SECTION 1

1.0 Introduction

1.1 Intended purpose

Mobile phone systems are planned as cellular systems. Each cell of the basestation has to cover a certain geographical area with the signal within definedpower levels. Due to the physics of radio propagation, even using high radiatedpowers or complicated antenna systems, there are zones within the coveragearea, where the signal coverage cannot be achieved by the base station.

Repeaters traditionally have been used to fill in dead Zones areas with nocoverage due to blockage by terrain, foliage, man-made structures or distancefrom the base station. The user views repeaters as a means to extend basestation coverage, so as to reduce the number of required base stations and,thereby, accelerate network coverage availability.

1.2 About FCRG-6

Repeater type FCRG-6 is a Channel Selectiveamplifier, which bi-directionallyamplifies signals between mobile stations and a base station in the GSM900/1800 mobile telephone system. It provides highly selective amplification ofchannel, (one operator) thus enabling radio coverage in regions where

satisfactory Cellular coverage is required.

The repeater can be controlled locally or remotely. The design of the repeatercomprises a large number of functions, which the operator may monitor viaSHYAM RMS application software. An easy to understand and learn windowsbased GUI supports the customer to query status reports from the repeater or tochange settings.

a. DONOR ANTENNA

Donor antenna is used to receive signal from the base station and switchelectromagnetic wave into RF signal and vice versa. The antenna with more than

10-14dB gain sends received signal to the repeater and transmits uplink signalsamplified by the repeater.


Figure 1.4-3 : Donor Antenna

b. DUPLEXER (DOWN-LINK)

The main function of duplexer is to isolate the uplink frequency from the downlinkfrequency, i.e. isolate transmit path from receive path. The bandwidth of theduplex filter depends upon the operators frequency band (25MHz, 15MHz,10MHz, 9MHz, etc.).

1.4.2 Gain sett ing

It is the Repeater gain that will dictate how far your repeater can extend thecoverage and whether or not the noise contribution will have a measurable effectat the base station. The most important task involved in a repeater installation is

to set the repeater gain properly.

Introducing attenuation into the amplifier chain will adjust the repeater gain. Byusing GUI based local RS 232 serial interface, the gain can be adjusted locallyfrom 0dB to 31 dB maximum in steps of 1 dB. Moreover, two more methods arealso used to set the gain of repeater i.e. by using keypad & display (Optional) orGUI based remote GSM modem (Optional). The gain setting for Uplink andDownlink path is independent of each other.

For example, if repeater has a maximum gain of 90 dB and the required repeatergain is of 60 dB, then the attenuation is to be set at 30 dB,

Note:- Repeater gain should be at least 15 dB less than the antennaisolation.

1.4.2.1 Forward Gain Setting (Downlink Path)

Signal transmitted by BTS is called Downlink/Forward signal and the signaltransmitted by mobile phone is called Uplink/Reverse signal.

Setting the forward gain is very simple method. Forward signal level can be

measured using NET engineering software in any NOKIA handset e.g. NOKIA6210 or any other engineering mobile handset. Please refer How to use NETEngineering Software manual to use NET engineering software.

Alternatively, RF output power of repeater can be measured using the GUI basedlocal RS 232 serial interface or visual indication shown on the display panel of therepeater (optional) or GUI based remote GSM modem (Optional).

CH1 CH2

Figure 1.4.2.1-1 : Display panel

Once the RF output power has been determined, the attenuation will have to be

modified to reach the desired output signal level.

Let us take an example of a suburb area,which is 15-20km away from the basestation site and the mobile signal level is almost negligible on the road to set up amobile call. At the outset, identify the physical location in an area where thereceived mobile signal level is optimum and follow the steps as enumeratedbelow.

Step: 1 Measure the mobile signal level, using NOKIA 6210 handset and theSIM card of the cellular operator, on the road where the mobile signallevel is optimum and mark this location as point A.

the same time we should also consider the antenna isolation parameter,which primarily depends on the vertical distance between the donor andserver antenna. (Please refer to antenna isolation data sheet andrepeater gain vis-a-vis vertical separation between donor antenna andserver antenna for setting the repeater gain.) Please ensure the

repeater gain should be at least 10db lower than the antenna isolation.

The gain of repeater can be set using any of the following methods:

a. Local manual mode (using built in key pad and display)b. Local RS 232 serial interface mode (GUI based)c. Remote via GSM modem, optional

Please refer to section 3 for further information.

Step: 4 Now, let us again measure the mobile signal level at the same locationswhere we had measured the signal level before the repeater installation

Please note that the received signal may vary from 75 dbm to some other valueas it is highly dependant on the physical location of the area to be covered.

1.4.2.2 Reverse Gain Setting

In Repeater coverage area, the mobile phones will have strong signals thereforethe reverse path gain must be optimized. The gain should be low enough so asnot to cause an enormous increase in interferences at the base station, but highenough to ensure a strong signal.

1.4.3 ALC

In order to protect the amplifiers from overload and to prevent the systems togenerate spurious emission, the repeater has anAutomatic Level Control (ALC),designed to limit the output power to a defined level. In order to avoid oscillation,the control amplifier has an integrating characteristic, so that a step function

response obtains a delayed rise and decay.

1.4.4 Contro ller module (Supervisory)

The controller module is a microcontroller. The man-machine communicationbetween the cellular operator and the repeater can be done via the controlmodule by using any one of the following methods:

Local Display & Key pad.

RS 232 interface

GSM modem (Optional)

By using the GSM modem, the repeater can be controlled and monitoredremotely.

Frequency and gain of channels, output power and status messages can bereceived remotely. In case the GSM modem is connected, automatic alarmmessages can be received at remote locations.

2.0 Installation

Figure 2.0-1 : Repeater system descript ion

The repeater system FCRG-6 consists of two units. One is called Master Unit andis located close to the BTS. Other unit called Remote Unit is located close to the

area to be covered. Master unit is used to convert required GSM channels to anew frequency in the allocated RF band of the operator. The converted channelsare used as a radio link connection to the Remote Unit. The Remote Unitreconverts the GSM channels and transmits to the coverage area.

2.1 Pre-installation Considerations

Once the expected coverage area is determined and a site installation plan isestablished (as per the site survey format), a pre-installation checklist shouldbe considered and reviewed for the following items:

1. Identify the service providers base station location and measure theavailable signal strength at the exterior of the installation location.

2. Identify the installation location for the donor antenna, and review theantenna manufacturers installation procedures for additionalconsiderations. Ensure that the donor antenna has a direct line-of-site tothe service providers base station. If the line-of-site is obstructed,determine the azimuth position by using a magnetic compass forapproximate alignment of donor antenna with base station antenna.

3.1 Preparation

Note:- Repeater should not be connected to Power withouttermination of the antenna connection. The termination can beperformed either by the antenna connection as well as a dummy load

or the 50 terminated connection of a measuring instrument (PowerMeter, Spectrum analyzer with appropriate PAD)

Before bringing the repeater system into service it is necessary to measure theantenna isolation. The repeater system has its maximum available gain when theattenuation is set to zero. On site the maximum allowed gain is 10 dB less thanthe value of antenna isolation. In order to check the function of the repeater

system on site it is advisable to operate the repeater system with 50 terminations. This makes it possible to set the necessary gain and to test the setvalue without the necessity of radiating.
