The only way you'd get 100% coverage of 5G, is 100% coverage of full fibre FTTP throughout the UK
The only way you'd get ubiquitous 100% coverage of 5G, is (pretty much) ubiquitous 100% coverage of full fibre blanket ultrafast FTTP throughout the UK, due to the much smaller 5G cell coverage and the fact that at these frequencies, 5G signals don't penetrate buildings/metalized glass/insulation well (used extensively in modern buildings).
For 5G to remain cheap with the best coverage (future smaller 5G cells from streetlights etc) it will need to 'piggyback' dark fibre laid during public sector contracts like that just announced to connect Aberdeen's public buildings to full fibre.
Let's get clever here. Play BT at it's own game.
The City of Aberdeen could be clever here RIGHT NOW and stipulate changes to those contracts so they have long-term overall control over any additional dark fibre that is laid as part of this public funded contract, taking that ownership/control away from BT (assuming they carry out the contract).
The public sector needs to own and control this additional dark fibre, instead of leaving BT to control/delegate it's future use if we (the public) are paying to install it, as part of public sector rollout contracts.
5G is absolutely dependent on full fibre, deep into the UK network.
How are we going to ever achieve this now that the biggest operator BT/EE fixed/mobile data speeds are intrinsically linked, going forward, in truth, BT will be quite happy sitting on their hands, ignoring 5G, running EE as it is, with some 'cherry picked' G.fast to add to the fixed line mix, keeping everything else on their bamboozled, obfuscated copper carcass "up to" network.
It's plainly clear that BT and EE do not operate in distinct markets, they are intrinsically linked. 5G and full fibre fixed networks are reliant on one another.
But, the CMA stated BT and EE did operate in distinct markets as the basis of the allowing this merger. The utterly stupid decision by the CMA (Competition and Markets Authority), by technically incompetent folk that didn't understand the subtle technical issues here between future 5G mobile/fibre backhaul to connect those 5G cells.
And when Weasels Ofcom deliberately obfuscate this fibre optic backhaul requirement too, when they talk up the 5G spectrum auctions, what hope do we have?
I repeat, where is all this fibre backhaul Ofcom for 5G Bandwidth?
