Cell phone becomes especially helpful when people get into critical situations. In case of emergency a timely call can save somebody’s life.
Unfortunately, there are still some places where one can find themselves “out of coverage”. Usually those places are either too far from the cell phone base station or located inside underground constructionsA. High-gain linear power amplifier
B . ALC and AGC function technology ,
C. Ultra-low noise receive amplifier
D. There is no interference to the base station
E. Stable and reliable electromagnetic compatibility design .
F. The base station dose not cause an increase in background noise ,but will not
lead to a decline in the quality of the base station communications
G. With full-duplex communication mode .
