Following the discussions around Mobile World Congress this year, one phrase keeps appearing in industry commentary: IoT connectivity is becoming distributed digital infrastructure. It’s an interesting idea; but if you’ve been around the IoT industry long enough, it also sounds familiar because for the 15-20 years the industry has repeatedly announced the technology that would define IoT connectivity. We've had the early days of cellular data, the LPWAN wave, a long list of competing technologies all promising to become the standard, then mobile operators responded with their own standards and NB-IoT was born; we've had alternative approaches, community-built networks, large-scale mesh architectures, and countless IoT platforms promising to simplify everything. The result? Not one universal connectivity solution but a complex landscape of overlapping technologies.

A new narrative

Today the conversation is changing; instead of focusing on new radio technologies, the industry is increasingly talking about network architecture. The idea is that IoT connectivity will evolve into a form of globally distributed infrastructure, where network functions are deployed across multiple regions and traffic is processed closer to devices rather than routed through a single central network. The theory is this brings several benefits:

• Lower latency
• Greater resilience
• Easier compliance with data sovereignty regulations

This architecture starts to resemble how the internet itself operates, with infrastructure distributed across many locations.

But is it really happening?

This is where the story becomes less clear. Much of today’s “global IoT connectivity” is still delivered by orchestrating existing mobile networks through software platforms, devices connect to traditional operator networks, while connectivity platforms manage roaming, switching, and device provisioning across those networks. It’s a powerful model, but it raises an important question. Are we actually building distributed connectivity infrastructure or are we simply building smarter ways to manage the networks that already exist?

The industry may be somewhere in between

There are genuine changes happening, regulation is forcing organisations to think carefully about where data is processed, global deployments are exposing the limitations of traditional roaming models and enterprise IT teams are increasingly treating IoT networks as part of their broader digital infrastructure; still, much of the innovation still appears to sit above the network layer, rather than fundamentally changing how the underlying infrastructure is built.

So what’s the real shift?

Perhaps the industry is simply moving through another phase of experimentation, the last decade has shown that IoT connectivity was never going to converge on a single universal technology instead, it may evolve into a layered ecosystem, where multiple networks, platforms and protocols work together. If that’s the case, the real shift happening now may not be technological, it may be architectural.

The real question isn’t whether distributed IoT connectivity is possible, it’s whether the industry is actually building it or just talking about it again.
