Q. What is the difference between TDMA and FDMA?
TDMA is Time Division Multiple Access. In TDMA technology each user in the channel owns the channel bandwidth for some time in a round robin fashion. All GSM handsets use this technology.
FDMA is Frequency Division Multiple Access. In FDMA many users are allowed to transmit through the same channel at the same time. So each user at any particular time uses part of the bandwidth. CDMA handsets use this technology.
