Why should that use the internet though? There's low-power wireless communication technologies like Wifi HaLow that have a range of around 1km (0.6 miles), which would be totally fine for this use case. No internet needed.
Is that ubiquitous and does it go through walls? And what's the cost of that compared to existing solutions?
HaLow is sub-1Ghz so it goes through walls pretty well. Not sure about cost or how widespread it is yet.
