5G is Just Rolling Out. So What's 6G?

When the city of Oulu, Finland, invited a group of journalists to come and have a look at some of the work that they are doing to initiate research on 6G, I (like many I have spoken to) immediately thought, But we don’t even have commercial 5G yet, so how can we be talking about 6G?

But once I got there, I began to realize that it’s just a marker — most of the work going on in Oulu, as in the rest of the world, is in rolling out 5G, carrying out trials, and figuring out business models and use cases. As the head of Nokia’s supply chain told us, it is already shipping millions of its Airscale radio access platform for 5G installations in cities around the world.
