Freifunk is a non-commercial initiative for free and open wireless networks.

We act as umbrella organisation for other wireless communities like Ninux,, or WLAN Slovenija and communities developing software we extensively use like OpenWRT, OLSR, BATMAN, libremesh or retroshare.

Individuals from such local communities develop software to their own needs and provide those on their websites. There are more and more open community networks that meet regularly across villages and cities all over the world.

Hardware and Software

Most devices in our networks are based on off-the-shelf devices such as WiFi routers for home networks. The freifunk operating system is based on the OpenWrt Linux distribution for embedded devices. Additionally, the distribution contains several extensions for wireless mesh networking. Our local communities contribute to a wide range of different software projects focusing on ad-hoc software services, routing and network protocols, monitoring systems and visualization solutions. For instance, actively developed packages by the community networks are mesh routing protocols like OLSR, BATMAN and Babel. Moreover, our developers contribute to new hardware support and drivers, distributed network monitoring tools and efficient user interfaces for network configurations.

Common goals

  • Educate and create awareness on the subject of communication and freedom of information
  • Reduce the digital divide with DIY broadband networks
  • Unhindered distribution of knowledge and resources
  • Empower people to plan, build and operate their own networks
  • Promote and support existing and new social structures
  • Overcome the vendor-lock-in effect
  • Organize a community of many: decentralized structures are challenging in a positive way, e.g., to share information about communities, software repositories, working together efficiently but distributed

The software developed by community networks forms the basis for a wide range of solutions providing internet access. Everyone can join our community networks and can actively contribute.
