ST-GSM980 introduction:

 

You might have noticed that there are different gsm amplifier types. And it results troublesome to understand how to

 choose best gsm repeater for you. That’s why when you choose gsm repeater, we advise to take into account the

 following parameters:

 

· Working Frequency. The first step to do when you choose gsm repeater is to get to know what frequency your

 mobile operator uses. As a rule, European operators work within the 900 MHz GSM band for communication

 (GSM intelligence handset signal amplifier) and 3G for data transmission ( 3G amplifier). 

 

· Application of the GSM Repeater. Where are you going to use your gsm repeater? Inside your house, office 

or in a vehicle? For each application you need a specific type. By the way, a gsm repeater for vehicle use suits not 

only for cars, it can be installed inside trucks and boats as well; and every person inside the vehicle will get an

 improved signal.

 

· Dimensions of the Area to Cover. There are gsm repeater models created especially for small places

others – for middle-sized areas, and still others – for large locations. So you should approximately calculate what area you need to cover in square meters. 

After that you will have all the necessary parameters to choose a cell phone signal booster that suits your

 requirements best.

How to link the intelligence handset signal amplifier?

 

First, please kindly know what does the accessories in you complete set:

 

One outdoor antenna----you can choose log-periodic antenna or yagi antenna or fibre-glass epoxy antenna;

 

 

 

one amplifier----you can choose the single band host amplifier or dual band host amplifier or tri-band host amplifier;

 

indoor antenna----you can choose the ceiling antenna or panel antenna;

 

Cables----for 10m 75ohm coaxial cable for outdoor using, 5m for each ceiling antenna; 10m for each panel antenna;

 

splitters and connectorsSplitter, power splitters, couplers and N&F connectors.

 

Then installation such as these steps:

 A  Use of mobile phones at the top of building or around the building to check out the direction of the strongest 

signal location.

 

B  Select the appropriate location, and put the outdoor antenna fix to the wall or bracket.

 

C  Select the appropriate location of the indoor locations (this location could be best that close to power and a 

well-ventilated place, sun-proof, rain-proof) Install the Indoor Repeater, and fix on wall or bracket.

 

D  Put the outdoor antenna to the "OUT DOOR" connector and tightens it. Thus complete the outdoor antenna and

 Repeater's connection.

 

E  After setting the suitable location of the indoor antenna and the installation place, then fixing the antenna.

 

F The indoor antenna and Repeater wiring, the indoor antenna connect one end of the interface and on the other end 

connect Repeater's "IN DOOR" port.

Finally to Adjust the intelligence handset signal amplifier

 

A  Proper adjustment of the antenna's position so that the best communication quality and signal strength.

B  Indoor antenna installed location should stay away from one end of the outdoor antenna, so as not to interfere 

with each other. (The outdoor antenna away from the indoor antenna placed above a layer of floor is better)

C  Indoor antenna should be installed above the height of 2 m of the ceiling or the corner.

D  Using the waterproof tape to wrap where has connector, so as to avoid oxidation caused by moisture, resulting

 in reduced indoor signal coverage.
