1. Their abbreviation meanings actually give light to the manner they optimize channels. TDMA is short for Time-Division Multiple Access while CDMA is for Code-Division Multiple Access.
2. TDMA emerged and was utilized first. CDMA is the more recent technology gradually replacing TDMA.
3. TDMA chops or divides the channel into sequential time portions as each user has its respective right turn for channel use.
4. CDMA uses a process called Spread Spectrum '" scattering of digital bits in pseudo-random manner and collecting them for interpretation.
5. CDMA allows numerous users to use the channel at the same time while TDMA does not.
