Abstract

A wireless OCDMA communication system in which there is a cluster of base stations (BS), or radio fixed parts (RFP), which may in turn be controlled by a wireless cluster controller (WCC). The system uses frames of a time division duplex spread spectrum signal for two-way voice and/or data transmission, and a plurality of handsets, portable parts (PPs), or more complex subscribers, each adapted to communicate with the BS, or RFP, using the communication system, can be used to implement a variety of system configurations and provide a variety of at least two levels of service selected from a wide variety of services.

Claims

1. A wireless OCDMA communication system in which there is a cluster of base stations (BS), and radio fixed parts (RFP), which are selectively controlled by a wireless cluster controller (WCC), said OCDMA communication system including frames of a time division duplex spread spectrum signal for two-way voice and/or data transmission, and a plurality of handsets, portable parts (PPs), and complex subscribers, each adapted to communicate selectively with said BS, or RFP, using said OCDMA communication system, and means to implement a variety of system configurations and provide a variety of levels of services, comprising:

a) a single base station and radio fixed part, and single portable part system for providing conventional telephone service,

b) a single base station and radio fixed part, and multiple portable parts for providing communications with a public switched network telephone,

c) a single base station and radio fixed part, and multiple portable parts for providing key system service with a proprietary interface or with an ISDN interface,

d) multiple base stations and radio fixed parts, and multiple portable parts for providing key system service with the capability of roaming and handover over an extended multiple cell service area,

e) multiple base stations and multiple radio fixed parts, and multiple portable parts interfacing to one or more PBXs for providing wide area network (WAN) coverage system capability, for a private network, and a Telepoint system capability for a public network,

f) multiple base stations and multiple radio fixed parts, and multiple portable parts for providing a wireless local loop capability,

g) multiple base stations and multiple radio fixed parts, and multiple portable parts together and subscriber terminals interfacing to the PSTN via satellite links for providing a wireless OCDMA telephone system capability, and

h) multiple base stations and multiple radio fixed parts, and multiple portable parts and subscriber terminals together with a wireless cable distribution system for providing wireless voice and data distribution system initially distributed via cable.
