Who knows if this is merely testing or a planned change nationally in the future.”
Disclaimer: I don't work in the mobile industry, so this is just the supposition based on reading around here!
Three are very publicly declaring their difficulties with spectrum, so I'd imagine they're investigating how to make the most of their current allocation (as well as tugging on Ofcom's sleeve to try and fix the issue).
Since data forms a significant percentage of the traffic on their network and 4G is more spectrum-efficient than 3G (ie for a given Mhz band, you'd get more throughput filling it with 4G than 3G), I would not be surprised to see Three investigating ways to get all the 4G capable devices to use 4G as much of the time as possible.
I do wonder whether (if even possible) they're going to look to assign less spectrum to 3G, bidding farewell to DC-HSDPA+ in the process, and deploy some 4G2100. I would speculate that the heavy phone users will all be on 4G-capable devices now, therefore the amount of data required by those whose phones are only able to manage 3G is shrinking with every passing month.
The ultimate endgame here might well be their 4G1800 network as their main blanket coverage, like EE, with 4G800 for range and in building penetration, plus 4G2100 providing additional capacity - and an increasingly thin slither of 3G2100 to handle voice and (now slower) data from those without 4G capable handsets.
What do you folks reckon, do you think this sounds plausible? Or is it all a bunch of cobblers?
