I really wish standards like WiFi simply covered more usecases like this. All it would take is a few extra modulation and coding modes in the standard.
I should be able to walk 5 miles from my house, and still have my house wifi work, but at a data rate of 0.3 kbps.
I should never have wifi 'cutting in and out' or 'on the edge of the range' - it should be a simple matter of not being fast enough if I'm too far away. If Shannon[1] allows it, the standard should allow it too.
Obviously my phone would probably choose to switch to mobile data long before that. But for some use cases, like instant messaging, 0.3 kbps is fine, and there shouldn't be a need to use a totally different standard to achieve it.
