Page 6: Repeater System Overview
REPEATER SYSTEM OVERVIEW The picture below shows how simple and fast booster installation is and how effectively it works. A Yaggi or panel antenna (it depends on the booster model and its power), as donor/outdoor antenna, is installed at the top of the roof to pick up good mobile signals from the base station, and sends them through the cable to the booster where the signals get amplified significantly;... -
Page 8: Antennas And Cables Setting Up
ANTENNAS AND CABLES SETTING UP Outdoor antenna installation The repeater’s main function is to improve weak RF signals in an area. The formula is: Input power + Gain= Output power. The signal strength from an outdoor antenna directly affects the efficiency of the indoor coverage. It is very important to choose the correct outdoor antenna location in order to get the best signal. -

ground wire isn’t looped or coiled. The suitable grounding locations can as follows: a ground rod (a metal rod normally buried outside the house), an electrical service panel (it is connected to the ground rod of the house), metal structure of a building (provided that this structure is grounded itself). - Page 11 2. It is better to use a directional panel antenna or Yaggi antenna when the area shape is long and narrow (corridors, long row of houses in two sides, tunnels or elevators or rural open space). Requirements to indoor antenna installation: •...

Page 12: Repeater Installation
REPEATER INSTALLATION Installation requirements Installation Location Requirements 1. The repeater shall be installed indoor in a cool, dry and ventilated room without erosive gas or smoke, or on a cool and ventilated wall to ensure excellent heat dissipation. 2. Installation height should be sufficient for RF cable wiring, heat dissipation and maintenance. 3. - Page 13 INSTALLATION STEPS 1. Find an appropriate position for an outdoor antenna. ( see the r equirements in 6.1. sect. ) 2. Plug in the outdoor antenna to the mobile booster from BS side and fasten tightly. 3. Plug in the indoor antenna to the mobile booster from MS side and fasten tightly. 4.

Status ALARM It is working in linearity Green Warning: Input signals may be not enough, so please check on coverage effect, do not do anything if it is good coverage; otherwise please adjust the repeater system to get better coverage. A little bit stronger input signals or slight self oscillation have occurred. -

Repeater Commissioning Downlink gain setting First the alarm LED only indicates the downlink input power level, here we use color of Alarm LED to adjust the gain of the repeater. Alarm LED color must remain green. As for the downlink working performance, it is a good working point that Alarm LED maintains “Green”... -
Page 19: System Test
System Test Check whether the coverage is good 1. Take a test with a mobile phone or a data card (engineering mobile phone is preferred). If the signals in most areas have not been improved, please check recommendations below again: - Weak input signal leads to low output power. -
Page 20: Repeater Can Not Communicate In Power-On Status
Remark: • Reduce attenuation values * — by ensuring the isolation level • Increase output power * — recommended ways: to adjust outdoor antenna direction/location, or replace it to an antenna with higher gain to increase input signal strength. Repeater can not communicate in Power-ON status 1. -
Page 21: Will Booster Increase The Rf Radiation
1. Will booster increase the RF radiation? No, it will decrease instead. Every cell phone irradiates heavily being in zones with poor mobile signal as a cell phone is constantly in searching mode. The danger is your cell phone is about 2cm to your body, which makes its usage rather harmful. And when a booster is installed, it improves the mobile signals in the coverage, and your cell phone stops irradiating strongly, thus it will reduce the RF radiation of the mobile phone tremendously. -
