I sort of agree. Vodafone in UK very rarely bothers deploying LTE2600 unless it is a super busy place like a train station. They rely mostly on LTE800, they've started doing LTE2100 as 800 is getting so congested. But they're not even bothering with the high frequency bandwidth they already have; so I really can't see them bothering with even higher and more expensive to deploy spectrum (again, unless it is super crowded places, but LTE2600 with micro/pico cells can handle this really well now). I also noticed the same in the US when I was roaming, even in lower manhattan there was a load of LTE700 and only sporadic higher spectrum LTE1700/2100. I think LTE with loads of carrier aggregation will work just fine, I can't see this being much of a step. Apart from maybe better handoff between networks; but it isn't suddenly going to enable a new load of applications/devices like it is being hyped up for.
