The future of mobile networks already has a date to leave the past behind, specifically 2G.
And this is what the UK government has warned. The definitive shutdown of 2G will occur between 2029 and 2033which could put out of service many older devices that still work with this technology.
This should not come as a surprise, in fact all operators have already begun to eliminate previous networks such as 3G in a progressive process to modernize mobile infrastructure.
This mainly affects to old mobiles that only operate with 2Gwhich will lose the ability to make calls, send messages or connect to the Internet. For most users, The impact will be almost imperceptible, since modern mobile phones comply with these standards.
In any case, the British authorities have recommended checking the compatibility of current devices and consulting with the operators in case of doubt.
Beyond mobile phones, the notice also affects other connected devices that could go unnoticed, such as alarm systems, fire detectors or medical devices that depend on 2G networks.
According to the industry, the latest technology not only improves the speed and reliability of connections, but also reduces energy consumption. Specifically, 5G can be up to 10 times more efficient than 3G.
This UK case is not isolated; other countries have already started a similar process and are finalizing their own shutdown schedules.
