Repeater GSM 900 20dBm

1． GSM Repeater 3.1 Wireless Repeater Product Introduction GSM wireless broadband repeater is a kind of GSM mobile communication signal bi-directional amplification equipment, which can be used to improve the quality of mobile communications services at signal blind areas caused by topographical characteristics or high-rise buildings, as well as where base station signal can not cover. Wireless Repeater picks up RF signals from the base station by using donor antenna, then transmits the RF signals to the area that needs to be covered through retransmission antenn after being amplified so as to expand donor base station signal coverage; The repeater can directly access received RF signals to indoor distributed system as indoor coverage source.
