Freifunk (German for Free Radio) is an initiative to support the development of tools for free mesh networks. Besides that the initiative supports communities developing know-how to set up their own networks.

The freifunk community is is part of a network of projects developing tools for mesh networks including the Freifunk Firmware and OpenWrt projects, routing protocols such as OLSR and B.A.T.M.A.N., tools like Maps for networks (e.g. freimap), scanning tools like the horst tool and many more. Recently people also started to develop Open Hardware like the Mesh Potato for villagetelco. With the freifunk firmware it is relatively easy to bring up new wireless mesh networks using ad-hoc WLAN communication layer 2 and layer 3 routing with OLSR, BATMAN and other protocols. Originated in Germany, Freifunk has been deployed successfully in many countries. The OLPC project in Afghanistan uses freifunk for its mesh deployments to distribute digital books, news and educational media. In Ghana freifunk is used to bridge the digital divide in villages. In Vietnam freifunk is used to offer Internet connections at Free and Open Source events like FOSSASIA. In Europe and the Americas city and village networks lower costs for communities and small and medium sized companies, that share common Internet connections, ADSL, Telephone or Satellite uplinks in remote regions.
