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. -

Indoor antenna installation Correct antennas types shall be used according to the site conditions and the requirement. 1. Omni antenna (ceiling Omni or whip antenna) shall be installed in the center and radiate all directions. 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). -

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.

Accessories selection Choosing accessories pay attention to the two characteristics – frequency and impedance. All accessories shall support the repeater’s frequencies. -
Page 15: Questions & Solutions
Questions & Solutions What signal level in dBm is optimal for the correct booster functioning? For the optimal functioning of the booster, the BS (input) readings should be between - 65 and 50 dBm. The MS (output power) readings must be between +05 and +15 dBm. Device Gain must be 65/65 dB. If the BS is lower than - 65dBm, the coverage will be smaller. - Page 16 For maximum precision in signal level testing, switch your cell phone into Field Test Mode and see dB parameter. The closer dB signal level to 0, the better cell phone reception you’ll get. • -105 to -100 = Bad/drop call •...

Page 17: 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 18: 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. -
