phone lines, 70 MHz, 150 MHz and 450 MHz control

links circuits). However, depending on funding availability, the replacement of

some existing control link circuits with microwave paths may occur. If so, PSCD

will assist CHP in identifying and prioritizing control link circuits for possible

conversion.

23.4. The CHPERS project will use microwave control link circuits (and install new

microwave paths, as needed) only when new CHP sites are developed or in

support of the existing CHP simulcast radio systems.

23.5. Receive only sites, if no State microwave is available, will continue to use leased

telephone lines or either VHF or UHF control link circuits.

23.6. CHP communications centers will be connected to each other via a State

microwave WAN system, utilizing the new State digital microwave system,

dedicated to CHP’s use, configured for voice traffic priority and quality of service.

23.6.1. To implement the above dedicated State WAN system, updated

microwave equipment (modems, multiplex shelves, ethernet converters,

etc.) will need to be installed at CHP communications centers.

23.6.2. If possible, the above dedicated State WAN system may be connected to

the existing CHP WAN depending on system compatibility and network

security.

23.6.3. The above dedicated State WAN system is required for the newer

generation VoIP dispatch consoles that will be purchased by CHPERS.


23.7. It is anticipated that the State digital microwave system, as it expands and

becomes more capable, in the future, may be expanded to include remote radio

sites for direct control of radio base stations via the WAN.

24. Communications Center Dispatch Console Upgrade

24.1. The CHPERS project will only purchase replacement communications center

dispatch consoles. Installation of the replacement consoles will be the

responsibility of CHP’s Telecommunications Section (CHP-TS) and they will be

installed under another CHP project unrelated to CHPERS.

24.1.1. CHP has determined that the current communications center dispatch

consoles (Avtec) are near the end of their useful life expectancy.

24.1.2. Installation of the new replacement communications center dispatch

consoles may occur in parallel with the implementation of CHPERS

requirements if the new consoles become available.

24.2. The CHPERS Unit will coordinate with CHP’s Communications Center Support

Section and CHP-TS to ensure all CHP’s requirements are included in any new

dispatch console purchase.

24.3. CHP communications centers will be connected to each other via a State

microwave WAN system as discussed above at a later date.

24.4. Basic functions and requirements of any new dispatch console are, but not limited

to, the following:

24.4.1. Provide the same functionality as the current Avtec consoles

24.4.2. Provide both simulcast and vote steer functionality

24.4.3. Provide inter-console control of remote sites in order to provide

redundancy (i.e., allow communications centers to back each other up)

24.4.4. Provide inbound voted audio repeat functionality

24.4.5. Provide VoIP capability

24.4.6. Project 25 (P25) capable

24.5. The operational cutover of any new dispatch console will involve the following:

24.5.1. The existing dispatch console needs to be moved to make space for the

new dispatch console; however, while moved, the existing dispatch

console must be kept operational.


24.5.2. Install the new dispatch console and connect it in parallel with the existing

dispatch console.

24.5.3. Perform training on the new dispatch console.

24.5.4. Perform functional and scenario testing to ensure all operational

requirements are met.

24.5.5. Perform functional and scenario testing to ensure the WAN can handle

the console’s voice and data requirements.

24.5.6. Disconnect the old dispatch console when the new system is ready for

cutover.

24.5.7. Completely remove the old dispatch console.

25. Radio Communications Interoperability Project (RCIP)

The enhanced radio system will support the RCIP without impacting departmental day-to-

day operations with the development and integration of a statewide radio interoperability

system design and by utilizing gateways and/or other electronic switching equipment

(consoles, VoIP, LAN/WAN, the State digital microwave system, and leased telephone

lines) to provide connectivity with other first responder systems. The enhanced radio

system will also support the creation of a new 700 MHz dedicated network hub system in

the 700/800 MHz frequency band, utilizing the newly allocated 700 MHz frequency

spectrum.

25.1. The installation of the JPS ACU-1000 interoperability gateways at the 25 CHP

communications centers, to provide regional interoperable capabilities, provides

connectivity between the gateway devices utilizing the Wide Area Interoperability

System (WAIS) to connect/link the communications centers, provides CHP with a

statewide network, provides future expansion capabilities, and provides an

immediate interoperability solution utilizing existing technologies.

25.1.1. The design of the gateway and/or electronic switching equipment will

provide connectivity by utilizing the WAIS system, in conjunction with the

LAN/WAN, the State microwave system, T1 lines, leased telephone lines,

and cellular/satellite providers, to create a network or series of statewide

networks. In addition, the system will interface with other local, state, or

federal government interoperability systems.


25.1.2. The design of the gateway or electronic switching equipment will provide

expansion capabilities to extend a geographical area of coverage.

Geographical areas will be extended utilizing remote radio sites, area

offices, portable (not handheld) radio devices, allied agency facilities,

and/or console units.

25.1.3. The design of the gateway or electronic switching equipment will provide

remote access to radio controls over IP based networks. Additionally, the

system design will provide interface cables for temporary installation of

allied agency radios.

25.1.4. The permanent connection of radio systems at multiple remote sites to

the gateway or electronic switching equipment using an IP network.

Various methodologies may be utilized for the connection of remote sites

(i.e., the State digital microwave system, leased telephone lines, or RF

control links).

25.1.5. The design and installation of a monitoring system at the Sacramento

Microwave Center to monitor system status of individual gateways,

electronic switching equipment, or networks.

25.1.6. A cache of pre-programmed mobile and portable radios (in various

frequency bands) to augment existing radios for use during a major

incident or disaster.

25.1.7. The design and installation of a console position channel connection to

the gateway or electronic switching equipment utilizing existing area office

consoles via lease telephone lines.

25.1.8. Provide coverage (propagation) maps of radios connected to the gateway

or electronic switching equipment in the 25 communications centers.

25.2. The creation of two dedicated network hub systems in strategically planned

locations to provide coverage to both the Northern and Southern regions of the

State utilizing an IP based network (LAN/WAN, Internet, the State digital

microwave system).

25.2.1. The dedicated network hub system for the Northern region would be

located at CHP Headquarters in Sacramento utilizing LAN/WAN

capabilities.


25.2.2. The dedicated network hub system for the Southern region would be

located at the Los Angeles Regional Traffic Management Center utilizing

LAN/WAN capabilities.

25.2.3. Dedicated network hub systems will utilize redundant LAN/WAN

capabilities to provide emergency connectivity.

25.2.4. The State digital microwave system will provide statewide connectivity to

the dedicated network hub systems.

25.2.5. Leased telephone line service will provide connectivity to the dedicated

network hub systems.

25.2.6. The dedicated network hub systems will provide future expansion

capabilities by linking two or more network hubs systems together.

25.2.7. Distributed network design to ensure continuity of local day-to-day

operations in the event of network failure. The design will utilize a

combination of the State digital microwave system and the CHP

LAN/WAN.

25.2.8. Provide future media capabilities (i.e., data and video) over an IP based

network.

25.3. The installation of additional electronic switching equipment to interconnect other

public safety agency radio systems when the CHP is required to have

interoperability with allied agencies during a major incident or disaster.

25.4. In areas where the CHP’s radio system coverage is not conducive for radio

interoperability, the use of the LAN/WAN, in conjunction with portable

gateway/switching equipment, may be used to provide connectivity.

25.5. The creation of a statewide 700 MHz radio system hub comprised of fixed base

station repeaters and gateway switching equipment. Primary locations will include

area offices and communications centers, but can vary depending on the

demographics and/or radio traffic volume. If additional locations are required,

allied agency sites, radio vault sites, and commercial facilities may be used to

provide the required area wide coverage.

25.5.1. The acquisition of additional 700 MHz frequency spectrum, 10 to 20

channels, will be required for the creation of a dedicated network hub

system (area, division, and statewide).


25.5.2. The creation of a dedicated network hub system to connect all area

offices in a division, and provide division wide tactical channel(s).

25.5.3. The utilization of a dedicated network hub system to connect divisions

and provide statewide tactical channel(s).

25.5.4. In areas that do not provide division wide coverage, supplemental 700

MHz base stations will be installed to augment the area office radio

system.

25.5.5. A monitoring system will be provided at the Sacramento Microwave

Center to monitor system status of the statewide 700 MHz radio system

hub.

25.6. The design and implementation of an interconnect or interface device to provide

remote access and control via CHP’s Rapid Response Vehicle/Incident Command

Vehicle (RRV/ICV) and other mobile command platforms utilizing the internet,

LAN/WAN, or satellite system.

25.6.1. The design and implementation of an interconnect or interface device for

remote access and control via the RRV/ICV and other mobile command

platforms to provide connectivity to the JPS ACU-1000 interoperability

gateways at the 25 CHP communications centers.



platforms to provide connectivity to the two dedicated network hub

systems in both the Northern and Southern regions of the State.



platforms to provide connectivity to the 700 MHz radio system hub.



platforms to provide connectivity to the State microwave system. Use of

the State microwave system will provide connectivity for future

enhancements and/or provide backup capabilities.



platforms to provide future connectivity to other first responders’


interoperability networks. These systems may be a combination of

established or ad-hoc interoperable systems used in the event of a major

incident or disaster.

26. Future Wide Area Network (WAN) Connectivity

26.1. One of the goals of the CHPERS project is to connect all CHP offices and

commands together with a VoIP communications capable WAN system.

26.2. The CHPERS Unit and CHP-TS will coordinate with CHP’s Information Technology

Section (CHP-IT) in order to upgrade and enhance the existing CHP WAN system

to be VoIP communications capable.

26.3. It is anticipated that the existing CHP WAN system, as it grows and becomes more

capable, in the future may be expanded to include remote radio sites for direct

control of radio base stations via the WAN.

26.4. If desired, the capability of newer digital audio logging recorders can be used to

record audio traffic of any radio channel connected to the WAN.

26.5. If possible, the CHP WAN may be connected to the State digital microwave system

depending on system compatibility and network security.

Notes: Frequency Coordinator: PP - Police PO - Forestry Conservation PX - All except Special Emergency PH - Highway Maintenance 1. A number "1" in a cell indicates the frequency of the corresponding column is potentially available for use in a CHP Area. 2. Use of a Mobile-Only frequency as a base transmit talk-out frequency will require a FCC waiver. 3. Database of potentially available frequencies upon which "Preliminary Low Band VHF Talk-Out Frequency Assignments by CHP Operational Areas" (dated 11-22-2005) is based. Number in a cell indicates those CHP Areas whose closest boundary is greater than 75 km from the interference contour of sites of all existing FCC licensed users -- interference contour defined by FCC R-6602 (Carey) Interference contour.
