HInternet
Overview
The amateur radio service has a good chunk of the Internet address space, and it's not being used for its intended purpose: a worldwide packet radio network. Meanwhile, the rest of the Internet is crowding into the remaining address space and will no longer have any left in the near future.
It's a chicken-and-egg problem: the necessary digital repeaters aren't available for users, and there are no users to justify building the repeater network.
The cost of the equipment has finally come down to the point where even a modestly funded amateur radio club can afford to set up a small regional network by themselves. Through advocacy and standards development, Noisebridge is building a packet radio network modelled on the original vision of the Hinternet.
Network Architecture
The radios will be 802.11-based HSMM gear.
There are three major bands suitable for use by hams transmitting spread spectrum: 420-430 MHz, 2.4 GHz, and 5.8 GHz.
