The 2G/3G switch-off

The 2G and 3G networks across Europe are being shut down and replaced by 4G and 5G. Secure your communications to ensure your security and alarm systems continue to work.

The risk and impact

The phase-out of the copper, 2G, and 3G networks is in full swing. Connected devices that rely on these networks, ranging from fire and intruder alarms, to technical solutions for fault detection and monitoring, are in danger of failing. This means that intruder, fire or panic alarms will not be sent. It is important to replace outdated devices with new technologies today, otherwise your home or business may face serious consequences.

The 2G/3G switch-off timeline

The dates for switching off 2G and 3G networks aren't the same everywhere. Each country and provider sets their own timeline. In the UK, the networks have already started shutting down these older services to make room for faster, more reliable 4G and 5G signals. This shift is a big deal for anyone still using older tech, especially businesses with older systems that might suddenly lose their connection if they aren't updated. The timeline in the UK is as follows:

Vodafone and EE completed the 3G switch-off in early 2024.
Three completed the 3G switch-off in late 2025.
O2 will complete the 3G switch-off by early 2026.
All 2G networks will be switched off by 2033 at the latest, but some may close earlier.

A lot can be done already with 4G, but the big change comes with 5G. This technology has enormous capacity compared to the previous generations of networks, and it enables us to start using the Internet of Things to its full potential. This, in turn, opens up opportunities for much more creative solutions, which will give rise to a range of applications that we haven’t even heard of today (Marie Sandå, Portfolio Manager, Strategy & Partnerships IoT Connectivity, Telia, Sweden)

The technological shift

The total number of connected devices is difficult to estimate, but there is no doubt that there are many of them. In the alarm sector alone, there are hundreds of thousands of devices in every country that will be affected when the networks are shut down. The technological shift is happening all over the world. The decision as to which network should be turned off first (2G or 3G), and how to do so, depends on various factors that may vary according to the interests of individual telecommunications providers and geographic regions. Many countries have already shut down the older networks in favour of 4G.

Opportunities for the future

With modern 4G and 5G networks, it will be possible to use IoT in advanced communications ecosystems. By linking a large number of devices, you can gather the data needed to make smarter decisions and ensure any risks are caught in plenty of time. Analysis of events, locations, or equipment takes place faster and also becomes more accurate. With 5G, the capacity to transfer large amounts of data and the speed of transmission are significantly improved - it's a much more stable and secure communications system.

How can you and your business can prepare for the migration?

A full audit

Audit your devices and systems and identify anything using 2G or 3G.

Make a migration plan to avoid an emergency.

This gives you a better chance of streamlining the technology shift and making sure the transition is smooth, secure, and fast.

Be careful with details.

It is extremely important that it is done correctly, as it becomes extra critical when communications transitions to an IP-based solution and features are added.

Keep a high level of security at all times.

With more responsibility for cybersecurity, it's important to work with reliable suppliers and partners. This also becomes particularly critical when new features increase the risk of security breaches.

Choose a dedicated supplier with full knowledge of the technical challenges

Your service provider is your partner and someone you should be able to work with for a long time. And you want to get the best advice at every opportunity on which solutions work best when problems and possible new challenges arise.
