I've been thinking about an idea, that maybe it would be worthwhile for a city to create a wireless network where it uses rooftops for a mesh.
This WiFi offers a low-data-rate (<5-10 mbit/s) service to seniors for free or a very low fee (~3€/month), without service guarantees, but honest best-effort.
In the case when an internet problem arises, which affects the city's it-infrastructure, the city can switch to this WiFi to have their city-wide services still interconnected, while the seniors get kicked off of the network during this time.
