2G\/3G shutdowns is driven by the fact that operators have limited spectrum available for expansion. In order to provide a faster, more responsive network to their customers, they must re-use the spectrum with newer, more efficient cellular technology. Old 2G\/3G infrastructure makes way for new networks, 4G and 5G<\/p>\n
The good news is that 4G LTE will be available for at least a decade to come, and will co-exist with 5G networks.<\/p>\n
There has been some delay in shutting down 2G\/3G networks due to the amount of M2M\/IoT devices which utilise these services. 2G and 3G were ideal for applications with small, infrequent data requirements but IoT industry is now looking to next-generation LTE technologies such as Cat-1, Cat-0 and Cat-M1 as 2G, 3G (and eventually) 4G replacements.<\/p>\n
Number of 2G\/3G shutdown in 2020 and 2021<\/strong><\/p>\n During 2020, a total of 49 networks had been shutdown, of which 33 were 2G and 10 were 3G networks. The pace is accelerating and during 2021, an accumulated total of 75 networks will be shutdown, with 65% of them being 2G networks.<\/p>\n
