Babel Wireless Mesh hackathon (Paris, 19-20-21 July 2013)

A hackathon dedicated to the Babel wireless mesh routing protocol will be held during three days in Paris, at the hackerspace. The event primarily aims at testing the new features of Babel (diversity, RTT metric, source-specific routing, etc...) in a real-world environment.


Start: Friday 19 July @ 09:00

End: Sunday 21 July @ 22:00 


  • Setup of a testbed of 20 nodes or more, some of them on batteries
  • Test the new features of Babel in real-world conditions
  • Test interoperability between different implementations and different extensions of the protocol
  • Basic tests inspired by the Wireless Battle Mesh ones
  • Data collection, statistics and reproductibility of the experience
  • Bug hunting (hopefully there aren't many)
  • Degustation of belgian beers, and probably Attitude Adjustment cocktails too :)


Along with the main events, some talks are scheduled on Saturday and Sunday. Feel free to propose a talk, they will be listed on the wiki page of the event:

IS4CWN - Call for proposals - 2013 feiern wir den 10. Geburtstag von Freifunk!

Seit dem ersten Wireless Community Summit 2004 in Djursland "Fresh Air - Free Networks" haben sich Meshing und andere Community Technologien deutlich weiter entwickelt, sind einfacher geworden und überall auf der Welt sind freie Netzwerke gewachsen. Freifunker haben grundlegenden Anteil an dieser Entwicklung. Unsere Netzwerktechnologien eröffnen Menschen Möglichkeiten, die kommerzielle Anbieter von Kommunikationsinfrastruktur nur teuer oder gar nicht bieten bzw. mehr und mehr einschränken.

Vom 2. bis 4. Oktober findet der "International Summit for Community Wireless Networks" in Berlin statt.

Wir wollen gemeinsam technische, soziale und politische Implikationen von Wireless Community Networks diskutieren. Speziell richten wir den Fokus in diesem Jahr auf Anwendungen, Services und Contents, die innerhalb des lokalen Community Netzwerkes angeboten werden.

Unter anderem sind Vorträge, Workshops, OpenSpaces und ein Hackathon unter dem Titel "Where do we grow from here?"
Und natürlich wird auch gefeiert ...

Sendet jetzt Eure Vorschläge ein und gestaltet den Summit aktiv mit:

Spread the word und wir freuen uns auf Eure Ideen!
Viele Grüße von Monic, Jürgen und Patrick

Podcast from Battle of the mesh Aalborg with Rundfreifunk

Listen to the podcast of the Wireless Battle of the Mesh 2013 in Aalborg here or on Soundcloud.

Unboxing Routers on the Table at Battlemesh event

some from Wireless Communities worldwide met in Aalborg University to have a whole week to make test for some routing protocols, that are able to make wifi communications possible for mesh networking. these are some cuts from interviews with that people at the last night, when they were going out for party and to sum up that week.

The Battlemesh event that aims at bringing together people from across Europe to test the performance of different routing protocols for ad-hoc networks, like BabelB.A.T.M.A.N.BMXOLSR802.11s and Static Routing. It is a tournament with a social character. The goal of the WirelessBattleMesh events is to set-up hands-on testbed for each available mesh routing protocol with a standard test procedure for the different mesh networks.



Freifunk verbindet! Trefft uns auf dem Wireless Community Weekend vom 10.-12. Mai 2013 in Berlin

Philipp Seefeldt hat auf Vimeo den Animationsfilm Freifunk verbindet! veröffentlicht. Die Idee dazu kam von Sven Heinze und Juergen Neumann. Beim Text half Silke Meyer, gesprochen hat Anne Helm und die Musik wurde von Thomas Deittert geschrieben. Ihr könnt das Video gerne auf Eurer Website einbinden.

Wenn ihr mehr über Freifunk und Freifunker aus Deutschland und anderen Ländern erfahren möchtet, kommt zum Wireless Community Weekend in die c-base nach Berlin vom 10.-12. Mai. Am 8. und 9. Mai finden bereits informelle Treffen statt.
