4 Environmental Capabilities

The purpose of this chapter is to specify the environmental capabilities for RBS2301, RBS 2302, RBS 2401, Coverage Extension Unit and Active Antenna Unit.

4.1 ScopeThis chapter describes the environmental capabilities for the indoor andoutdoor temperature non-controlled operation conditions. Subjects includedare: climatic, biological, and chemically active substances; mechanically activesubstances, and mechanical conditions.

The capabilities cover the base station excluding installation and adjacent partsas antenna and earth connectors.

Note: The names of the various climate classes in the following section arefor classification purpose only and are not intended to limit the useof the products.

4.2 TerminologyDefinition of concepts:

Normal Operation Conditions

Environmental conditions where all units shall be able to function as specified.

Safe Function

Environmental stress above the limits for normal operation where all unitsshall continue to function during the stress, but performance or capacity maybe reduced.

Reduction of performance or capacity shall be documented as typical value.

When the environmental stress has dropped to normal operation conditions,function as specified shall automatically be achieved.

Safe function refers to an operation period of not more than 72 consecutivehours, and a total of not more than 15 days in one year.

Non-Destruction

Environmental stress above the limits for safe function during which no functionis guaranteed and performance may degrade in an unspecified manner.

11EN/LZT 720 0041 Uen R2B 2005-12-15


When the environmental stress has dropped to normal operation conditions, nomanual intervention (on site) is needed to restore full performance of the RBS.

Non-destruction refers to an operation period of not more than 96 consecutivehours, and a total of not more than 5.5 days in a 3-year period.

GSM Concepts

The GSM concepts for Normal operation and Extreme operation conditions asdefined in GSM 11.20-12.3.2 are both equal to the Normal condition as definedand used in this document. This means that all RF parameters are guaranteedwithin the Normal condition range as defined in this document.

5.3.1 General

AC/DC loss

• Calculated with an RBS PSU efficiency of 81% on the AC/DC converter,and a PBC PSU efficiency of 83%.

Back-up time

• The back-up time is measured on one configuration. The result of themeasurement is used to calculate the theoretical back-up time for all otherconfigurations.

DC/DC loss

• Calculated with a PBC PSU efficiency of 84%.

Cable loss

• Calculated for 100 m cable.

Maximum power consumption

• The heater is active in AC mode, trickle charge 10 W, text < –20 C. Theheater is not on when in battery back-up mode.

Nominal power consumption

• Based on nominal operation conditions. That is, the heater is off, tricklecharge 10 W, text = 20 C. Both transceivers are sending with full outputpower at 230 V nominal mains supply.

Trickle charge

• Charge of PBC during operation in AC mode.

6 Site Configurations, RBS 2000 Small Indoor

This chapter describes the site configurations which are possible using theRBS 2000 Small Indoor Radio Base Stations.

6.1 Terminology

AGW A gateway between UDP/TCP/IP traffic on Ethernet toA-bis (LAPD) traffic on an E1 interface to the RBS.

Far End Far End is a physical node in a network. It is the node inthe network closest to RBS (that is, not another RBS).The Far End referred to is different nodes within BSS,such as DXX, Mini DXC and BSC.

HDSL By use of HDSL transmission it is possible to connectthe RBS to physical twisted copper pairs from aBSC or transmission terminal for the A-bis interface.The distance can be longer than with traditional lineterminals.

RBS 2401 Small Indoor Radio Base Station

6.2 Site Configurations OverviewThe table below shows the possible site configurations for the RBS 2401 SmallIndoor RBS. The short number is a concise name for a given site configuration.

Note: Not all of the configurations possible are necessarily described with afigure.

7.2 Terminology

7.2.1 The Mobile Telephone System

Figure 31 RBS 2000 in Ericsson’s GSM System

The BSS (Base Station System) contains two functional entities:

• The BSC (Base Station Controller) handles the radio-related functionssuch as hand over, management of the radio network resources, and cell

configuration data. It also controls radio frequency power levels in basestations and mobile stations.

• The BTS (Base Transceiver Station) is the radio equipment needed toserve one cell. It consists of the antenna system, the radio frequencypower amplifiers and all the digital signal processing equipment. RBS 2000contains equipment for one to three BTSs.

7.2.2 Antenna System

The antenna system is constituted by all RF transmission and receptionantennas, directed to cover the same area or multicasting configuration.

Antenna Reference Point (ARP)

Two ARP are defined in this document; the RBS ARP and the AAU V (1) -ARP.

The RBS ARP is the feeder connector on the RBS.

The AAU V-ARP is the test connector after the network that connects theoutputs from different PAMs. This network is used for test purposes only.

(1) V=Virtual

58 EN/LZT 720 0041 Uen R2B 2005-12-15


Active Antenna Unit (AAU)

The Active Antenna comprises two separate physical RF channels whichinclude LNAs and PAs.

The AA is a unit where the LNAs and PAs are integrated with the antennaelements.

7.2.3 Basic Configuration

A maximum of two transceivers can be combined and connected to oneantenna system.

The basic configuration may be multiplied or used in combination with otherbasic configurations to build the needed site equipment.

7.2.5 Site/Cell Configuration (SCC)

This is a geographical concept that describes how an area around one radiobase station site is divided into radio traffic areas.

7.3 Frequency BandsThis section describes the uplink and downlink frequency bands used forGSM 900, GSM 1800, and GSM 1900.

GSM 900 Uplink: 890 – 915 MHz

Downlink: 935 – 960 MHz

59EN/LZT 720 0041 Uen R2B 2005-12-15


GSM 1800 Uplink: 1710 – 1785 MHz


GSM 1900 Uplink: 1850 – 1910 MHz


7.4 GeneralRBS Configurations is the designated expression for the RF parts integrated inthe BTS.

The functionality is:

• The output signal from one or more transmitters are combined into thesame antenna system, which can be utilized as a TX/RX antenna.

• The received signal from the receive antenna system, which can be utilizedas a TX/RX antenna, is distributed to receivers belonging to one RBS.

7.5 Configurations

7.5.1 TX Output Power

The value given for the RBS output power for the different configurations belowis the minimum RBS output power when the transmitter is set for maximumnominal power (P0).

The RBS output power is measured at the TX reference point, and it isdependent on the TX combining and filtering parts.

The tolerance for the RBS output power at the different settings is in compliancewith /GSM:05.05:4.1.2/ for GSM 900 and GSM 1800, and /PCS:5.3.3/ forGSM 1900.

When two or more transmitters are combined to one antenna, the transmittersmust be operated with a minimum of 400 kHz separation between the centrefrequency of adjacent carriers. This limitation is not caused by the combinerbut the RBS itself.

With TX diversity configured both transmitters use the same ARFCN.

The maximum nominal power, P0, measured on the cabinet output RFconnector (which in this case corresponds to the TX Reference Point) isminimum +32 dBm. This output power level is valid for all frequency bands.

60 EN/LZT 720 0041 Uen R2B 2005-12-15


With TX diversity configured, the output power is minimum +32 dBm at eachARP.

If an AAU configuration is used, the maximum nominal power, P0, defined asthe EIRP measured in the far field, is minimum +55 dBm for the AAU 500 W and+59 dBm for the AAU 1250 W. (The EIRP can be calculated to correspond to aequivalent RF power before transferring to the integrated antenna elements.)

Nominal A-bis configuration power parameters for the Micro Base Station RBS2301:

900 MHz 21 – 33(dec)

1800 MHz 21 – 33(dec)

1900 MHz 21 – 33(dec)

Note: Only steps by 2 is configurable (from the highest value).

TX diversity configuration power parameters for the Micro Base Station RBS2301:

900 MHz 35(dec)

1800 MHz 35(dec)

1900 MHz 35(dec)

7.5.2 RX Description

The receiver system performance is dependent on the configuration.

Actual Sensitivity Level

The actual sensitivity level is defined in and complying with the level where RBSmeets the reference sensitivity performance defined in:

- /GSM:05.05:6.2/ for GSM 900 and GSM 1800

- /PCS:4/ and /PCS:5.1.1/ for GSM 1900.

Radio Reception

The receiver sensitivity is reduced when a third order intermodulation product,generated by the radio transmitters in the RBS, is received at the same RCFNas the useful signal.

This occurs when the distance in frequency between two simultaneoustransmitters is chosen in such a way that a third order intermodulation product

61EN/LZT 720 0041 Uen R2B 2005-12-15


is generated at the same frequency as the operating frequency of one of thereceivers in the RBS.

Note: In RBS 2301 the receiver sensitivity will be decreased by 1 dB when athird order transmitter intermodulation product coincides in frequencywith an active frequency used by the receiver.

7.5.3 Isolation Values

Minimum isolation requirements between two antennas belonging to the sameRBS are as follows:

- for GSM 900: 15 dB

- for GSM 1800 and GSM 1900: 20 dB

- for Maxite, GSM 1800 and GSM 1900: 30 dB

7.5.4 Omnidirectional Antenna

8 Radio Configurations, RBS 2000 SmallIndoor

This chapter describes the basic configurations which are supported for SmallIndoor RBS.

8.1 References/GSM 05. 05/ GSM Requirements 05. 05 phase 2+

8.2 TerminologyAntenna ReferencePoint (ARP)

The ARP is defined as the point where the RX/TXantenna signal crosses the RBS border, that is, theconnectors for the antenna connection.

Antenna System Is constituted by all RF transmission and receptionantennas and directed to cover the same coverage area.

BasicConfiguration

The RBS has multicasting configuration only, that is,both TRXs are available at both antenna ports.

The basic configuration can be used in cascade(multidrop) configuration.

Site/CellConfiguration(SCC)

Is a geographical concept that describes how an areaaround one radio base station site is divided into radiotraffic areas.

8.2.2 Site/Cell Configuration (SCC)

The SCC is a geographical concept that describes how an area around oneradio base station site is divided into radio traffic areas.

8.3 Frequency BandsGSM 900 Uplink: 890 - 915 MHz

Downlink: 935 - 960 MHz

GSM 1800 Uplink: 1710 - 1785 MHz

Downlink: 1805 - 1880 MHz

8.4 GeneralRBS Configurations is the designated expression for the RF parts integratedin the BTS. They consist of transceivers and CDU.

The CDU functionality is:

• The output signal from the two transmitters is combined into the sameantenna system, which is utilized as a TX/RX antenna.

• The received signal from the receive antenna system, which is utilized as aTX/RX antenna, is distributed to receivers belonging to the RBS.

• Multicasting functionality, see Section 8.5.3 on page 85.

8.5 ConfigurationsThis section describes the major parameters for the basic configurations thatare supported for Small Indoor RBS.

8.5.1 TX Output Power

Small Indoor RBS TX power complies to:

GSM:05. 05 ClassM2

GSM 900

GSM:05. 05 ClassM3

GSM 1800

The value given for the RBS output power for the different configurations belowis the maximum RBS output power when the transmitter is set for maximumnominal power (Po).

84 EN/LZT 720 0041 Uen R2B 2005-12-15


The RBS output power is measured at the ARP.

The tolerance for the RBS output power at the different settings is in compliancewith /GSM900:05. 05:4.1.2/ for GSM 900 and GSM 1800.

Since the two transmitters are combined to one antenna, the transmittersmust be operated with a minimum of 400 kHz separation between the centrefrequency of adjacent carriers. This limitation is not caused by the combinerbut the RBS itself.

The maximum nominal power, Po, measured at ARP is:

• Nominal 19 dBm P-GSM 900

• Nominal 22 dBm GSM 1800

Nominal A-bis configuration power parameters for the Small Indoor RBS:

900 MHz: 07 - 19(dec)

1800 MHz: 09 - 21(dec)

Note: Only steps by 2 are configurable (from the highest value).

8.5.2 RX Description

The receiver system performance is defined in the ARP.

Actual sensitivity level is defined in and complying with the level where RBSmeets the reference sensitivity performance defined in /GSM:05. 05:6.2/ forGSM 900/GSM 1800.

Radio Reception

The receiver sensitivity will be reduced when a third order intermodulationproduct, generated by the radio transmitters in the RBS, is received at thesame ARFCN as the useful signal.

This occurs when the distance in frequency between two simultaneoustransmitters is chosen in such a way that a third order intermodulation productis generated at the same frequency as the operating frequency of one of thereceivers in the RBS.

8.5.3 Multicasting Function

Small Indoor RBS has multicasting functionality only; that is, the two TX and RXsignals are present at both antenna ports. This means that either one or twoantenna systems may be connected to the RBS. If only one antenna system isconnected, then the other one is terminated into a load of 50 .

85EN/LZT 720 0041 Uen R2B 2005-12-15


8.5.4 Isolation Values

The minimum isolation requirements between two antenna systems belongingto the same RBS is 15 dB, if the antennas do not have different polarizationdirections or different coverage areas.

8.5.5 Limitations

RX-diversity is not supported.

TX-diversity is not supported.

Use of LNA or booster is not supported.

Frequency planning to avoid IM3–interference into its own receiver has to bedone. See section Radio Reception.

Small Indoor RBS shall not be co-located with or placed within 100 m of aMacro RBS, if free space propagation conditions exist.

12 Climate Protection

The "Climate Protection" function:

• Supervises and maintains the internal temperature within allowed rangesfor the units in the RBS

• Controls the connection and disconnection of power, at start (or restart)of the RBS and at extreme internal temperature.

The external temperature range for each RBS type is product-specific. To geta complete picture of the climate protection system’s capacity, this documentshould be read in conjunction with the relevant product specification.

The Climate Protection of an RBS can be maintained with one or a combinationof the functions described in this chapter.

12.2.5 Power Connection

At start and restart of the RBS, the connection of the RBS power system to theincoming AC mains and the connection of the users to the DC power in theRBS depends on the current internal temperature.

There are a number of start up scenarios, based on the internal temperature atthe moment of startup:

• The internal temperature is within the safe range.

126 EN/LZT 720 0041 Uen R2B 2005-12-15


− The RBS power system and the users are connected.

• The internal temperature is below the lower limit for safe function.

− The internal temperature is increased by heating to above the lowerlimit for safe. Then the power system and the users are connected.

• The internal temperature is above the upper limit for safe function.

− The RBS power system is connected but the users are not. However,as soon as the internal temperature falls below the upper limit for safefunction, the users are connected.

12.2.6 Power Disconnection and Reconnection

Users are disconnected from DC power when the internal temperature isoutside the safe range.

When the internal temperature is back within the safe range, the users arereconnected to the DC power.

HDSL - High bit rate Digital Subscriber Line Modem

The HDSL modem is an optional transmission module, mounted in an extendedinstallation box door. It replaces the original door on the mounting base. Itincreases the width of RBS 2302 by 35 mm.

By using the integrated HDSL modem it is possible to connect the RBS 2302to BSC (Base Station Controller) with HDSL equipment at BSC site and/or toanother RBS 2302 with HDSL. The distance can be longer than with traditionalline terminals. The need for repeaters is thus reduced, which means lowertransmission costs. This makes the installation easier and the sites will be morelandlord friendly due to integrated solution.

The HDSL modem uses two of the external alarms. These alarms are definedby setting of a switch on the HDSL modem.

A conventional gain antenna contains a number of passive elements in an array,that focuses the antenna beam in the desired direction. The active antennauses amplifiers to further increase the gain. The Antenna Passive Unit (APU) ofthe AAU is consists of a patch antenna array.

Antenna diversity is built into the AAU. The traditional method of diversityreception is to use two antennas horizontally spaced. The AAU uses anotherdiversity method: dual polarization diversity. Two antennas are housed in theunit. The AAU contains two antenna arrays, one with +45 polarization and theother with -45 polarization. RX diversity is obtained between the two arrayswhen they are connected to separate RX ports.

The Antenna Electrical Unit (AEU) is the active part of the AAU. The AEUworks in duplex mode. TX and RX signals are separated with a duplex filterand a circulator. The RX signals are amplified through one Low Noise Amplifier(LNA) per RX path.

The TX part consists of Power Amplifier Modules (PAM). Each module containstwo amplifiers, one for each TX channel. A number of PAMs are connected todifferent parts of the passive antenna array so that one faulty PAM only causesa small deterioration in performance. The AEU is also equipped with DC/DCconverters for power distribution and alarm and control circuits.

The AAU passive antenna has the following characteristics:
