What is Tdma?
1.
Time Division Multiple Access
A method of digital wireless communications transmission allowing a large number of users to access (in sequence) a single radio frequency channel without interference by allocating unique time slots to each user within each channel. Rather than encoding bits of data like CDMA, each frequency is broken into time slots through which bits of data flow. Data can only flow in their assigned time slots.
Cellular (mobile) Phones use
CDMA ,TDMA ,analog , orGSM for radio (voice) transmission as well as wireless internet connections.
