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.
