Abstract
The invention relates to a duplex outdoor base station utilizing a hybrid system of a high amplifier and optic antenna to communicate over both radio and optic frequencies. The base station includes: a RF front end part interfaced with an optic antenna; a receiver interface unit for transmitting the received signal to the RF front end part after amplifying a received signal; a transceiver unit for transmitting the transmitted/received signal to the RF front end part; a base station transceiver subsystem (BTS) test unit, coupled to the front end part, for performing a self-diagnosis of a BTS; and an optic antenna interface unit for connecting an optic antenna system with the receiver interface unit. This base station transceiver subsystem (BTS) is a kind of hybrid system for simultaneously operating an optic antenna and a radio frequency antenna.
