Abstract: A wireless telecommunications system architecture is disclosed that is capable of supporting a centralized block radio architecture and of distributing the information-bearing signals from the block radio to geographically-dispersed radio heads using relatively low-cost cable (e.g., twisted-pair, etc.). In accordance with the illustrative embodiment of the present invention, a radio multiplexes, modulates, and channel codes one or more information-bearing signals and upconverts them, not to radio frequency, but to an intermediate frequency that can be transmitted over a low-cost cable. Co-located with each radio head is an upconverter that upconverts the intermediate frequency signal to radio frequency in preparation for radiation by an antenna.

Abstract: A wireless telecommunications system architecture (400) is disclosed that is capable of supporting a centralized block radio architecture (403) and of distributing the information-bearing signals from the block radio to geographically-dispersed radio heads (401-1 ... 401-6) using relatively low-cost cable (402-1 ... 402-3) (e.g., twisted-pair, etc). In accordance with the illustrative embodiment of the present invention, a radio multiplexes, modulates, and channel codes one or more information-bearing signals and upconverts them, not to radio frequency, but to an intermediate frequency that can be transmitted over a low-cost cable. Co-located with each radio head is an upconverter that upconverts the intermediate frequency signal to radio frequency in preparation for radiation by an antenna.
