2G 3G 4G Dual Band Signal Booster CDMA DCS Cell Phone Repeater Amplifier
General
 The 850/1800MHz Pico Repeater provides an affordable solution to solve the indoor signal coverage problems due to signal fading and attenuation caused by architecture obstacles. And its easy installation and maintenance can help carrier get fast return.
 The repeater is working as a relay between the BTS and mobiles. It picks up the strongest signal from BTS via the Donor Antenna, linearly amplifies the signal and then retransmits it via the Indoor Signal Distribution System to the weak/blind coverage area. And the mobile signal is also amplified and retransmitted to the BTS via the opposite direction.

Accessories
a. One dual band signal booster;
b. One indoor antenna;
c. One outdoor antenna;
d. 20meter cable and 5meter cable;
e. User manual;
f. Power adapter.

Installation Approaches
1. Fix up outdoor antenna reception on housetop and point to signal tower;
2. Connect outdoor antenna to “outdoor” port in repeater nachine through cable;
3. Connect indoor antenna(s) to “indoor” port in repeater machinethrough cable also;
4. Plug power adaptor into AC power socket and finish installation.



The repeater makes the signal stronger in places with poor signal coverage such as:
1) Underground areas: basements, parking lots, tunnels;
2) Other places where cellular signal is shielded by metal or concrete walls: offices, supermarkets, cinemas, hotels;
3) Places distant from the BTS like private houses.
