History of TDMA/GSM

TDMA (Time Division Multiple Access) used in the United States as a name for the mobile phone standard more properly referred to as IS-136 or D-AMPS. Although this system is most often referred to as TDMA, includes GSM, as well as in IS-54 and IS-136. The two different uses of this term can be confusing. TDMA (the technique) is also used in the GSM standard. However, TDMA (the standard, i.e. IS-136) has been competing against GSM and CDMA (systems based on Code division multiple access) for adoption by the network carriers, although IS-136 is now being phased out in favor of GSM technology.

IS-54 and IS-136 are second-generation (2G) mobile phone systems, known as Digital AMPS (D-AMPS). It is used throughout the Americas, particularly in the United States and Canada. D-AMPS is considered end-of-life, and existing networks are in the process of being replaced by GSM/GPRS and CDMA2000 technologies.
