<p>A spread spectrum code division multiple access (CDMA) transmitter for communicating data to a spread spectrum CDMA receiver in a same geographic region as covered by a cellular system, the cellular system communicating using a plurality of predetermined frequency bandwidths, is disclosed. The CDMA transmitter is characterized by means (151, 153, 253, 257, 171, 173, 273) for generating a spread spectrum CDMA data signal spread with a pseudo random chip code sequence, the CDMA data signal having a wide bandwidth overlaying said plurality of predetermined frequency bandwidths and means (155, 157, 159, 255, 175, 179) for transmitting said spread data signal to said CDMA receiver. A method of transmitting data between a CDMA transmitter and a receiver with a bandwidth which overlays frequency bandwidths of a cellular system is also disclosed. <IMAGE></p> |
