Berlin OLSR Wireless Mesh Testbed at Wizards of OS 3

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!!

snapshot of Berlin MANET mesh (click for detail)

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:

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.

Possible UK bulk buy of meshcube's 5.00 (#1)
by Anonymous Hero on Tue Jun 29th, 2004 at 20:15:28 GMT

Rixter is considering making a bulk purchase of meshcubes. Those of you who attended DMZ at Limehouse last year will have seen this nice little dual-radio mesh router/bridge/access point device. Send email to with something like "Yes - definitely", "Maybe - depending on the price you get", or "probably not, but keep me posted" in the subject line.

This is an example of showing ingenuity. Already cellphones exist for making cellular communications with their complete set of towers. So why the need for a meshed communication system or wi-Fi hot spots. But what is needed is the development of technbology that will make it unnecessary for the servers to send documents to the clients upon the receipt of a request therefor from the client as discussed at When this technology is developed people will not need to buy laptops and cellphones. Only cellphones will do.

Will this kind of thing be happening in Canada?

It's truly amazing that this mesh thing is working. It will be very interesting to see what it'll be like when he's finished with the project.
