Abstract
A wireless communication system employing spread-spectrum communication techniques. A plurality of base stations 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 comprise a spread-spectrum transmitter and receiver and may provide for dynamic connection to selected base stations. In one preferred form, one or more of the base stations may comprise an augmented base station and include means for communication with the user stations over an alternative communication path distinct from a spread-spectrum path, for example, over a cellular communication path. The augmented base stations may also communication with one or more cluster controllers, enhances service processors, or control stations coupled to the telephone network.
