(Total Access Communication System) An earlier analog cellular phone system deployed mostly in Europe and modeled after the AMPS system in the U.S. In the U.K., ETACS (Extended TACS) transmitted in the 871-904/916-949 MHz band, and International TACS (ITACS) and International ETACS (IETACS) operated outside the U.K. Narrowband TACS (NTACS) used the 860-870/915-925 MHz band and a narrower channel spacing that delivered more channels in the same amount of spectrum. See AMPS.


(Advanced Mobile Phone Service) The primary analog cellular mobile phone system deployed in North and South America and more than 35 other countries. It used FDMA transmission in the 800 Mhz band. The first AMPS system in the U.S. was deployed in Chicago in 1983. See N-AMPS, NMT and TACS.
