Saying goodbye to legacy networks, but what's next for IoT?
This report is available to those subscribed to the IoT & Enterprise module.
The pace of 2G/3G network shutdowns is increasing as operators look to optimise their network operations and costs, and to refarm spectrum for 4G and 5G. Most recently, Telefónica Deutschland (O2) announced it is accelerating the shutdown of its 3G network in various regions of Germany. Based on announced plans from operators, at least 64 networks will be shut down between 2021 and 2025. In fact, 2021 is set to be the year with the highest number of 2G and 3G network shutdowns so far. While migrating voice users onto 4G and 5G networks can be achieved more easily via marketing and awareness campaigns, M2M/IoT devices are another matter. Oftentimes these devices have a long device lifecycle and are in hard-to-reach locations, making the upgrade process troublesome.

Made for IoT Summit 2025: key takeaways from the show
Earlier this month, Onomondo hosted the Made for IoT Summit 2025, bringing together a mix of IoT developers, device OEMs, module makers and adopters from across the IoT ecosystem, under the motto 'IoT connectivity should never be a bottleneck'. Key themes discussed included the latest GSMA eSIM SGP.32 and SGP.31 specifications, how the ecosystem is getting ready for commercial launches and the impact to connectivity service providers and device makers. Non-terrestrial networks IoT was a topic of focus as well, with the event’s participants taking note of progress being made and expressing high expectations for further advancements in the low Earth orbit space that will help drive greater adoption and lower costs. Finally, a new flagship private wireless project was unveiled in detail: Onomondo’s implementation with Maersk, Nokia and a suite of other partners that will bring private wireless to 450 ships at sea.
