The IS-95 CDMA and CDMA radio channels use coded channels that are uniquely assigned to each user . This allows many users to operate on the same frequency. This also allows frequencies to be reused in every cell site and sectors within a cell site.

The CDMA channel is nominally 1.23 MHz wide . CDMA networks use a scheme called soft handoff, which minimizes signal breakup as a handset passes from one cell to another. The combination of digital and spread spectrum modes supports several times as many signals per unit of bandwidth as analog modes.
