RTMI
RTMI (Radio Telefono Mobile Integrato) was the first mobile communication service in Italy, started in 1973. It operated on the 160 MHz frequency band and was used by a few people working in the public sector (public administrations and defense officials). In the 1980s, the Radio Telephone Mobile (RTM) emerged, which operated on the 450 MHz frequency band and attracted 100,000 customers. The cellular standard RTMS was launched in 1985. In 1989 the SIP (Società Italiana per l'Esercizio delle Telecomunicazioni) adopted the TACS Total Access Communication System (TACS) and ETACS are variants of Advanced Mobile Phone System (AMPS) which were announced as the choice for the first two UK national cellular systems in February 1983, less than a year after the UK government an ... standard. RTMS services were switched off in 1996. References Mobile technology {{Wireless-stub ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Total Access Communication System (TACS) and ETACS are variants of Advanced Mobile Phone System (AMPS) which were announced as the choice for the first two UK national cellular systems in February 1983, less than a year after the UK government announced the T&Cs for the two competing mobile phone networks in June 1982. This 1G technology is now obsolete. History 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, United States. 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.
