That would mean changing priorities and while they would indeed be getting close to EE for coverage, network performance would be dire!
Every single compatible device would be on it all the time.
The only way it would possibly work is if they put it on every mast like 3G is.
5Mhz 4G800 is roughly equivalent to 10Mhz DC 3G2100 for data throughput.
Trouble then is (I think I'm right in saying, someone correct me) that a dense 800 network would suffer reduced performance due to inter-cell interference (this is why 3G automatically load balances between cells (breaths or raises and lowers power)).
They can manually alter power levels but it's not very accurate when you are dealing with low frequencies.
The result would be really great coverage but less capacity than 3G and since Three 3G is already creaking in places, that would be a disaster.
800 absolutely must be backed up with some mid band spectrum on every mast where 800 is deployed.
Three are further screwed in that when EE I believe (we shall see), activate 800 on a mast, they will crank up the 1800 to near 2G levels and change CSFB to 2G.
This means 800 only has to fill that last 30% or so. (the relatively small area that 2G doesn't currently reach).
Plus, they have WiFi calling to take the load off 800 indoors.
Even if Three put 1800 on every mast it would have to be on low power (like now) for the foreseeable future and there's no WiFi calling meaning 800 would still have too big a gap to fill.
I honestly can't see a way out of this and I can't see the low priority 800 changing any time soon.
