Bidirectional Tower Mounted Amplifiers (BTMA) is equipment that
amplifies the primary base station uplink and downlink signals at
the same time. Its main functions are as follows:
1. Enhance the level strength of uplink and downlink, boost up
deepness and extent coverage ranges.
2. By amplify the uplink signal to debase noise of base station
receiving system, enhance sensitivity.
3. Debase dropping rate and handoff rate, enhance talking quality.
4. Increase traffic, enhance economy benefits.
5. Debase mobile phone output power, purge electromagnetic
