ABSTRACT:
A microcell architecture includes a macrocell base station capable of receiving signals from and transmitting signals to at least one microcell base station provided within a first predefined geographic area. The macrocell base station includes circuitry for converting downstream channel unit information to downstream baseband channel information and for modulating and transmitting the downstream baseband channel information. It also includes circuitry for demodulating received upstream baseband channel information and for converting the received baseband channel information to upstream channel unit information. Also provided is at least one microcell base station, provided within the first predefined geographic area, for communicating with wireless terminals within a second smaller predefined geographic area within the first predefined geographic area. The at least one microcell base station receives and demodulates the downstream baseband channel information and modulates it to an intermediate frequency signal for transmission to a wireless terminal. The at least one microcell base station also receives and converts upstream information from a wireless terminal to an intermediate frequency signal, separates the upstream information into baseband channel information and modulates and transmits it as the upstream baseband channel information to the macrocell basestation.
