If you’re working within the IoT industry, you’ll be no stranger to the fact that 2G and 3G networks have started to go through a transition of sunsetting. We wanted to share some important information that could help your business prepare for this change – including a comprehensive list of which networks are planning to close their networks, and when.

Why are 2G and 3G networks being turned off?

With the advent of 4G and the subsequent emergence of 5G networks, the demand for faster and more reliable wireless communication has skyrocketed. The decision to sunset 2G and 3G networks stems from the need to allocate resources and network capacity towards these newer technologies. By retiring older networks, network operators can repurpose the spectrum, optimise efficiency, and pave the way for the next generation of wireless connectivity. 

What are the benefits of sunsetting these networks?

The decision to sunset 2G and 3G networks brings several benefits to both network operators and consumers. By retiring outdated technologies, operators can streamline their networks, reduce maintenance costs, and better utilise limited resources. This transition also allows them to focus on expanding and optimising newer networks like 4G and 5G, which offer faster data speeds, lower latency, and enhanced connectivity.

What is the timeline for 2G and 3G sunsetting?

The sunsetting of 2G and 3G networks has been underway for some time now. While the exact timeline may vary depending on the country and network operator, the process typically began around 2017-2018. Since then, operators have gradually been phasing out these networks to reallocate resources to more advanced technologies.

By the end of 2025, support for 2G/3G worldwide will be almost non-existent and so IoT businesses must be prepared so that their services remain unaffected. OV can help remove that stress and future-proof your IoT technology, to learn more speak to our team today.
