Pico repeater is applied specifically in small area indoor DAS system. The base station signal is coupled and amplified by Pico repeater into in building system. The amplified signals is transmitted by indoor antenna. Meanwhile the indoor antenna receives 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, provide the stable signal communication for cell phone users. This Pico repeater mainly solves the problem spot problem in building. The coverage area is as large as 3000 square meters in open space, and 1000 square meters in partial obstacle area, 500 square meters in complete obstacle area. The edge power level for coverage area is above 85dBm. The repeater output power level is less than 20dBm.  

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.

Pico Repeater can be deployed in indoor coverage and dead area. It is especially advantageous to use in 100-1000,which is a very economical solution.
