GSM1900 Intelligent Repeater Repeater

1. Product Introduction
Pico repeater is applied specifically in small area indoor system. The base station signal is coupled and amplified by Pico repeater into in building system. The amplified signal is transmitted by indoor antenna. Meanwhile the indoor antenna will receive the cell phone signal, and send the signal to the base station as uplink. This method can eliminate the signal dead spot, reject the interference, and provide the stable signal communication for cell phone users. This Pico repeater mainly solves the problem spot problem in building.

Pico Repeater is a bi-directional amplifier that allows for the reception of signals, amplifies the signal and re-transmits into areas where there is no or very low signal level coverage enabling a mobile user to establish a call connection.


1) Characteristics

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.
