Gartner Glossary

First Generation (1G or Analog)

Wireless networks based on analog frequency division multiple access technologies. Many systems were individually tailored, country-specific solutions, including technologies such as AMPS, Nordic Mobile Telephone (NMT) and total access communications system (TACS). Although these were the first generation of mobile telephony, they are never referred to as “1G.”
