@novenary @usernameswift @coolbean @rose emergency telephony needs 2g too under certain conditions, so do all calls when connected to 2g or 3g (and 4g and 5g if volte/vonr is broken/unsupported) 2g also has a much larger range compared to newer standards which does matter quite a bit if you are in the middle of nowhere and need help

@rose @novenary @usernameswift @coolbean there is a 30 year long tail of devices that do, but i don’t know how much relies on 2G data

@rose @novenary @usernameswift @coolbean mobile network-connected devices to this day are built to support it, so it would affect every device.
infrastructure improvements are built according to demand, of which there is largely none in huge swaths of uninhabited land without legal incentives.
shutting down 2g would leave already underserved communities completely without access to mobile telephony and mobile internet in addition of cutting off uninhabited areas too. it would be challenging to cover with modern infrastructure, and completely impossible with current capitalist incentives. (instead we get not just 3 but 4 independent network providers building in the same populated areas)
it might be okay to shut it down locally i suppose, in densely populated areas where the added capacity would benefit.
also no there are a bunch of regulatory hurdles to building your own cell network. especially once it has been shut down and the frequency assignment has been absorbed by 4G and 5G. it is also not possible to do it with just a rpi since it requires special hardware

@novenary @usernameswift @coolbean @rose my guess is that 6G is going to be like 5G, where it really only matters in very dense urban areas
