Characteristics
adaptive upli nk switchi ng off
The repeater detects the cell phone sig nal automatically .In case there is no uplink power received, and the uplink path is shut off by the repeater. This function can prevent the system from the case the uplink power is detected,
the repeater upli nk path is ope ned automatically. So the com muni cati on is established.
digital ALC/ analog ALC
With the function of digital ALC and analog ALC, the dynamic gain adjustment range is 60dB. The system ALCis double redundancy , It provide the high reliability and stability.
Oscillation automatically detected function
It has the function of oscillati on automatically detecti on betwee n the donor antenna and service antenna.
Uplink/downlink gain adjustment synchronization Uplink and dow nli nk gain setup automatically
After the system is power up, the in put power is detected automaticallyand the n
the output power is adjusted. After the dow nli nk gain is calculated by the system, the upli nk gain can be adjustme nt equivale ntly. This method can bala nee the system amplification. The both path gain is adjusted relevantly. The system gain is less than the system path loss. So the repeater will not bring any interfereneeand noise
into the system link. One base station can hook up more than one repeaters.
The function ensures that Pico Repea
