Cell Phone Amplifier 850MHz

Cell Phone Amplifier 850MHz
Product Detailed
Cell Phone Amplifier: 1,Various types: 2W,5W,10,20Wetc. 2,Gain adjustable;Max.95dB; 3,High output power for outdoor;

Cell Phone Amplifier Function:

Cell Phone Amplifier is designed to solve problems of weak mobile signal,which is much cheaper than adding a new base station (BTS).

Main operation of the repeaters are to receive lower-power signal from BTS via RF transmission and then transmit the amplified signal to the areas where network coverage is inadequate.And the mobile signal is also amplified and transmitted to the BTS via the opposite directon.


1)Extend the coverage;

2) Lower investment cost;

3)Easy to operation;

4)Advanced technology to flexibility and proved reliability;

5)Modular design enables easy upgrade;

Typical Application:

Kingtone  Cell Phone Amplifier widely used in the areas with small traffic volume and vast coverage.They are used in the places below:

Railways            Tunnels             Scenery Spots          Compuses                  Hospitals

Oil Fields            Roads             Touns             Rual areas              Airports          Venues

Factories           Farms              Mountainous areas
