1. Introduction
1.1. GENERAL DESCRIPTION
The goal of the Repeater system is to improve coverage for T-MOBILE AWS
(1710-1755MHz, 2110-2155 MHz) in medium size indoor areas of up to
50,000 sq. ft.
Figure 1-1: BDA-AWS21-26-4UT-AB-JXX Repeater
The system implements BDA technology to enhance coverage in urban
areas. Repeaters are used to fill out uncovered areas in cellular mobile
systems, such as base station fringe areas, road tunnels, business and
industrial buildings, etc. A Repeater receives signals from a base station,
amplifies the signals and retransmits them to service area. It also receives,
amplifies and retransmits signals in the opposite direction. Both directions
are served simultaneously.
In order to receive and transmit signals in both directions, the Repeater is
connected to a donor antenna directed towards the base station and to a
service antenna directed towards the area to be covered.
Control of the Repeaters is performed using a desktop or laptop computer
equipped with standard browser (no special software) which can
communicate with the Repeaters, either locally or remotely via modem
(optional).

3.2 OPERATING ENVIRONMENT
Cellvine's indoor Repeaters are intended for installation indoors only.
Do not install them where they might be exposed to direct sunlight and
rain\snow conditions as this could be harmful to the unit. For normal
operation, the environmental conditions should be as follows:
Ambient temperature range: –20 °C to +60 °C, Maximum Humidity: 90 %.
3.3 PRE-INSTALLATION INSPECTION
Before beginning the Repeater installation determine the following:
o Base station location and receiving power ( Tx power in dBm )
o Location where the DONOR/ Service antenna is to be installed
o Location where the Repeater is to be installed
o Length of coaxial cable needed to connect from the Donor antenna
to the Repeater unit
o Length of coaxial cable needed to connect from the Repeater unit
to the indoor antenna/s.
o Isolation estimation between the donor and the coverage antenna/s.
3.4 ANTENNAS INSTALLATION
3.4.1 Coverage (Service) Antennas
Coverage (service) antennas are facing to the service area. The mostly used
Antennas for indoor applications are Omni or panel antennas. When
multiple indoor areas need coverage, more than one antenna can be used.
The indoor antennas are usually placed near the ceiling with decorative
covers, antenna location decisions take into account isolation issues and
overcoming interfering signals. For outdoor coverage, panel antennas are
commonly used, location of the antenna is defined by coverage and isolation
matter.

Page 20
CELLVINE LTD. BDA-AWS21-26-4UT-AB-JXX
3.4.2 DONOR Antenna
DONOR antenna is installed outside, facing to the donor BTS. The donor
cell site should be chosen by considering capacity, range and signal level in
the outdoor antenna location. The location should be chosen so that the
donor cell site will be received at a higher level than all other adjacent cell
sites. If possible this antenna should be faced directly to the nearest cellular
site with a line of sight view. This antenna should also be properly
grounded with an appropriate grounding strap and lightning protection if
needed. Install the antenna according to antenna manufacturer
instructions.

3.8 TUNING DONOR ANTENNA
Locate a potential site for installing the Donor Antenna with an accessible
and comfortable working space. If possible locate a place with a line of sight
to the Donor BTS.
Deploy a coax cable between the Donor antenna and the Repeater location
and connect to the DONOR connector.
In order to achieve the best signal reception quality at the donor antenna,
rotate the antenna gently sideways and measure signal strength by an
approved test set.
3.9 ANTENNA ISOLATION
To assure proper Repeater operation, the isolation between the indoor
(Service) and Donor antennas should be higher than the Repeater's
maximal gain (15dB difference is recommended). This parameter can be
measured by injecting a pilot signal at the indoor antenna's (DAS) connector
and measuring the received signal at the DONOR antenna connector. The
isolation measured should be at least 15dB higher then the MAX GAIN of
the repeater. It is recommended to perform the test using a sweep signal
generator to cover the whole band. It is also recommended, to perform the
test in the opposite direction. (Injecting to the donor antenna and
measuring at the Service antenna's connector).
