1G refers to the first generation of cellular network (wireless) technology. These are mobile telecommunications standards that were introduced in the 1980s and were superseded by 2G. The main difference between these two mobile cellular generations is that the audio transmissions of 1G networks were analog, while 2G networks were entirely digital.
There were many different 1G cellular standards developed and used in different countries, but the most widely adopted globally were the Nordic Mobile Telephone (NMT) and Advanced Mobile Phone System (AMPS) systems.[1] The inherent advantages of digital technology over that of analog meant that 2G networks went on to eventually completely replace them. Many 1G networks were switched off in developed economies by 2000, but in some places networks continued to operate into the 2010s.
