• In TDMA, the bandwidth of channel is dividend amongst various stations on the basis of time.

• Each station is allocated a time slot during which it can sent its data i.e. each station can transmit its data in its allocated time slot only.

• Each station must know the beginning of its slot and the location of its slot.

• TDMA requires synchronization between different stations.

• Synchronization is achieved by using some synchronization bits (preamble bits) at the beginning of each slot.

• TDMA is different from TDM, although they are conceptually same.

• TDM is a physical layer technique that combines the data from slower channels and transmits then by using a faster channel. This process uses physical multiplexer.

• TDMA, on other hand, is an access method in the data link layer. The data link layer in each station tells its physical layer to use the allocated time slot. There is no physical multiplexer at the physical layer.
