Abstract

A system for accessing a telephone system (101) in which a set of user stations (102) are matched with a set of base stations (104) for connection to a telephone network (103). Each user station comprises a spread-spectrum transmitter (109) or receiver (108) and is capable of dynamic connection to selected base stations (104).
User stations may use CDMA, FDMA, TDMA or other multiple-access techniques to obtain one or more clear communication paths to base stations. Base stations are coupled to each other by means of a private exchange telephone system or other small business telephone system (such as a PBX, Centrex, or key-type system) so as to couple user stations in calls outside the telephone network. User stations may also be coupled directly or indirectly to the telephone network on their own or by another access path, such as narrowband or spread-spectrum cellular telephone circuits.
