How to handle the vanishing radio spectrum: Share frequencies

By Patrick Nelson

With the billions of Internet of Things (IoT) devices projected to come on-stream over the next few years, questions are arising as to just where the bandwidth and radio channels are going to come from to make it all work.

The sensors need to send their likely increasingly voluminous data back to networks wirelessly to be processed.

But there’s a finite amount of radio spectrum available, and much of it is already allocated to incumbent primary users, such as public safety agencies. Other spectrum is dedicated to mobile network operators who have licensed chunks of it. Some is leftover in the millimeter frequencies, which is thus far pretty much untested in the real world — it’s going to be used for 5G in the future.
