UK telecoms regulator Ofcom has published an update to its consultation on 5G, specifically the use of spectrum above 6 GHz to satisfy the anticipated bandwidth requirements that will prove too great for standard licensed spectrum.

Outlining the key questions addressed by the Call For Input (CFI), the document acknowledged the propagation challenges associated with higher frequencies but stressed there are technical solutions.

In this context the document subdivided these higher frequencies by noting that the propagation properties of all bands in the 10-100 GHz range have more or less equal characteristics. It was also noted that millimetre wave spectrum is good for backhaul.

As you might expect the document is pretty exhaustive and if you’re looking for a spot of holiday reading you can download it here. For those who lack the time/inclination/stamina the table below summarises the key blocks of spectrum identified by the CFI.

We are still very early in the 5G process, of course, but as the Ofcom document notes under ‘next steps’: “The information and analysis gathered from the Call for Input, related work and international developments will now inform our contribution to forthcoming international discussions. We will also undertake further analysis of potential bands, drawing on feedback from these international discussions.”
