. If your cellular went down,

Fibre optic link to world cut

need some protocol that shifts automagically to an emergency state when main/failover uplinks are lost.

I like radios. I do. But everyone already has a phone.

Most major cell sites have a primary fiber, buried in concrete so that they are backhoe-resistant. If they are really important, they will have a secondary fiber going a different route, so that one singe fiber cut doesn't take the site down. Often this one is not buried at all, but just strung up on a telephone pole. As long as these are still connected to something alive, and everything has power, they work. Some remote tower sites are connected by microwave dishes and daisy-chain several hops to the infrastructure.

we are 270km from a city, a single fibre optic link that travels across a fault line. There's lots of PTP airfibre links going in and out of the mountains, but we need something that will work when that fibre is down. an emergency sytem, located at the towers, that can communicate with its other nodes, and elect a boss node when the world is disconnected so that we get more than silence.

This is a software issue, really. some kind of failover routing
