How Booster/Repeater Works?
Repeaters are designed to fulfill the idea of one and main principle: to fill the areas with
the weak or bad signal and to amplify these low signals in order to provide you with the
communication suitable for you.
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 Approaches
- Fix up outdoor antenna reception on housetop and point to signal tower.
- Connect outdoor antenna to “BTS” port in repeater machine through cable.
- Connect indoor antenna(s) to “MS” port in repeater machine through cable also.
- Plug power adaptor into AC power socket and finish 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.
3.If the strength is not steady, please check if outdoor and indoor antenna are too close, pls ensure the outdoor antenna have distance of 10 meters at least, with a between and not in a same horizontal line.
4.keep antenna and booster far from windows.
5.pls put indoor antenna in place which is above 2 meter high and far from wall to installation.
6.Packed the connector by waterproof glue, otherwise wet reduce the signal cover area.
Note :
Please check your outdoor signal condition before placing the bid.
if sometimes the signal is full,sometimes no signal again in your mobile, or you couldn’t call out when the signal is full, it couldn’t be used any booster in your environment.
Cell phone signal amplifier is impossible to ensure all environments are 100% effective, because the SIGNAL is very complex, especially in the city, no one can guarantee 100% available ,in some areas the signal is not necessarily the GSM900, some of the signal is reflected signals, even the signal display very well,but the quality is poor, and have encountered a lot of environment can not be solved with any booster.
The product will not work good if your outdoor signal is not good or bad .
We will not bear any responsibility of your outdoor signal is not good .
