Total Access Communication System
From Wikipedia, the free encyclopedia
Total Access Communication System (TACS) and ETACS are mostly-obsolete variants of AMPS which were used in some European countries (including the UK & Ireland). TACS was also used in Japan under the name Japanese Total Access Communication (JTAC).[1][1][2][2] It was also used in Hong Kong [3]. ETACS was an extended version of TACS with more channels.
TACS and ETACS are now obsolete in Europe, having been replaced by the GSM system. In the United Kingdom, the last ETACS service operated by Vodafone was discontinued on 31 May 2001, after sixteen years of service. ETACS is however still in use in a handful of countries elsewhere in the world. NMT is another analog cellular standard that was widely used in Europe, mainly in the Nordic countries, which has now been fully replaced by GSM except for limited use in rural areas due to its superior range.
