2G refers to the second-generation of cellular network technology, which were rolled out globally starting in the early 1990s. The main differentiator to previous mobile telephone systems, retrospectively dubbed 1G, is that the radio signals of 2G networks are digital rather than analog, for communication between mobile devices and base stations.

Moreover, these newer technologies also targeted network coverage layers on low frequencies, further diminishing the potential advantages of Evolved EDGE. Coupled with the upcoming phase-out and shutdown of 2G mobile networks, it became very unlikely that Evolved EDGE would ever see deployment on live networks.
Next Generation Mobile Networks Alliance feels that 5G needs to be rolled out in 2021-2023 to meet business and consumer demands. [5] In addition to simply providing faster speeds, they predict that 5G networks will also need to meet the needs of new use-cases such as the Internet of things (IoT) as well as broadcast-like services and lifeline ...
Cellular network standards and generation timeline. This is a comparison of standards of wireless networking technologies for devices such as mobile phones.A new generation of cellular standards has appeared approximately every tenth year since 1G systems were introduced in 1979 and the early to mid-1980s.
The second mobile provider to shut down its GSM network (on 1 January 2017) was AT&T Mobility from the United States. [21] Optus in Australia completed the shut down of its 2G GSM network on 1 August 2017, part of the Optus GSM network covering Western Australia and the Northern Territory had earlier in the year been shut down in April 2017.

Personal Digital Cellular (PDC) was a 2G mobile telecommunications standard used exclusively in Japan. [citation needed] After a peak of nearly 80 million subscribers to PDC, it had 46 million subscribers in December 2005, and was slowly phased out in favor of 3G technologies like W-CDMA and CDMA2000. At the end of March 2012, the count had ...
Models aside from the 4G versions communicate on second-generation cellular networks only, rather than later standards such as 4G, and will no longer work when 2G networks are phased out, as has been happening since 2016 in different regions. These include: Nokia 105 (2013), released in 2013 and aimed at markets in developing nations. [1]
