Detailed explanation-1: -Time-division multiple access (TDMA) is a channel access method for shared-medium networks. It 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.

Detailed explanation-2: -4. Which of the following is not true for TDMA? Explanation: TDMA share a single carrier frequency with several users, where each user makes use of non-overlapping time slots. The number of time slots per frame depends on several factors, such as modulation technique, available bandwidth etc.

Detailed explanation-3: -Time Division Multiple Access (TDMA) is a digital modulation technique used in digital cellular telephone and mobile radio communication. TDMA is one of two ways to divide the limited spectrum available over a radio frequency (RF) cellular channel. The other is known as frequency division multiple access (FDMA).

Detailed explanation-4: -TDMA Frame The red, second, burst lasts 80 mS, so at a rate of 250kbit/s, site 2 sends 20, 000 bits per burst, or 20, 000 bits per second. The diagram shows a fixed time plan, where each VSAT has been allocated a predetermined portion of the total time. There is designed in 20mS guard period between each burst.
