Code Division Multiple Access definition

Code Division Multiple Access or "CDMA" means a method of digital spread spectrum technology wireless transmission that allows a large number of users to share access to a single radio channel by assigning unique code sequences to each user thus permitting multiple simultaneous radio transmissions on the same radio channel or frequencies.
Code Division Multiple Access. (`CDMA')" shall mean CDMA-based telecommunication services provided by the System, operational in the 1900 MHz band.
