The technique, in which multiple phones take turns sharing a channel, does the global system for mobile communications (gsm) use is time division multiple access (TDMA).
<h3>What is TDMA in mobile computing?</h3>
The digital modulation method known as Time Division Multiple Access (TDMA) is used in mobile radio and digital cellular telephone communication. The limited spectrum that can be divided over a radio frequency (RF) cellular channel in one of two ways is called TDMA. Another is called frequency division multiple access.
Therefore, In order to allow multiple users to access the mobile system, GSM uses a variation of time division multiple access (TDMA) [5]. Using a type of frequency division multiplexing, CDMA implements its technology.
