    - TDMA is abbreviated as “Time-Division Multiple Access” and CDMA is abbreviated as “Code-Division Multiple Access”.

    - In TDMA only a single user is actually utilizing the channel at any given instance, while in CDMA, it is a kind of multiplexing that allows several signals to use a single transmission channel.

    - TDMA is the most cost effective technology to convert an analog system to digital.

    - CDMA has a very high spectral capacity compared to TDMA.

    - CDMA uses a vocoder EVRC for noise reduction where the background noise is reduced and can accommodate more users per MHz of bandwidth.

    - This is exclusively available in only CDMA technology.
