The arrival of 5G is scheduled for the year 2020 and will have some consequences beyond the technology itself, such as closing older networks to free up space in the spectrum for new ones. Every year we have news about the closure of 2G and 3G, the two "oldest" technologies that are still being used at this time. It is expected that 4G will function as a base while 5G is implemented and reaches a very high percentage of the population. now, We know that Movistars 3G already has an end date while at 2G no decision has been made.
In 2016, the information we were considering was that Spain should switch off 3G in 2025 and 2G by 2030. A little later, we saw that 3G will be shut down in 2020 and 2G by 2025 in Spain, earlier than expected. But we now have news that returns us to information from 3 years ago, at least in part. Marcos Sierra has confirmed in VozPopuli closing date for 3G on Movistar and also that 2G remains indefinite, although this latter we have clarified further with the own operator.
Close 2G networks and 3G Movistar: dates and decisions adopted
Movistar plans to close its 3G network by the year 2025. It is expected that at that time, 5G has already reached the vast majority of the populationwhile 4G will continue to improve and provide coverage for nearly 100% of the population. In this situation, it does not make sense to continue to maintain frequencies occupied by 3G to do the same as we would with 4G and 5G.
Currently, the 3G network is mainly used for voice calls and the use of data on this network has dropped. However the launch of 4G voice or VoLTE calling over the 4G network reduces its use. The use of the 3G network for both calls and data is expected to be back in 2025.
The case is something special in the case of 2G. Although it is an older technology, the date of its closure has not yet been decided. For now, this technology is maintained indefinitely until a decision is made. The reason is that it is the basis for it M2M (Machine to Machine) and IoT (Internet of Things) services and its replacement with 5G is not automatic.
