1G refers to the first generation of mobile telecommunications standards, introduced in the 1980s. This generation was characterized by the use of analog audio transmissions, a major distinction from the subsequent 2G networks, which were fully digital. The term "1G" itself was not used at the time, but has since been retroactively applied to describe the early era of cellular networks.
During the 1G era, various regional standards were developed and deployed in different countries, rather than a single global system. Among the most prominent were the Nordic Mobile Telephone (NMT) system and the Advanced Mobile Phone System (AMPS), which were widely adopted in their respective regions.[1] The lack of a unified global standard resulted in a fragmented landscape, with different countries and regions utilizing different technologies for mobile communication.
As digital technology advanced, the inherent advantages of digital systems over analog led to the eventual replacement of 1G by 2G networks. While many 1G networks were phased out by the early 2000s, some continued to operate into the 2010s, particularly in less developed regions.
