Total Access Communication System (TACS) and ETACS are mostly-obsolete variants of Advanced Mobile Phone System (AMPS) which was announced as the choice for the first two UK national cellular systems in Feb 1983, less than a year after the UK government announced the T&Cs for the two competing mobile phone networks in June 1982. Vodafone (known then as Racal-Vodafone) opted for a £30 million turnkey contract from Ericsson (ERA) to design, build and set up its initial network of 100 base station sites.

  • Total Access Communication System (TACS) ist ein Standard für analogen Mobilfunk. TACS ist die europäische Version von AMPS. ETACS ist eine erweiterte Version von TACS mit mehr Kanälen. TACS und ETACS wurden in Europa durch GSM ersetzt. In Großbritannien wurde das letzte ETACS-Netz von Vodafone am 31. Mai 2001 abgeschaltet. Es war 16 Jahre lang in Betrieb.

  • Total Access Communication System (TACS) and ETACS are mostly-obsolete variants of Advanced Mobile Phone System (AMPS) which was announced as the choice for the first two UK national cellular systems in Feb 1983, less than a year after the UK government announced the T&Cs for the two competing mobile phone networks in June 1982. Vodafone (known then as Racal-Vodafone) opted for a £30 million turnkey contract from Ericsson (ERA) to design, build and set up its initial network of 100 base station sites. Cellnet (then known Telecom Securicor Cellular Radio Ltd) used development labs in the facilities at General Electric (later made part of Motorola) based at Lynchburg, Virginia, USA. The reason Cellnet used the General Electric labs was because the AMPS system was already in development there, and the company had set up a production facility in readiness for AMPS production in 1985 which the Cellnet TACS was to share. In March 1984 development of prototypes began at General Electric. Production began in 1985 and General Electric produced 20,000 systems that year for Cellnet's distribution in the UK. Production of what was to become the Motorola model were then made at Stotfold, Bedfordshire, England. This production facility continued making TACS until the advent of GSM. TACS cellular phones were used in Europe (including the UK, Italy & Ireland) and other countries. TACS was also used in Japan under the name Japanese Total Access Communication (JTAC). It was also used in Hong Kong. ETACS was an extended version of TACS with more channels. TACS and ETACS are now obsolete in Europe, having been replaced by the GSM (Global System for Mobile Communications) system. In the United Kingdom, the last ETACS service operated by Vodafone was discontinued on 31 May 2001, after 16 years of service. The competing service in the UK operated by Cellnet (latterly BT Cellnet) was closed on Sunday 1 October 2000. Eircell (now Vodafone Ireland) closed its TACS network on 26 January 2001. This followed a long period during which customers were encouraged to switch to GSM services. When the network was closed, there were very few, if any, active TACS customers left. Customers who switched network were able to keep their phone number, but the (088) prefix was changed to either 087 (Eircell, now Vodafone Ireland) GSM or 086 (Esat Digifone, now O2 Ireland) GSM. At the time, full mobile number portability was not available to TACS customers and the (088) prefix was closed. An automatic voice message was left in place for 12 months advising callers of the customer's new prefix. ETACS is however still in use in a handful of countries elsewhere in the world. Nordic Mobile Telephone (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.

Il TACS, introdotto in Italia nel 1990 dalla SIP, ha cessato di funzionare nella notte tra il 30 e il 31 dicembre 2005 ed ha così ceduto le sue frequenze radio al GSM. Il TACS deriva dal sistema statunitense Advanced Mobile Phone System ed è stato utilizzato prevalentemente in Europa. In Italia l'importanza del TACS è stata essenzialmente quella di aver consentito la rapida diffusione della telefonia mobile.

Эксплуатация последнего фрагмента этого типа сетей в Великобритании была прекращена 31 мая 2001 года (оператор Vodafone). Полоса частот на передачу БС 935—950 МГц (917—933 ETACS), МС 890—905 МГц (872—888 ETACS). Разнос речевых каналов 25 кГц. Общее число каналов 600 (640 ETACS). Тип модуляции FSK. Радиус ячейки 2-20 км. Время переключения на границе ячейки до 290 мс. Сети этого стандарта были развёрнуты в Кении, Кувейте, Макао, Малайзии (оператор Celcom (англ.)), Мальте, Нигерии, Филиппинах, Сингапуре, Испании (оператор Telefónica) Йемене, Заире, Турции и некоторых других странах. Вариант системы, JTAC также использовался в Японии и Гонконге.
