INTRODUCTION AND SUMMARY

The FCC has asked for entities to submit proposals to operate a database to satisfy

the FCC's rules for providing a data repository, a data registration process, a query

process and a fee collection process to allow authorized devices to use the television

"white spaces" to provide services. To this end, the FCC has asked entities to address

five points:

1. The entity possesses the technical expertise and real world experience to

administer a TV and database and can prove it can operate the database for the

five-year term established in the FCC rules;

2. The scope of database functions to be performed, and how data might be

synchronized between multiple TV band database administrators, if multiple

administrators are authorized;

3. The architecture and description of the functions of the system;

4. A description of data transfer mechanisms; and

5. A description of how TV band devices will communicate with the database,

including security methods.

The KBE/LS team is uniquely qualified to provide these services and administer a

TV band database. KBE founder Karen Wrege was the program manager for the

conceptualization, design and development of the FCCs Universal Licensing System,

and both principals have expert knowledge of the FCC licensing and rulemaking

processes. While KBE's experience in this area is significant, the company founders

were interested in not recreating the wheel when developing the TV band database.

Instead, they investigated the world market for the leading off-the-shelf spectrum

management software provider to partner with who could use its existing tool set and

customize it to fully meet the FCC requirements. LS telcom has been in business since

1992, with their origins in broadcast network planning and now provides spectrum

management database tools in over 75 countries around the world. Both firms are well

established and have a proven track record of system and database development and

management.

Beginning in 1992, LS telcom has developed a complete suite of tools for Spectrum

Management which is used all over the world by public, military and private regulators

for the purpose of granting Spectrum access to its customers on a open and nondiscriminatory basis while ensuring also the efficient and economic use of the limited

resource spectrum. With the LS suite of technology, all necessary elements to build,

operate and further refine the database are available as COTS to meet the FCC's stated

requirements. The KB/LS team has a strong group of experienced analysts, developers

and engineers capable providing the best solution for the US market from these

components.

The KBE/LS team plans to perform the entire set of database functions required by

the FCC including data repository functions, data registration, calculation and query

functions, and fee collection, and will work with other TV band database administrators

to synchronize data on a regular basis.

In our technical proposal, attached, we provide details on the architecture, functions

and methods employed in the system.

1 About KBE and LS telcom

1.1 Introduction

KB Enterprises LLC and LS telcom (KBE/LS) hereby submit their comments on the

Office of Engineering and Technology Public Notice (PN) inviting proposals from entities

seeking to be designated TV band device database managers. The KBE/LS team have existing

solutions that meet many of the requirements set forth by the FCC, and have the expertise,

skills and ability to further modify and enhance its existing software to implement the proscribed

TV Band Database in the United States. In the following sections we will lay out our

qualifications and details of our solution.

1.2 KBE

KB Enterprises LLC (KBE) is a consultancy providing telecommunications policy

consulting as well as spectrum auction design and software implementation. KBE's founding

partners Karen Wrege and Brett Tarnutzer together have over 36 years of experience in

telecommunications policy and spectrum software systems development. Their experience in

telecommunications began within the FCC and more recently they have worked for wirelesstelecommunications companies and government regulators around the world providing software

solutions and tools for companies and regulators for spectrum assignment. Notably, KBEs

founding partner Karen Wrege was the program manager of the conceptualization, design and

development of the FCCs Universal Licensing System (ULS), and has a deep and rich

understanding of the FCC licensing data and fee collection processes and systems. KBE has

expertise and experience managing complex database development projects in and for the

Federal sector and has significant experience merging data from multiple, disparate data

sources into a single database. While KBE's experience in this area is significant, the companyfounders were interested in not recreating the wheel when developing the TV band database.

Instead, they investigated the world market for the leading off-the-shelf spectrum management

software provider to partner with who could use its existing tool set and customize it to fully

meet the FCC requirements.


9/109




1.3 LS telcom

LS telcom AG (LS telcom) is the worlds leading vendor of spectrum management

solutions supporting more than 75 countries worldwide. LS telcom was founded in 1992 as an

engineering company focusing on radio network planning. Its founders, Dr. Manfred Lebherz

and Dr. Georg Schne, both worked in the Institute for Microwave Technology (IHE) at the

University of Karlsruhe/Germany for several years, where they developed wave propagation

models and radar measurement technologies.

LS telcom is the only company that offers a complete portfolio of software, strategic

consulting, training and engineering services addressing the efficient use of radio frequencyspectrum and ensuring the most optimal operation of radio communication services. What

started as a niche market engineering company is now a highly professional group of

companies operating on a worldwide scale in consultancy, system integration and software

supply. Over the past 18 years, LS telcom has grown to over 118 employees in 6 countries.

The LS telcom Group is today comprised of LS telcom AG Germany, LS telcom SAS France

(former Spectrum Management Division of CTS International), LS telcom Limited Canada

(Spectrocan), LS telcom Hungary, LS telcom Oman, and LS telcom of South Africa.

As a company dedicated to the supply of spectrum economy solutions and as amanufacturer of spectrum management software, LS telcom has become internationally

recognized in radio network planning and spectrum management, and has successfully

implemented spectrum management systems for numerous regulating organizations in

countries with extremely high telecommunication standards.

LS telcom operates on the basic premise that, beyond the delivery of advanced

automated systems, we also deliver appropriate operational expertise, technical support, and

training. This philosophy has been the cornerstone of its success regardless of project

complexity, scope, and size. LS telcom is a strong proponent of long-term human resource

development programs to ensure its clients are provided with expert staff for the length of the

project. LS telcoms commitment to knowledge transfer is reflected in the various

telecommunications institutions they are active in (as listed below), as well as on numerous

training projects and seminars that they conduct for their staff and clients.


10/109




With its global operations and partnerships, LS telcom has a detailed knowledge of the

local Information and Communications Technology (ICT) environment as well as the processesand procedures required for successful consultation with local stakeholders. LS telcom

integrates their participation in a number of international organizations and study groups into

their approach, including:

Membership in the ITU Radio Communications Sector and the ITU Development Sector;

Membership in the Telecommunications Executive Management Institute of Canada

(TEMIC) and the Inter-American Telecommunication Commission (CITEL) Membership in the Broadcast Mobile Convergence Forum (BMCO), and

Close partnerships with many recognized research and development institutes and

universities, e.g. German Institute of Broadcasting (IRT), Canadian Research Center

(CRC)

Since it was founded in 1992, LS telcom has provided network planning software to

operators and spectrum management solutions to national regulators. In the past ten years, theLS telcom group has delivered over $100 million of solutions to regulators on every continent.

Today, LS telcom has over 75 national regulatory agencies as its clients throughout the world.

Over the years, LS telcoms team has invested hundreds of man-years of development in

spectrum management systems and radio network planning tools. Our Spectrum Management

System SPECTRAplus is based on the best practices and it is utilized by regulators throughout

the world, and has a proven track record. As shown in the following figure, the SPECTRAplus

system goes well beyond application processing and truly embodies all of the elements of a

complete and modern SMS system.


11/109




Features of the SPECTRA System

The SPECTRA system was designed in a modular fashion in order to create a solution

that can be tailored to each individual customer. In the case of the TV bands database, only the

relevant modules will be deployed, keeping the system lean, but allowing for the easy

integration of other modules in the future if rules, requirements or desired features change.


12/109




1.4 Technical and commercial experienceKBE/LS together possess the technical expertise and real world experience necessary to

develop and operate a TV band database, including the ability to sustain operations for the five-

year requirement.

As shown in the figure below, during the past two decades, LS telcom has developed a

complete suite of tools for spectrum management that are used all over the world by public,

military and private regulators for the purpose of granting spectrum access to their customers on

an open and non-discriminatory basis while ensuring the efficient and economic use of the

limited resource.

A summary of the existing capabilities and modules of the system can be found at the end

of this proposal. The summary shows that all necessary elements to build, operate and further

refine the TV bands database are already available as COTS products offered by LS telcom.

SPECTRA System Modules


13/109




The LS telcom groups strong team of analysts, developers and engineers has the proven

knowledge and expertise to develop and operate a secure, accurate and accessible TV bandsdatabase in the United States.

1.5 Our vision of the future of spectrum managementWith its decision to allow the use of white spaces in the TV band, the FCC has opened

the door to a breathtaking future for spectrum distribution. Through the networking of

communication devices, information services (databases), calculation services and interference

monitoring (as separate units or embedded in the communication devices), a completely new

dimension of possibilities is available. KBE/LS telcom is excited to contribute its experience in

the traditional Spectrum Management and implementation of complex, web-based database

applications to this future technology. The white spaces proceeding being undertaken by the

FCC is the first step to a new paradigm for future spectrum management.

The key to using white spaces is to detect unused spectrum. This can be conceived of in

a number of ways, either in the geographical dimension , as shown in the following example

from an LS telcom analysis of the digital services in Portugal:

The coverage of a DTV scenario in Portugal (differing signal strength indicated by red, orange andyellow) and the resulting white spaces.


14/109




In the frequency dimension , as illustrated in an analysis for Ofcom for locations within the UK:

Or in the time dimension , as shown below, which shows the time dependent usage of wireless

microphones:

Using white spaces in the time dimension

Once identified, devices can make use of these otherwise unused white spaces.

15/109




2 THE KBE/LS TV BANDS DATABASE

2.1 Required elements and payment schemes

The KBE/LS team is committed to fulfill all of the elements of the TV band database

requirements including, creating a fully secure and reliable database to act as a data repository,

performing calculations to determine available channels and registering fixed unlicensed

devices and licensed services not listed in the FCCs databases.

The KB/LS team is proposing to charge TV band devices a fee for initial registration with

the database with the option of annual or bi-annual renewal fees. We propose that the feeswould be collected in one of two ways. First, vendors could pre-register devices in bulk,

activating multiple serial numbers with a payment to the TV band database by wire transfer or

credit/debit card. Second, users could register a single device through a web portal or the

device itself and activate its serial number with a payment to the TV band database by wire

transfer or credit/debit card.

We understand that the FCC feels it is not appropriate to charge operators of licensed

services to register their operations as protected services in the database and we do not

propose to do so. We propose to charge unlicensed entities filing with the database for

protection (e.g., cable headends and TV translator/low power TV station receivers) a fee to

register the equipment or to make modifications to their registration, following the FCC's

application fee model. We will give these filing entities the option of filing and paying in a batch

process, or interactively via a web interface. Finally, another category of registrants may be

network operators who wish to register all of their network equipment with the TV band

database. We envision creating a frame agreement for registrations that encompass a

complete network and would allow the network operator to pay by check or wire transfer. All

access to the database and fees charged for the database will be on a non-discriminatory basis.

Our team possesses the skills and experience to implement the fee collection system.

KBE founder Karen Wrege was responsible for the implementation of the current Universal

Licensing System at the FCC where batch and interactive filing of applications and payments


16/109




were introduced for all wireless services in 2001. In addition, LS telcoms existing application

processing system has collections based software to compute and collect fees electronicallyand to match manually filed fees to electronically filed applications.

In summary, we envision providing flexible payment options, including:

Checks

Wire transfer

Credit/debit cards

Payment services (Paypal, Google payments, etc.)

2.2 The KBE/LS TV band database structureAs mentioned above, the KBE/LS TV band database functions and structure will support

all of the needs and requirements set forth in the FCC rules. The following diagram shows the

high level concept of the primary entities and data streams included in the database.


17/109




2.2.1 Structure of the database

LS telcom has developed a database structure that is optimized by radio service. The

figure below illustrates the high-level core data storage map for broadcast licenses.

The database is designed to contain technical, administrative, coordination, payment andstatus information for each entity. The database also includes workflow processing and

maintains complete histories for registration and renewal status.


18/109




2.3 The KBE/LS TV band database functionsThe major tasks that will be undertaken by the Band Database System are outlined below:

2.3.1 FCC Data Import and Update

The following data will be initially imported and instantly updated from various FCC

databases:

TV transmitters (full service and low power) from CBDS

Public Land Mobile Radio services and Commercial Mobile Radio Services from ULS

Regions served by the Offshore Radiotelephone Service from ULS

Fixed Broadcast Auxiliary Point-to-Point Services from ULS

This data will serve as the base for the analysis of available channels, and will be

augmented by additional data described below. The data will be retrieved from the FCC on a

nightly basis, and the TV band databases would benefit from the FCC providing a modification

file as part of its nightly batch processing to append the database on a nightly basis with the

updated information.

2.3.2 Licensed, non registered devices

The TV band database will support the registration of devices that are licensed by FCC

but are not available in the FCC databases via a web portal. These include:

Temporary Broadcast Auxiliary Devices (BAS)

Low Power Auxiliary Devices like portable microphones

Low Power TV stations and TV translators

Cable TV head ends outside the protection area of the related TV site

The database will capture the relevant data elements based on the specific requirements

set forth in the FCC rules and will include real-time edit checks to ensure data accuracy.


19/109




2.3.3 Data synchronization with other TV band databases

We understand the FCC will leave the details of data synchronization among multiple TV

band databases up to the administrators. It is our belief that in order to provide accurate data to

TV band devices and adequately protect incumbent users, it is necessary for the TV band

databases to have a defined handshake and timing schedule in place.

2.3.4 TV Band device access to database

Unlicensed TV band devices of a fixed nature or portable ones operating in Mode II need

to register with a TV band database to get information about free channels. To ensure TV band

database access only by type-accepted equipment, basic information (FCC ID and serial

number) will be stored during the registration process, when the vendor, producer or owner

initially registers the device with the database. When the device accesses the database to query

for available channels, it will transmit this information again for verification of registration. This

will serve as a security check. At that point, for mode II devices the devices coordinates

(latitude and longitude) will be submitted to the database to query for available channels. For

fixed devices, the users name and contact information must be submitted and will reside in the

database.

2.3.5 Reporting to FCC

The database will allow the FCC to access information about registered devices in order

to address potential sources of interference. As part of the TV band database system, KBE/LS

will implement a password protected FCC interface that will allow authorized FCC users to

query the database for available information by defined search criteria. The final functionality of

this section will be agreed upon with the FCC.

2.3.6 Enforcement of FCC decision to de-authorize a device

The FCC will have the ability to specify any device, make, or group of serial numbers

within a specific make, as de-authorized, such that it receives the message no channels

available when reconnecting.

o Registration of licensed services

o Specific database queries by FCC

The following figure shows the general system concept:

Given LS telcoms long and distinguished history developing spectrum management

systems, this functionality does not have to be developed from scratch, but is available in

existing LS telcom products. A short illustration of the LS telcom Special Coordination Tool

SPECTRA SC, is shown here:


22/109




SPECTRAsc coordination tool

2.4 Protection of TV stations and other servicesIn order to give rapid responses for any channel list request, the system will operate in two

steps: First, an analysis unit will calculate the impact of any new registration or modification,

and second, a query unit will run a compatibility analysis to check channel availability at a

specific location. The concept is based on a layering of the channels within a region (or fractions

of a channel, if in the future this is more granularly defined) as shown below. Initially, all channel

layers are empty. The following constraints are applied for every layer:

Border protection (distance criteria, frequency band)

TV station protection (according to FCC contours @ frequency)

PLMRS and CMRS protection (13 City centers plus registered auxiliary locations @

Frequency)

Offshore radio telephony service protection (contours @ frequency)


23/109




BAS and broadcast point-to-point services: (angle and distance @ frequency)

Low power auxiliary device protection (distance @ frequency)

Cable head ends (distance, angle, frequency)

Initial band scenario with no constraints applied: all frequencies available everywhere.

For a single channel, this could lead to a result as shown below: The green spaces are

still usable for granting access, while the colored spaces are blocked.

Constraints are applied for one device class at channel 23

As a result, the database will contain detailed contour information to be considered for all

available channels or sub-channels. It is then possible to quickly check for the availability of a

channel at a specific location. This contour information will be applied all of the various kinds of


24/109




devices including low power uses in adjacent channels. The analysis unit will continually

examine new entries and modifications to the database and determine their impact on the actualsituation in a specific channel /device class layer.

Final band scenario with all constraints applied: Only specific channels available at certain locations


25/109




2.4.1 Protection of contour based boundaries: General capabilitiesThe system is tailored to protect services and devices based on contour approaches

using given contour structures, e.g. provided as polygons. The following figure shows

protection zones for flight paths in the proximity of civil airports.

Protection of a glide path in the proximity of an airport

These contours may be very different in nature and the LS system is capable of

combining constraints ( e.g. use a specific contour at one frequency while using another contour

or no contour at all at others.) The system is programmable, allowing it to easily adapt to future

rule changes.

The system is able to calculate field strength contours according to the R6602 curves,

which are already embedded in the system. In addition, it has a powerful field strength and

interference analysis engine included for many other kinds of propagation models. It is able toanalyze co- and adjacent- channel interference and also desensitization and intermodulation

interference from and to more distant channels. Using the system, contour calculations can be

easily be analyzed for interference limited paths or for noise limited paths.


26/109




Analysis and consideration of noise or interference contours for a broadcast transmitter

Furthermore, the system has embedded modules for detailed terrain based analysis

using high level prediction models for field strength prediction and frequency dependent

rejection (FDR) for interference consideration in neighboring channel scenarios.

Best server consideration based on a detailed analysis with a model using topo and morpho


27/109




Analysis of interference from neighboring channels using FDR

In order to get the most accurate results, the system stores all propagation and

interference relevant information like Antenna Pattern, Filter Curves, Emission Masks and uses

either individual figures for a specific device or general data which has been standardized for a

group of devices or a whole service. For more general considerations and especially for the fast

analysis of contour scenarios, the system can also store and make use of effective heights and

effective terrain roughness.

Antenna Pattern in horizontal and vertical plane; also 3d diagrams may be stored and used


28/109




Effective heights for a TV transmitter

2.4.2 Protection of contour based boundaries: Specific tasks

The next section gives detailed information on the analysis methods applied in the TV

bands database.


29/109




2.4.2.1 Protection of Borders

The system considers the following border scenarios:

No TVBDs in 32 km distance to the Canadian border

No UHF TVBDs in 40 km and no VHF TVBDs in 60 km distance to the Mexican border


30/109




The borders are stored as polygons in the database, and the distant in-country lines are

precompiled in the database allowing for fast analysis.

2.4.2.2 Protection of PLMRS and CMRS services

Public and commercial mobile radio services must be protected at specific channels in

13 major cities in the US. These locations and the relevant protection circles at 131 and 134 km

are stored for comparison in the spatial sector of the database.

Protection of PLMRS and CMRS in major city centres; also protection of Ch.37

Protection of individually licensed PLMRS and CMRS


31/109




2.4.2.3 Protection of Cable TV head-ends, translator receivers and permanent

BAS Cable TV head-ends, translators and permanent BAS sites have a relation to a specific

feed station from where they receive their signals. If they are located outside the coverage

contour of the feed site, a keyhole protection, as explained in figure below, is applied. The

keyhole is processed once a station is registered in the database and will be considered when

compiling empty channels.

Protection of BAS, CATV head-ends and translator sites


32/109




2.4.2.4 Protection of Radio-Astronomy services

As Radio-Astronomy sites require high protection against man-made noise, it is

important to protect theses sites. Therefore, a of 2.4 km protection circle will be applied.

Protection of Radio-Astronomy Services

2.4.2.5 Protection of TV services

For TV services, the system calculates the coverage contours according to the table

given below. Therefore all facilities are included in the system and compilation takes only

fractions of a second.


33/109




Based on these contours, the following protection considerations are applied:

Protection of TV stations


34/109




2.4.2.6 Protection of Low power devices, including wireless microphones

Registered devices and sites will have a protection zone of 1 km from the site location.

These circles will be computed after registration or after receiving data or updates from another

TV band database and stored in the protected channel layers.

2.4.2.7 Protection of Off-Shore Telephony services

Off-shore telephony services will be protected along the Gulf of Mexico in the four

designated regions. .

2.5 Interfaces

2.5.1 TV band device communication with TV band database

There are two planned interfaces for communication between the TV band devices and the

TV band database. The are:

A web portal where the producer, vendor, or user of the device may register the device

for use and pay the fee for database access.

An interface for the TV band device to register at a given location to get an availablechannel list. The input and output will be standardized between the database providers

and other stakeholders.

2.5.2 Interfaces to the FCC databases

The database will connect with FCC databases to retrieve information no less frequently

than daily. As mentioned earlier, we recommend that the FCC create summary files of

modifications for the TV band databases to simplify the update process. We envision the FCC

putting the files on a file server than can be accessed by the TV band database managers to

download the files and update their databases on a daily basis.


35/109




2.5.3 Interfaces for other database operators

For communication and data exchange with other TV band databases we will meet and

agree on an interface structure. It will be critical to have rapid and efficient updating in order to

keep the data accurate and current. One means of doing this is for each database administrator

to continually update a secure change log so other TV band databases could access the

changes on a real-time basis. In addition, there will also be a need for a full download capability

to get the complete status for periodic database validation.

2.5.4 WEB portal for registration of BAS and other devices

All devices eligible for protection against TV band databases may register via the web

portal. In order to prevent abuse in filing and ensure that all devices are accurately represented

in the database, the FCC may want to consider requiring all unlicensed device users to first

obtain an FCC registration number (FRN) through CORES before registering with the TV band

database. Requiring an FRN when filing would help to prevent large-scale spamming that could

negatively impact the database accuracy and performance.


36/109




2.6 Database security

2.6.1 WEB security

The KBE/LS TV bands database will employ tested and secure methods to support

device communication and verification with the database. The system will contain several

Firewalls in order to protect the database content. Additionally, the communication between the

Interfaces and the actual database will only operate via web services in order to avoid direct

exposure to the internet. The following drawings show the basic construction of the interfaceand data streams between the outside world and the database.

General Structure of the Web interface protection.


37/109




Data streams from the outside world into the database.

2.6.2 Protection against data loss and server breakdown

The system is built with a redundant solution, using ORACLE Real Application Cluster

(RAC) technology to ensure a permanent availability of the central database system. The Web

servers also have redundancy components using load-balancing technology. The hardware

itself has redundant power supplies and Hot-Plug Raid solutions for data storage.

In addition, the system includes a hot backup facility so that the database may be

backed up while in operation. Backups of the database will be performed as differential backups

every night and full backups once a week.

1 SPECTRA System Professional Solution and General

System ComponentsThe ever increasing demand for frequency spectrum, generated to begin with the liberalizationand deregulation of the telecommunications market, and furthermore due to new technologies,services and changing life style - constant communication and information access everywhereat every time - confronts network providers and regulatory authorities constantly with newchallenges and requirements.

Licensing and frequency allocation processes have reached a maximum level of complexityowing to new technologies, services, and coordination activities going beyond national borders.Today, the scarce resource of frequency spectrum has to be assigned efficiently and without

delay. Expectations of license owners have risen in line with the high fees charged for lucrativelicenses. At the same time the end consumer expects high quality of service together withreasonable tariffs. Overall efficiency of spectrum allocation and use is vital to survive in a highlycompetitive market.

In order to address these challenges, LS telcom has developed a complete Software Tool SuiteSPECTRA Professional covering the whole range of spectrum management tasks:


44/109




1.1 General System Description

The SPECTRA Core Spectrum Management Configuration is based on the central SPECTRAspectrum management database and includes the software modules SPECTRAplus,SPECTRAplan and SPECTRAemc to cover all fundamental administrative and technicalaspects of spectrum management. The database stores and centralizes all license data, billingdata, technical data, monitoring data, frequency plans and ITU notifications.

The system is highly scalable: it can be used by a small number of users only, but also fulfils therequirements of very complex system arrangements for a multi-user multi-access environment.

The general system set-up is shown in the following figure.

Please note that this drawing should serve as a general overview only, and not necessarily all

modules and functions as presented in this figure will be included within the spectrummanagement system/database as planned to be used in the proposal. Nevertheless itdemonstrates, that this solution is capable of doing what shall be covered now plus everythingone may expect to be covered by such a solution in future..

All application, license and invoice processing tasks are carried out with SPECTRAplus. For strategic spectrum management including the administration of frequency plans and thehandling of policies and regulations, SPECTRAplan is the required module. The SPECTRAemcmodule is used for planning, coverage calculations, interference analysis and frequencyassignment.

The Core Spectrum Management System can be interfaced with radio monitoring systems dueto the MONITORplus interface. Another possible extension to the core system is the e-licensingsolution SPECTRAweb. SPECTRAweb can be applied in an online and offline mode.SPECTRAview is mainly used by staff without access to other SPECTRA tools. It allows accessto the central database using standard GIS functionality for visualisation purposes.

Furthermore, it is possible to extend the core system with technology specific radio planningand coordination modules according to particular needs.

1.2 Functional Description

1.2.1 Basic Administrative Functions

Basic administrative functions of the system are application, license and fee processing.Automated application processing includes checking that all required information has beenprovided and that other conditions e.g. spectrum availability are fulfilled. Once this is the caseand all fees are paid, a license may be ready to be issued.

The licensing function not only supports issuing of new licenses, but also renewal andtermination of existing licenses and other numerous administration capabilities. Licenseprocessing including printing of specific license forms is supported for all relevant radio servicesand sub-services. A deadline management and full workflow control supports the user inefficiently carrying out his day-to-day work.

An integrated billing module allows for comprehensive bookkeeping and service-specific feecalculation. Fee processing includes fee schedule maintenance and automated invoicegeneration.

Besides these basic functions the system supports a variety of other administrative activitiesfrom complaint processing to the generation of standard reports and administration-specificreports including vast statistical and management reporting capabilities. Other administrativefunctions and some details on the technical realization are described in the chapters further below.

1.2.2 Database Management

A decisive first step when implementing a spectrum management system is always to migratethe customers data towards a new, ORACLE based solution. Also all the data records have tobe analysed each one in particular to find out, whether the database entries are plausible, stillvalid and include sufficiently complete information as required by nowadays IT methods inspectrum management. This will reduce the amount of work for data integration significantlyonce a Spectrum Management System will come into operation.

While some of these works (in particular the validation with reality) is something that theCustomer need to carry out with its local expertise and knowledge about its licensed spectrum,there are also automated methods applied throughout the data migration process to checkplausibility and completeness of information, and where appropriate to fill missing information bycertain default values in accordance to pre-agreed rules.

For double checking data at the initial stage but also as an important measure for later datamaintenance here are standardised import/export interfaces included which allow to approach

data material of the ITU and to generate requests towards ITU and other internationalorganisations. These interfaces are permanently adjusted when required so that users under


47/109




maintenance will always benefit from new available data sources in order to feed the Softwarewith additional information like antenna patterns, Satellite data or newest coordination data.

Data from the existing Customers database will be collected, evaluated, where requiredcorrected and if possible also completed, and finally mapped and imported into thecomprehensive data model of the central SPECTRA database.

Exemplary database structure -1

The internal data structure of the central SPECTRA database is very complex andcomprehensive, in order to incorporate data of such different radio services like FM Broadcast,communication satellites, land mobile or fixed radio link services. Besides the technical structureof a single device like a TX or an RX also complete networks can be combined into oneapplication, consisting out of many sites at different locations, multiple equipment at each siteusing multiple frequencies at dedicated antenna patterns.



48/109




Links with one to one relations between receivers and transmitters can be described as well aspoint-multipoint structures or single components.

Besides this technical structure, also organisational information like postal addresses, thenames and reach-ability of responsible persons for a site or the owner information for sites/networks are stored. Ownership can even be shared between more than one persons or entities.

Administrative data is also kept in order to track processes like request letters or due dates.


In addition, a whole subsection is only responsible for the charging of frequency usage, whichmay be useful to create billing notes towards internal users to make them aware and sensiblefor a responsible usage of the spectrum resource. Also it may be used in future for 3rd partysublicensing, once such procedure is allowed by the regulator.

Together with the extension SPECTRAplus_bill, the database handling tool includes a powerfulbilling module. SPECTRAplus_bill incorporates fully featured fee calculation, invoicing and

accounting functions. Based on user configurable cost categories, billing strategies for e.g. costper channel or bandwidth can be set up. Fees can be altered at any time for a specific serviceor sub-service, or also for a specific license case where necessary. Automated fee calculationcan be done service-specific.

The included invoicing module allows to raise invoices based on the calculated fees and totrace their payment. If alterations of such a process need to be done, this is possible under theprocess customisation of the system. The billing functionality includes the creation of invoices,credit notes, reminders, manual bookings, the entry of payments and the trace of paymentbehaviour. Of course, the adoption of client-specific needs regarding fee calculation and book-keeping mostly requires extensive customisation.


49/109




In order to maintain license data and enter new license applications for stations or networks,SPECTRAplus_admin offers several methods:

Exemplary data entry mask -1

Inside the SPECTRAplus_admin application, the user is capable to enter data for all possibleservices. Dependent on the service type, which may be selected at the start of the entryprocess, SPECTRAplus_admin generates the appropriate data structure and offerscorresponding, specialized data entry dialogs. Because of the possibility of a powerful workflowcontrol, these data may be coupled with complex actions based on the process step and thedata content. Not all data have to be entered at the beginning; the information can be completedstep by step as it becomes available to the user and considering the users role andauthorisation. So the user could e.g. start only with some administrative information about therequesting organisation part, the person in charge and the structure and type of the network.


50/109




Exemplary data entry mask -2

Time by time, while technical investigations are carried out, more information can be fed to thesystem about equipment, antenna pattern, links and so on.

While ensuring outstanding performance in a multi-user environment the RDBMS offersadvanced security measures. An access control prevents from unauthorized data manipulation.Using a highly flexible data model main data types stored in the central database are:

! Administrative data

! Technical data

!

Frequency allocations! Monitoring data

1.2.3 Description of the Licensing Process

The proposed SPECTRA system solution is capable to handle and process licenses onnetwork, station or frequency level.

The processing of a license application can be done along different business processes thatmight be different for different radio services or license products. An exemplary process is givenin the picture below involving different departments and tasks.


51/109




The licensing process can be done completely within the proposed SPECTRA solution.

Typical steps that might be included (not necessarily all) in the different business processes for each license product could be:

- New Application Data Entry by the user

- Print Application Receipt

- Technical Analysis via generic EMC analysis or dedicated, radio service specifictechnical analysis modules (e.g. for broadcast, radio links, satellite, land-mobile).

- Spectrum Monitoring data gathering, obtaining reference field data (e.g. occupancy) tosupport the frequency assignment process. Besides the respective monitoring interfaceand functionality can also be used to support complaints processing and spectrum

control / enforcement processes. A monitoring interface is available to all relevantcurrent market radio monitoring systems for the control of the spectrum use.

- Load Channel Arrangement to cross-check the feasible assignment options with thenational frequency plan.

- Frequency Assignment

- Interference Analysis

- National Coordination

- International Coordination

- ITU NotificationFrequency Assignment, Interference Analysis, National and International Coordination as wellas ITU Notification will be done via our technical analysis modules. To simplify the users dailywork LS telcom has implemented a state-of-the-art wizard technology into the generic technicalanalysis module SPECTRAemc. These wizards can be user-defined and be executed fully- or semi-automatically allowing to run complex tasks in a manual semi-automatic (user interacts atsome steps) or full automatic mode.

- Fee Calculation. Fees can either be calculated by the standard fee calculation functionsincluded within SPECTRAplus, or by an external fee-calculation module. Our systemsolution offers also, as a matter of an optional extension and/or customisation, thepossibility to interface to and interact with third party Finance Systems, e.g. SAP, for accounting, payment collection and controlling purposes.

- Print Proposal

- Issue License


52/109




Exemplary Process

Furthermore the proposed SPECTRA system solution is capable to handle and processlicenses on network, station or frequency level. Irrespective of which licensing approach is takenby the customer a wide range of functionality is supporting the respective licensing process.

Licenses can be issued differently for different radio services depending on the character andspecifics of the respective license products, e.g.:

- licenses manually issued

- licenses issued for network, station or frequency- licenses granted on a temporary basis only or multi-year time limited with regular

renewal

- licenses granted for a fixed location or on an area defined basis.

An integrated deadline manager and full workflow control supports the user in efficientlycarrying out his day-to-day work.

The administrative spectrum management modules cover application processing including dataentry, plausibility and compliance checks, coordination procedures, report printing etc.

The licensing process handling includes but is not limited to license issue, printout andrenewal/variation/cancellation of licenses, fee-calculation, invoicing, and many more tasks.


53/109




The administration may vary from country to country taking into account internationalcoordination and specific regional multi-lateral co-operation and special coordinationagreements, ITU recommendations, international and national legal frameworks.

LS telcoms spectrum management system SPECTRA provides a comprehensive centraldatabase solution with versatile data querying and reporting capabilities for all needs of application processing and licensing as well as for management information, e.g.

- printing of licenses: different license formats for different radio services can beimplemented and be printed out; printing functions comprise client-specific forms likelicensing and invoicing forms and many others such as printing of selected records in atable (e. g. open invoices, open reminders, licenses to be printed, technical details of transmitters etc.)

- technical amendments or invoice documents

- a variety of statistical evaluations reports as for the statistics of use

- certification

- licensing

- invoicing

- printouts of selected stations on a map or tables containing the queried stations and their key parameters

- number of issued licenses

- amounts of collected fees

- list of all licensees or certifications of the past period

- quarterly or annual reports

- number of complaints, number of jobs performed

- license withdrawals or refusals and others

- printing of complaint acknowledgement

- printing of complaint resolution report and

- ITU approved standard form sheets for international coordination such as various APforms.

The system exceeds by far the corresponding ITU design guidelines for spectrummanagements systems. It fulfils and exceeds the minimum functional requirements of the ITU-Rrecommendation SM.1370-1, such as:

- License application data entry and processing

- License application administration

- Licensing

- Vendor/dealer recording

- Radio operator certification


54/109




- Equipment recording and notification

- Frequency selection- Technical analysis

- Coordination

- Inspection and interference complaints

- Monitoring system interface

The proposed SPECTRA system solution is capable to support all relevant life-cycles of a radiolicense once issued. i.e. renewal, variation and termination by either surrender or cancellation.For each of these different cases specific standard business processes have beenimplemented, assuring a consistent processing of such license status modification within thesystem. This means that e.g. fees or fines are consistently calculated; the database isappropriately updated to consider any such change in future technical analysis andadministrative licensing processes.

Along with the core functionality to support these license life-cycle-related processes alsoappropriate archiving functions are implemented, assuring that the life-cycle of a license isappropriately logged in the system and can be retrieved for any later prove purpose.

An integrated deadline manager and workflow control assures that the user can efficiently carryout his day-to-day job while not missing any relevant deadline.

1.2.3.1 Spectrum Planning

Generation and administration of frequency plans including channel allotments is done by our spectrum planning tool SPECTRAplan. Besides the client specific frequency plans that can beimplemented, SPECTRAplan also incorporates the ITU Frequency Allocations as standardconfiguration. It also provides functions to import data from the International Frequency List onCD-ROM and from the ITU Radio-Communication Information Circular/Local Frequency List.The SPECTRAplan module incorporates facilities for maintenance of frequency band channelallocations, descriptions and footnotes. It can even perform various channel calculationprocedures and allows to graphically displaying the frequency allocations.


55/109

SPECTRAplan supports the selection of free/occupied frequencies based on frequencyallocations and channel allotments according to ITU RRS5 / WRC2000/2003/2007 and user defined frequency plans. Free/occupied frequencies can be visualized in 2D charts and inspreadsheets.

In terms of governance for the management of spectrum the system offers:

- definition and use of particular frequency plans as described above

- entry of user defined footnotes for each channel

- blocking and reservation of channels for assignment

- specification of numerous default values in the frequency assignment process (e.g.thresholds, search range of interferers etc.) which can be modified by special user rightsonly, to ensure consistent calculation and frequency assignment results.

1.2.3.2 Electromagnetic Compatibility Analysis

All basic calculations that usually have to be done by regulatory authorities are supported by thebelow described tools. The functionality also covers inter-service analysis for shared bands e.g.potential interference between geo-stationary satellite earth stations and terrestrial microwavestations. The module SPECTRAemc provides propagation models for the complete radiofrequency range from LF to EHF and also allows for basic planning tasks. Optionally morespecialized tools for detailed analysis of certain services can be included e.g. HF or VHF/UHFanalysis tools for analogue as well as digital services. Furthermore specialized tools for land-mobile services, for satellite services and terrestrial microwave networks can be added to thesystem as soon as a need arises. In the following, the description of features is limited to basicEMC analysis functions of SPECTRAemc only.

In order to analyse or to plan a new station or network, for most radio services SPECTRAemc isthe appropriate generic tool to carry out technical analysis tasks.


57/109




Initially a selection of existing stations in the targeted frequency range has to be done from thecentral database. The result may be a selection of TX or links on the screen. It may bedisplayed on normal 2D maps or, if topographic data is available, also as a 3D view. Especiallyin terms of links, this type of visualisation gives extremely good information concerning thequality of planning, possible problems as well as proposals for solutions.

New transmitters can be generated; containing a basic set of information and be prepared for tasks like frequency assignment.

For that purpose, the device data may be visualized and edited in a comfortable environment.

1.2.3.3 Frequency pre-selection

Frequency pre-selection will usually be the first work to be performed in technical analysis.

By that means, it is detected, which frequency ranges are available for the requested serviceand as well, whether there are any free channels available, which will grant the highest

performance. The selection can be done in either of the tools SPECTRAplan or SPECTRAemc;both of them offer these possibilities.

After defining the frequency plan element, one would like to go with in terms of availablehardware or other boundary parameters, which may limit the choice of frequencies further, asearch in the database is carried out. As a result, the channel allocation for the desiredfrequency interval will be displayed, pointing out, which ones are occupied and which are theempty ones.

1.2.3.4 Propagation / Coverage Analysis

The result of a selection can be kept in a data table for further processing and analysis. Thecontents may be visualised on the map in order to get a geographical idea about possible

interference problems.

View of radio link network on a background land-use map

On the map, test receivers can be created and positioned. They should be placed at locations,where the new station or network shall have its major coverage area.


61/109




Exemplary set of tuneable and selectable propagation models

Using these receiver positions, a detailed field strength-analysis can be carried out, showing,which transmitters may really cause trouble. The prediction model can be selected according tothe current needs. Models, which are configurable, also allow modifying calculation parametersto optimise the result according to the local situation.

As a result, a report is generated, explaining the potential suffering from the existing network for the new station/network.

Dependent on the used model and source data material, such results may be presented in quitespectacular ways using the different available GIS data layers and combining them with result

data in overlay mode in 2D or 3D. As an example, a calculation for a cellular station in a urbanarea, based on 5m resolution data may be shown in the following:

1.2.3.5 Link Station Analysis

Microwave and other radio links may also be analysed by the tool. Also within the shortwavefrequency range one may analyse point to point connections where

appropriate.

For higher frequency ranges, path profile based results will be displayed, allowing to optimisethe location of receiver and transmitter station. Using a sliding cursor, one may instantly checkthe field strength and fade margin while modifying the link arrangement.

1.2.3.6 Interference Analysis

For a given scenario, e.g. after a final frequency assignment, but especially also during

negotiations, where new proposals may come up, a quick but powerful interference analysis isintegrated. It is the same mechanism also the frequency assignment is based upon and will takeinto account all stations of all services within the whole frequency range under investigation. Asa result, a report is created:
