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.
Steps that describe the work of Repeater.
1) The outside antenna receives the signal from the nearest mobile base station.
2) The outside antenna sends the received signal through the coax cable to the installed Repeater.
3) The repeater accepts the low signal and improves it.
4) The improved signal goes to the inside antenna through the connection coax cable.
5) The inside antenna send the improved good signal to your mobile phone.
Installation
Technique Supporting
- 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.
- If can not call out, please adjust the direction of outdoor antenna.
- If strength is not steady, please check if outdoor & indoor antennas are too close. Please ensure the outdoor and indoor antenna have distance of 20 meters at least, with a wall between and not at the same horizontal line(outdoor antenna can be one floor higher than the repeater and indoor antenna).
- Indoor antenna and repeater better to be minimum 4 meters far away from nearby windows and doors.
Note:
To use this product to enlarge your signal, the outdoor signal shall be as good as possible. The product will not work well if our outdoor signal is not good or bad.
In case the indoor signal is always very low while outdoor signal is very good, the repeater can work well. If the indoor signal is sometimes full sometimes not at all before installing, this environment is not suitable to install the repeater.
