Cell Phone Signal Amplifier 850MHz
Cell Phone Signal Amplifier Function:
Cell Phone Signal 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.
Features:
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 Signal 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
