900MHz 1800MHz 2100MHz Multi Band Repeater
Cellular Booster 900/1800/2100MHz Multi Band Repeater 2G 3G 4G Mobile Signal Amplifier
Selling Point
1. Smart LCD: Show the real-time signal strength.
2. Sleeping Mode: When no user calls, the device works in Sleeping mode, so as to achieve the purpose of energy saving.
3. ALC(Automatic Level Control): Automatically adjust the output gain down to optimal figure while the output gain is above the optimal figure by the ALC circuit, this can greatly optimize the calling and data transfer quality.
4. AGC (Automatic Gain Control) : When the downlink output signal is too strong or self-oscillated, booster can automatically reduce the gain and reduce the interference signal.
5. MGC (Manual Gain Control): In order to install the booster conveniently, all frequency band of the booster have the Gain attenuation adjustment function, the adjustment scope is 0-27dB.

Product Description
Model No : AS-900/1800/2100/H
Network support : GSM 2G + DCS 2/4G +WCDMA 3/4G
Gain : 80dB
Connector Type : N-female connector
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.
