Synchronization in TDMA

• Notice that a ``clock'' is required for TDMA.
• All transmitters and receivers must be aware of this ``clock'' to schedule their transmissions and receptions.
• We say that transmissions are synchronized.
• In cellular telephone systems a clock signal that indicates the beginning of time-slots is transmitted by the base stations. From this signals, mobile stations can determine when their turn comes up.
• In the digital telephone system, the transmitting exchange sends synchronization information together with the conversations.
