Time Division Multiple Access (TDMA)
Each user is allowed to transmit only within specified time intervals (Time slots). Different users transmit in different time slots.
When users transmit, they occupy the whole frequency bandwidth (separation among users is performed in the time domain),
TDMA: Frame structure
TDMA requires a centralized control node, whose primary function is to transmit a periodic reference burst that defines a frame and forces a measure of synchronization of all the users.
The frame so-defined is divided into time slots, and each user is assigned a Time Slot in which to transmit its information.
