Its simplest form is with a single antenna, which works on WiFi (802.11b) standards anywhere in the world, and provides shared access to the PC, but also looks for other Meshbox installations in the neighbourhood. There's a second option; an additional, long-range antenna, which you can mount on the roof of your house, to pick up signals from other Meshboxes further away - across the village, perhaps.

What is really neat this that you can combine several broadband feeds (albeit at a 10% increase in wireless load).

There's a pioneer network at Kingsbridge in Devon, and there are trial sites in Macedonia, India, USA, the Netherlands, and of course, in several UK counties.

And the software is open source!
