{{main|Digital AMPS}}
Later, many AMPS networks were partially converted to [[D-AMPS]], often referred to as '''TDMA''' (though [[time-division multiple access|TDMA]] is a generic term that applies to many 2G cellular systems).  D-AMPS, commercially deployed since 1993,<ref>Anton A. Huurdeman, [https://books.google.com/books?id=SnjGRDVIUL4C&dq=d-amps+tia+history&pg=PA533 The Worldwide History of Telecommunications], John Wiley & Sons, 31 juli 2003, page 533</ref> was a [[Digital data|digital]], [[2G]] standard used mainly by [[AT&T Mobility]] and [[U.S. Cellular]] in the United States, [[Rogers Wireless]] in Canada, [[Telcel]] in Mexico, [[Telecom Italia Mobile]] (TIM) in Brazil, [[VimpelCom]] in Russia, [[Movilnet]] in Venezuela, and [[Cellcom (Israel)|Cellcom]] in Israel.  In most areas, D-AMPS is no longer offered and has been replaced by more advanced digital wireless networks.
