What is the current state of 4G technology?
The current state of 4G technology is that it is still widely used and supported by most mobile networks around the world. However, with the increasing adoption of 5G technology, the focus has shifted towards the development and deployment of 5G networks. Many mobile operators have already started to phase out their 2G and 3G networks, and some have also begun to reduce their investment in 4G infrastructure.
Despite this, 4G technology is still expected to play a significant role in the coming years, particularly in areas where 5G coverage is limited or non-existent. Many mobile operators are also exploring ways to upgrade their existing 4G networks to support new use cases and applications, such as IoT and mission-critical communications.
Will 4G be phased out completely?
It is unlikely that 4G will be phased out completely in the near future. While 5G technology is gaining traction, there are still many areas where 4G coverage is the only option. Additionally, many devices, including smartphones and IoT devices, still rely on 4G connectivity.
