can display signal strongness which it receives from outdoor antenna ,
the signal bar will be full black if the signal is received very good.

Signal coverage area :

1.Support Maximum coverage area is 2000 square meters.( Depend on the area condition)
2.One Ceiling antenna only use for about 50-150 square meters. (in open space).
   If want to make all use of 2000 square meters which the host supports,
   need to add more indoor antennas (about8-10) 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.

Installation Approaches:

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.

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 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 20 meters at least,

  with a wall between and not in a same horizontal line.

 

Note :
1.To use this product to enlarge your signal,
the outdoor signal where put outdoor antenna shall be as good as possible ,
the signal in your mobile phone shall be full and must be very stable for talking .
The product will not work good if your outdoor signal is not good or bad .


2.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.

3.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,
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.

4.We will not bear any responsibility of your outdoor signal is not good .
And if your outdoor signal is not full,
for example, the full signal shown in your phone is 5 bars,
and you can only have it 4 bars ,then please think it over again before buy.
