Only realised the other day that Vodafone had 4g-2g switching, put my LG G4 into 2g/4g mode then tried to make a call, it worked fine and dropped back to 4g once finished. It also switched over to 2g fine when I received a call, for some reason I didn't think this was possible, my next thought was if it is clearly possible why is 4g coverage limited to we'll under 900mhz 3g areas instead of just under 900mhz 2g? Seems a waste of such a great new technology to limit it in such a way, plus surely the 2g fallback would only apply to those users outside 900mhz 3g but still with 2g so the demand would be any greater on the old tech. 😕”
It is possible to do CSFB to 2G. Vod would find this easier than EE since their 2G network is set up for handling a lot of 2G calls anyway.
EE's isn't since most calls go over 3G and I suspect they want to bring some more 1800 over to 4G at some point.
Perhaps Vodafone are doing it to 2G where their 2G kit is new enough.
Still means the 800 has to be slightly restricted on power to stay within 2G's fixed 900 footprint, but no where near as bad as keeping it within 2100.
I still think EE and Three will have an advantage in coverage ultimately since their 800 can be cranked up to 11 and they have a denser network.
Although I think CTIL will eventually have nearly as many masts as EE.
