METHOD AND APPARATUS FOR PROVIDING WIRELESS COMMUNICATIONS BETWEEN REMOTE LOCATIONS Abstract A wireless telecommunication system includes a microwave link between a main base station (100) and a remote reception and radiation site (106) capable of communicating with a plurality of telephone subscriber stations (107,108). At the main base station (100), radio frequency signals intended for the telephone subscriber stations are modulated (204) on a microwave frequency carrier signal prior their transmission, via a microwave antenna (112), to the remote site. At the remote site (106), the frequencies of the microwave signals, received at a microwave antenna (114), are reduced prior to modulating such frequency-reduced signals on a radio frequency carrier signal (302) and radiating, via a radio frequency antenna (115), the modulated radio signals out of the site. All radio signals received at the remote site from telephone subscriber stations are modulated on a microwave carrier signal (303) prior to their transmission, via a microwave antenna (114), to the main base station (100). At the main base station (100), the frequencies of the incoming microwave signals are reduced (208) prior to modulating such frequency-reduced signals on a radio frequency carrier signal (210) and coupling the modulated radio signals to a receiver.
