This is an Interesting, Though Likely Transitory Develpment
The Hong Kong protestors are using a peer-to-peer mesh broadcasting network that doesn't use the internet.
Is this like CB for cellphones?
I imagine that it could be jammed pretty easily, though actually eavesdropping on it might be a significant challenge, given good encryption.
Anyone here have any experience with these or thoughts on it?

It's sort of like CB if every radio was also a repeater that passed on everything it heard, and the distances involved were much smaller.

Propagation delays are horrible, volunteers supporting mesh nodes come and go, but relying on every peer does not work, vulnerable to disruption by intruder nodes, often jammed solid by congestion. At least in the U.S. every mesh is a stupid, predictable failure, unless it is bankrolled by an organization, but often even then. However, the idea continues to intrigue researchers. In Hong Kong the distances may be smaller and the mesh density greater than in typical American deployment. Also, it's temporary.

If you remember truly decentralized pirac... er... file-sharing network like Gnutella, eDonkey, etc., then you know what to expect from a mesh. BitTorrent crushed all of them because its performance was thousands times better, thanks to trackers. Trackerless torrents are still as bad as the old meshes and even Bram cannot do anything about it.
