Freifunk (Bahasa Jerman untuk Free Radio) adalah sebuah inisiatif untuk mendukung pengembangan tools untuk jaringan free mesh. Di samping itu, inisiatif ini mendukung komunitas untuk mengembangkan pengetahuan untuk mensetup jaringan mereka sendiri.

Komunitas Freifunk adalah bagian dari proyek pengembangan tool jaringan mesh termasuk Freifunk Firmware dan OpenWrt projects, protocol routing seperti OLSR dan 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. FREIFUNK Firmware/OPENWRT

The Freifunk Firmware is a modified version of OpenWrt Linux Version that is developed for router devices. The main aim of the firmware is to make it easier and faster to set up wireless mesh networks. Designed as an embedded Linux for low powered network devices the system can be adapted for a wide variety of devices. Freifunk/OpenWrt supports ad-hoc WLAN communication and layer 2 and 3 routing. Open Source routing protocols can be installed via package updates. Most common protocols are the OLSR protocol and the BATMAN routing protocol. By building the Freifunk embedded firmware together with the OpenWrt team the community is developing an easy to use self-configuring, self-fixing and self-tuning mesh network (http://wiki.openwrt.org/Freifunk). Features of the freifunk Firmware

The Freifunk firmware allows anyone to relatively easily build mesh networks of routers. Such networks can be surprisingly scalable involving hundreds / thousands of nodes and made using normal off the shelf routers. Firmware PLUGINS

Current test version on SVN (https://dev.openwrt.org/wiki/GetSource) are enabling developers to create plugins for the firmware. These plugins will enable users to offer locations based services, local search, router CMS, local fm radio distribution via routers, and many more. An example for locations based services is Apple Bonjour that offers users to share their music in local wifi networks, however, in Freifunk mesh networks, there are many more ways to share and communicate as services are build on open standards and open source software. LOCAL SERVICES in Mesh Networks

Another project where we are connecting services is the Villagetelco project, where we adapt the firmware to offer telephone services over an adhoc network (www.villagetelco.org). ADAPTING THE FIRMWARE

Going in another direction the community also engages to port applications and desktop environments such as LXDE to OpenWrt for Freifunk clouds to offer faster devices with an X interface and making use of thousands of available applications. The porting of code from Google Android also aims to support the adaptability of the Firmware for special use cases. Communities around the world
