Re: Are you really expecting Nationwide 5g coverage at all?
The lowest frequencies being deployed in the UK for 4G is 800Mhz, the lowest for 5G is 700Mhz. 5G also has a lot of improvements in regards to spectral efficiency over 4G.
So theoretically it should be easier to provide rural coverage with 5G then with 4G.
What is really needed is legislative changes though. The UK has the lowest height restrictions for mobile towers in Europe AND you are not allowed to make towers taller then the treeline (can somebody inform parliament that trees grow).
