a) Adjustable Automatically
The intelligent repeater with ALC function, microprocessor controlled gain attenuator, gain dynamic auto-adjust range reach more than 60dB, all these functions make sure the high reliability and high stability for our devices. (
Universal Mode repeater Only ALC function)
b) Oscillation Detective Indicate Function
After installation, our repeater have the function of oscillation automatically detection between the donor antenna and service antenna. The repeater will show indicated LED and lower down the gain automatically if the isolation is not enough until there is proper isolation. This function is make sure the security and no interference to the BTS network. (
Universal Mode repeater No such function)
c) Uplink/Downlink Auto Gain Synchronization
After the system is powered on, the input power is detected automatically and the output power is adjusted accordingly. After the downlink gain is calculated by the system, the uplink gain will be adjustment equivalently. This method can balance the system amplification. The both path gain is adjusted relevantly. So the repeater will not bring any interference and noise into the system link. One base station can hook up more than one repeater. (
Universal Mode repeater No such function)
d) Automatic Installation Indication—Easy Operation
Perfect indication for working statue will show the repeater correctly, it made installation and operation more convenient and easy.
