What happens when 20 very funky wirless meshcubes supplied by 4G Systems get together with Andreas Tønnesen, the author of a fresh implementation of a mesh routing protocol called Optimised Link State Routing (OLSR)?
Why, mesh madness at the Wizards of OS conference of course!!

The network consisted of 3 rooftop meboxes together with various indoor units providing a stable backbone, with multiple roaming meshboxen (in cars, on foot, and on rollerblades!!) filling the gaps of coverage between the Berlin Conference centre, and c-base (the oldest crashed spaceship on earth!). The topology diagram represents the self-formed routing mesh between each meshbox.
the amazing tiny meshbox
Each tiny meshbox features 2 wireless interfaces, one to join the MANET mesh, and the other used as a classic access point for non-meshed wireless clients (essid: freifunk.net).
The mesh works suprisingly well, although Andreas has his work cut out in some debugging, as some members of the OLSR mesh occasionally lost their routing tables causing the mesh to briefly lose contact now and again.

A wireless survey utilising kismet and a GPS unit gave a good indication of the area covered.
