CDMA

The dominate PCS standard in the United States, this spread-spectrum technology, developed by Qualcomm, lets multiple callers share a segment of frequencies.

Code Division Multiple Access and Time Division Multiple Access dual-mode cellular telephones that aid in the receiving of fax and computer network data on computers and PDAs. (See also Wireless Glossary of Terms , CDPD , Networks and PDA )

Short for Code-Division Multiple Access, a digital cellular technology that uses spread-spectrum techniques. Unlike competing systems, such as GSM, that use time-division multiplexing (TDM), CDMA does not assign a specific frequency to each user. Instead, every channel uses the full available spectrum. Individual conversations are encoded with a pseudo-random digital sequence.CDMA was developed by Qualcomm, Inc.
