How CDMA Works. CDMA uses a “spread-spectrum” technique whereby electromagnetic energy is spread to allow for a signal with a wider bandwidth . This approach allows several people on different cell phones to be “multiplexed” over the same channel to share a bandwidth of frequencies.

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.
