Time Division Multiple Access (TDMA)

In the cases where continuous transmission is not required, there TDMA is used instead of FDMA. The features of TDMA include the following.

• TDMA shares a single carrier frequency with several users where each users makes use of non-overlapping time slots.
• Data transmission in TDMA is not continuous, but occurs in bursts. Hence handsoff process is simpler.
• TDMA uses different time slots for transmission and reception thus duplexers are not required.
• TDMA has an advantage that is possible to allocate different numbers of time slots per frame to different users.
• Bandwidth can be supplied on demand to different users by concatenating or reassigning time slot based on priority.
