Abstract
A wireless communication system employing spread-spectrum communication techniques includes a plurality of base stations that may be coupled directly or indirectly to a telephone network, and may initiate or receive calls on the telephone network. A plurality of user stations may include a spread-spectrum transmitter and receiver and may provide for dynamic connection to selected base stations. In one embodiment, one or more of the base stations may include an augmented base station and include means for communicating with the user stations over an alternative communication path distinct from a spread-spectrum path, such as over a cellular communication path.
