Hams have been messing about with mesh for some time. It's referred to as ARDEN. And the slick part of it is it can be as small or large as desired and that you have equipment for. I am right now sitting in the building were a node exists that has 120 sectors on 900, 2.4, and 5.8 on all four sides of the tower at 190 feet. The site links cover 4 other counties and will be 5 counties next year. Now, this is a big site. But the same gear can be deployed on 20 foot masts and will link between those masts and provide coverage to anyone licensed with the right gear. And I would defy ANYONE that believes they can send documents (files) via CW nearly as fast as we can with this system. The system as a whole offers chat, web services, email, FTP, IPphone and just about anything else that you would need. And by design, if a site or node fails, the other nodes will route around that site and continue passing traffic. Not sure but I don't think Bao Feng offers that option
