The next generation of wireless communications is on the horizon, and the telecoms world is waiting to see exactly at which frequencies 5G will be implemented. Despite some unknowns and technological challenges, it is increasingly becoming clear that millimeter-wave (or millimeter band) will be a key enabler for 5G and it is going to be deployed in very early 5G use cases such as 5G fixed wireless. In this article, we explain the benefits of the different wave frequencies and delve into the activities of the key stakeholders who are shaping the 5G future from a new radio spectrum perspective.
