Abstract: A fixed wireless communication system (100) is a hybrid of a fixed wire-line telephone system and a conventional cellular radio system. In particular, this fixed wireless telephone system (100) provides an instant communication link between a user's fixed wireless terminal (101) and a wire line communication system (105), allowing a user to dial another user's number, as well as, receive call progress tones such as the dial tone. This link is established by detecting (403) an off hook signal at the communication device, transmitting (405) a call set up request with a “ghost” telephone number over the conventional cellular system, and recognizing (411) the “ghost” telephone number, requesting (413), responsive thereto, an audio link on the wire line communication system (105), and linking (415) the audio link on the wire line communication system with the first communication device over the conventional cellular radio communication system.

Abstract: A method and apparatus for immediately identifying the presence and the source of interference in a communications system. A separate identification code is superimposed on each signal transmitted from a separate transmitter. At any receiver, if an undesired signal causes interference, it can be idenified via its associated identification code. In one embodiment, spread spectrum chip sequences are used as the identification codes.
