Implementation of the CDMA concept which uses codes for spread spectrum allows users to share bandwidth resources, so as to transmit signal in the same time and to be able to know the transmitter who sent the data signal. In this concept, the transmitted signal is distinguished at the receiver by means of orthogonal phase modulated codes which have low correlation among different users. This paper describes how wireless communication with the code division switching method is suitable for multi user connection. From a switching point of view, the code division concept realizes (1) supporting point to point, multi point and broadcast transmission, (2) user side routing, and (3) dynamic routing. From numerical results, this method has a better performance of transmission throughput than space switching
