TDMA is a wireless system for shared-medium networks allows several users to share the same frequency channel by dividing the signal into different time slots. The users transmit in rapid succession, one after the other, each using its own time slot allows multiple stations to share the same transmission medium while using only a part of its channel capacity.
TDMA system divides the radio spectrum into time slot only one user is allowed to transmit or receive.

Features of TDMA
- Guard time needs to be minimized.
- The transmission rate is high adaptive equalization is necessary.
- Shares a single carrier frequency with multiple users.
- Data transmission occurs in bursts.
- Frequency/slot allocation complexity.
- Slots can be assigned like demand in dynamic TDMA.
- Less stringent power control.
- Non-continuous transmission makes handoff simpler.
- Cell breathing is more complicated.
- Pulsating power envelop & Interference with other devices.
- Low battery consumption because the transmitter of the subscriber can be turn off when it is not in use.
- A different time slot for transmission and reception so that duplexes are not required mostly in this system.
