Time Division Multiple Access : TDMA Assigning different time slots to different users

Time Division Multiple Access (TDMA) is a channel access method used in communication systems. Here’s the key idea:

A communication channel (frequency band) is shared among multiple users.

Instead of all users transmitting at once, the time is divided into slots.

Each user is assigned a unique time slot, during which only that user can transmit or receive.

After their time slot ends, the next user’s slot comes, and so on — in a repeating cycle.

📌 Example (Simple 4-user TDMA system):

Channel time is divided into 4 slots → Slot 1, Slot 2, Slot 3, Slot 4.

User A transmits in Slot 1, User B in Slot 2, User C in Slot 3, User D in Slot 4.

Then the cycle repeats continuously.

⚡ Key Points about TDMA:

Efficient when traffic is predictable.

Each user gets guaranteed bandwidth during their slot.

Used in 2G GSM mobile networks, satellite systems, and digital broadcasting.

Synchronization is crucial (users must stick to their slots).
