When implemented in a cellular telephone system, CDMA technology offeres numerous benefits to the cellular operators and their subscribers. With CDMA, unique digital codes, rather than separate RF frequencies or channels, are used to differentiate subscribers.
All users share the same range of radio spectrum.
This is then spread to a transmitted rate of about 1.23 Megabits per second. Spreading means that digital codes are applied to the data bits associated with users in a cell. These data bits are transmitted along with the signals of all the other users in that cell. When the signal is received, the codes are removed from the desired signal, separating the users and returning the call to a rate of 9600 bps.
