SPECIFICATION Indoor coverage: 13000 ft² Up-link freq: 890-915 MHz Down-link freq: 930-960 MHz Up-link Gain: 70 dB Down-link Gain: 80 dB Power supply: Input AC90~264V,output DC5V/2A Working t °C: -25/+55 Humidity: 5 - 95 % Size (mm): 193 × 116 × 27 Booster Weight: 1 kg dBm:... - Page 6 5. 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;...

6. ANTENNAS AND CABLES SETTING UP 6.1. 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. -

If the system shows “Device was damaged” note, it means that the uplink/downlink was damaged. Contact customer service for repair. 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. - Page 17 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 18 - Use some obstacles (Such as walls). 2. The repeater’s power is on but the phone cannot get connected to the network and still can not communicate. Reason 1: There are loose or wrong connections in the repeater system. Solution: Please try to fasten the connections between different parts of the system. Reason 2: The signals received by outdoor antenna of other operators nearby are too strong.
- Page 19 8. FAQ 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.
