More Information
Summary:A distributed antenna system (100) includes a digital base station interface (202) and a plurality of remote antenna units (108, 110, 402, 404) remotely located from and communicatively coupled to the digital base station interface. The digital base station interface (202) is configured to receive at least one digital signal representative of at least one set of bands of analog radio frequency spectrum from at least one service provider interface (102) of at least one base station. The digital base station interface communicates at least one signal representative of these one set of bands of analog radio frequency spectrum toward the plurality of remote antenna units (108, 110, 402, 404). Each of the remote antenna units (108, 110, 402, 404) is configured to receive the at least one signal representative of the at least once a the band of analog radiofrequency spectrum or at least one signal derived from the at least one signal representative of the at least one set of bands of analog radiofrequency spectrum from the digital base station interface (202). Each remote antenna unit transmits the at least one set of bands of analog radiofrequency signals wirelessly using at least one antenna (626, 720).
