Mobile signal remains spotty in Southampton, I’m unable to use 5G at home because I’m in the dead zone between the coverage of three masts. That’s less of an issue in recent years though because the terribly named “toob” have rolled out fibre across most of the city, and will sell me a line doing a gigabit up and down for £25 a month, which is less than I was previously paying for DSL over a bit of wet string.
Probably council rejecting new masts if it is like most places in the UK.
3UK have thousands (maybe 10k?) new masts in planning to really improve 5G coverage (and they have the spectrum to actually deliver 2gig/sec to phones in the real world). Annoyingly the (vast in many cases) majority will are being rejected on suprious grounds by the council.
The reality where I live (North of England) is the opposite: cash-strapped (and often greasy-palmed) councils will approve masts willy-nilly, to the annoyance of locals who find out only after they're erected. Very occasionally this generates any actual organised blowback.
I'm curious, what are the actual objections to mobile masts being erected? They don't make a noise, they're not (despite the conspiracy theorists) in any way dangerous. All I can think of is that people don't like the way they look, but I don't really see them as being any uglier than a lamppost or street sign.
Mainly aesthetics, the new 5G masts are much larger and need to be sited in densely populated areas where there is already a significant amount of unwelcome street furniture.
Conspiracy theories regarding harmful radiation can also be a factor.
