This allows several users to share a band of frequencies (see bandwidth ). CDMA is an example of multiple access, where several transmitters can send information simultaneously over a single communication channel. CDMA offers the benefits of multipath diversity and soft handoffs.Īs an air interface technology, WCDMA is able to artificially increase a signal's bandwidth. Code-division multiple access ( CDMA) is a channel access method used by various radio communication technologies. The TDD mode of WCDMA actually employs a combination of TDMA and CDMA.ĬDMA allows multiple users to share a channel at the same time, while TDMA allows users to share the same channel by chopping it into different time slots.
