Short for code-division multiple access; a technology used in wireless communications for second-generation and third-generation wireless networks. It allows many signals to occupy a single transmission channel in order to optimize the available bandwidth, a process called multiplexing. CDMA is used in UHF (ultra-high- frequency) cellular telephone systems in the 800-MHz and 1.9-GHz bands. Wireless companies that use the CDMA technology include Sprint, PCS and its affiliates, Verizon Wireless, and Qwest Communi-cations International Inc.
