First Generation

Advanced Mobile Phone Service (AMPS) US trials 1978; deployed in Japan (79) & US (83)

800 MHz band two 20 MHz bands

TIA-553

Still widely used in US and many parts of the world

Nordic Mobile Telephony (NMT) Sweden, Norway, Demark & Finland

Launched 1981; now largely retired

450 MHz; later at 900 MHz (NMT900)

Total Access Communications System (TACS) British design; similar to AMPS; deployed 1985

Some TACS-900 systems still in use in Europe

GSM (2G)

Groupe Special Mobile , later changed to Global System for Mobile

Joint European effort beginning in 1982

Focus on seamless roaming across Europe

Services launched 1991

Time division multiple access (8 users per 200KHz) 900 MHz band; later extended to 1800MHz

Added 1900 MHz (US PCS bands)

GSM is dominant world standard today

Well defined interfaces; many competitors

Network effect (Metcalfes law) took hold in late 1990s

Tri-band GSM phone can roam the world today
