General
The 850 / 2100MHz 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.

Product Description
With ALC AGC Function
Can control gain automatically. Avoid base station interference
Network support : CDMA 2/3G + WCDMA 3/4G
Gain : 70dB
Power Supply : AC110V～220V;DC+5V/2A
Connector Type : N-female connector
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.
Technique supporting:
1. If still no signal receipt after activated repeater,please check if outdoor antenna point to signal tower or elsewhere have strong signal and check if strength achieve -70dBm.
2. If cannot call out,please adjust the direction of outdoor antenna.
3. If the strength is not steady,please check if outdoor and indoor antennas are too close;please ensure the outdoor antenna and indoor antenna have distance of 20meters at least,with a wall between and not in a same horizontal line.
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.
FAQ:
