Mesh Networks / by john cheng

I just learned about mesh networks. This is really cool concept.

Mesh networks are small, standalone communications exchanges that rely on phones (or other devices) talking directly to each other, with their range sometimes amplified through line-of-sight routers or other extenders. These hyper-local area networks can have a link to the outside Internet, but they don’t always need it to accomplish their central aims: local communications in spite of natural disaster or political suppression.
