Anti-oscillation mechanism: There is the module to detect the oscillation signal when power on. If there is the oscillation
detected, the device will shut down the links (uplink within 300ms, downlink within 1s) ; 1 minute later repeater will restart and
detect the oscillation signal again, this process will repeat 5 time till the repeater is totally shut down. Please refer to the testing
report in the FCC.
AGC: If the input signal is detected to be too large, the MCU automatically control the transmission to reduce the gain of
output signal to ensure that the output signal power level compliance with the factory setting. If the output signal of the
amplifier is detected to be too large, the MCU automatically controls the input signal to ensure compliance with the
factory setting.
Noise-power limiting circuit: When there is no mobile phone signal in 5 minutes at the covering area, the device will shut
down the
uplink, so as to not to affect the BTS.
