Time Division Multiple Access (TDMA) is
|“||a technique that allows many users to share the same radio spectrum by transmitting information in different time slots.||”|
TDMA is also used to refer specifically to the standard covered by IS-136, which defines a specific type of cellular network. Using the term TDMA to refer to a general technique or a specific type of cellular network can be a source of confusion. For example, although GSM uses a TDMA air interface (i.e., the general technique), as does iDEN, neither of those systems is compatible with so-called TDMA cellular networks that follow IS-136.
