  1. 1. Funkfeuer + community wifi networks in Europe L. Aaron Kaplan (aaron@lo-res.org) Presentation held at the Berkman Center, Cambridge March 2009
  2. 2. Open Source
  3. 3. Open Hardware
  4. 4. Open Networks
  5. 5. It [radio] is purely an apparatus for distribution, for mere sharing out. So here is a positive suggestion: change this apparatus over from distribution to communication. The radio would be the finest possible communication apparatus in public life, a vast network of pipes. Bertolt Brecht «The Radio as an Apparatus of Communication» (in Blätter des Hessischen Landestheaters, Darmstadt, No. 16, July 1932)
  6. 6. Current Internet • scale free • a lot of concentration on key nodes • getting more and more centralized
  7. 7. Contrast
  8. 8. Contrast • less scale free, more meshed or completely meshed • decentralized, anarchic • more resistant to failures? • mobile • innovation at the edge
  9. 9. Motivation • Censorship resistant networks (“3 strikes out”) • (anti-surveillance), anti data retention • Independence, running own network • financially stable, self-sustaining
  10. 10. How it started in Vienna • q/spot history • Book - asked if we can use 10 existing locations for free • Tested AODV, mobilemesh, OLSR. OLSR sort of worked. Same results in Berlin Freifunk • Public presentation, invitation to the public
  11. 11. Where are we now? • aaron@viviroof:~$ ip route show table all | wc -l 674 • 240 roofs • repeated in Graz, Bad Ischl, Weinviertel • halfway distance to Bratislava • longest links 30km • vibrant very active community • fibre co-sharing / digging
  12. 12. In parallel... • Guifi.net Barcelona • Djursland - forgotten by the telco industry • Berlin Freifunk • Athens wireless • Paris Sans Fils • czfree network
  13. 13. Principles of Funkfeuer • Free, everybody is allowed to join • Pico peering agreement. Free transit • Bandwidth provided by association • Experimental network • Value is (in) the network
  14. 14. Financial Sustainability
