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. This allows multiple … See more • Shares single carrier frequency with multiple users • Non-continuous transmission makes handoff simpler • Slots can be assigned on demand in dynamic TDMA See more 2G systems Most 2G cellular systems, with the notable exception of IS-95, are based on TDMA. GSM, D-AMPS, PDC, iDEN, and PHS are examples of TDMA cellular systems.
