Signal coverage area :
| 1.Support Maximum coverage area is 2000 square meters.
( Depend on the area condition)
2.One indoor antenna only use for about 300 square meters.
If want to make all use of 2000 square meters which the host supports,
need to add more indoor antennas (about6-7) and power divider / splitter.

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.
1) Fix up outdoor antenna reception on housetop
or outside the window and point it to the signal tower.
2) Connect outdoor antenna to “BTS” port in repeater machine through cable.
3) Connect indoor antenna(s) to “MOBILE’ port in repeater machine through cable also.
4) Plug power adaptor into AC power socket and finish installation.
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 -50DBM.
2) If can not call out, please adjust the direction of outdoor antenna.
3) If strength is not steady, please check if outdoor & indoor antennas are too close.
Please ensure the outdoor and indoor antennas have distance of 10 meters at least,
with a wall between and not in a same horizontal line.
To use this product to enlarge your signal, the outdoor signal shall be as good as possible.
The product will not work well if your outdoor signal is not good or bad.
