The Wireless Corner is an international gathering area for wireless community networking.

At the 23 chaos communication congress in Berlin the Wireless Communities will setup a place for gathering and hacking during the 23c3. We will be playing with a lot of toys -- wireless routers, home-built antenna, soldering irons, 3d visualisation software of mesh networks and other funny 802.11 stuff.

The Wireless Corner is located round the stairs at floor C02, same place like last year... ;-)
