freifunk at the CeBIT 2012

The CeBIT and Linux New Media are sponsoring Free/Open Source Projects to join the CeBIT from March 6-10 in Hannover, Germany. Freifunk was accepted as an Open Source organization. We have a booth and already have a confirmation of some Italien friends from the Ninux community who will join as well. 

I have set up a Wiki page for everyone who would like to help with the organization.

Preparations and communications are running over the following channel:

The organizers already confirmed to us, that we will have power supply and Internet. "Connectivity will be by network cable, not by WiFi." I think we can take care of that.

Wireless Battle Mesh v5 in Greece - Call for papers

Wireless Battle Mesh v5 is at hand and it is time to bring together the agenda. As last year's attempts to construct an agenda was well received and provided the grounds for numerous healthy discussions the broad majority asked for similar action. However, the number of talks is going to be reduced to leave more time for individual discussions and testing.



To allow an efficient handling of your submission, please provide the following information and send them to me directly in form of an email:

* your name

* the type of your slot (talk/workshop/panel discussion/lightening talk)

* your topic headline

* your topic description which can brief (does not need to exceed a couple of lines) but should provide a reasonable summary of your talk

* the dates of your stay at the event + (optional) preferred day for your slot

* length of the slot if you wish to do a workshop (all other slots will be limited to one hour - notify me in advance if you think that is not enough for you)

Feel free to contact me with your ideas in case you are unsure about your topic. Last year's agenda also should be able to provide some insights:



Submissions are accepted until and including the 16th of March. Everyone missing this deadline still has the opportunity to apply for a lightening talk slot. These slots can be acquired by simply contacting me during the event. The list of registered lightening talks will be published in the battlemesh wiki.

The final program will be made available in the aforementioned wiki during the second week of March.

GSoC 2011: Videochat for Diaspora with Vittorio

I’m writing about the results achieved with my Google Summer of Code project, for the Ninux community, under the umbrella of Freifunk (I thank them both for the opportunity they gave me).Briefly it consisted in developing a video chat feature for Diaspora*, a distributed social network.This project has received a very big feedback and appreciations from the entire Diaspora community, including the core team, who helped and supported me during the development.Basically, it provides two new functionalities to the Diaspora engine:

  • Textual chat, based on XMPP signaling protocol
  • Video chat, using Jingle XEP

Both have been developed in Javascript, with some Rails code. It usesStrophe.js library for the textual chat, based on XMPP Over BOSH standard, and a self-made extension of it to realize Jingleprotocol.The project includes a custom ejabberd module in Erlang for the integration of ejabberd/diaspora databases, an Actionscript part for the video chat stuff and an external authentication script written in Ruby used by ejabberd to authenticate users from Diaspora.The project has been split in two pull requests, and we’re currently fixing them before merge with master repository: [1],  [2].Source code can be found at, under “jabber” and “video_chat” branches.Setup instructions here. Some screen-shots: [1], [2], [3].I hope it will be soon merged and improved by me and the community, to make it available on every Diaspora* pod!Vittorio**This article appeared first on the website of Ninux, our friends from Italy:

Hardware BasarMany wifi activists has lockers and shelfs full of wifi equipment, boards, enclosures, wifi cards, antennas, cables and pigtails. A lot of wifi stuff just sits there and wait to be used or just gets dusty. If this equipment still works and can be used better, lets re-use it and share it to the wifi community.So bring it with you to the wireless community weekend and gift it to a big live moderation stage auction. All parts starts at one euro, the collected money goes back to the community as a donation to give a financial support the wireless community weekend event.

Wireless Battle of the Mesh V3 - June 2-6, 2010 in Bracciano, Italy

The next 'Wireless Battle of the Mesh' will take place from Wed 2nd till Sun 6th of June in Bracciano (near Rome), Italy. The event aims to bring together people from across Europe to test the performance of different routing protocols for ad-hoc networks, like Babel, B.A.T.M.A.N., and OLSR. This third WBM will be improving the testbed conditions for mesh protocols with standardized testing procedures that will be reported after the event for the wireless communities.

On the development side, a flashing tool will be presented to simplify the deployment of such wireless networks based on OpenWrt stable release and packages for each protocol.

If you are a mesh networking enthusiast, community networking activist, or have an interest in mesh networks you have to check this out!

Informations about the event are gathered at:

The Wireless Battle of the Mesh is an event that aims at bringing together people from across Europe to test the performance of different routing protocols for ad-hoc networks, like Babel, B.A.T.M.A.N., OLSR, and Static Routing. It is a tournament with a social character. If you are a mesh networking enthusiast, community networking activist, or have an interest in mesh networks you might want to check this out! 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. During the different WBM events, similar hardware and software configuration will be used based on the OpenWRT BoardSupportPackage and packages for each protocol implementation. The WBM events are also a great opportunity to develop testing tools for PHY/MAC radio layers (drivers, scripts and PHY analyzers). 

Google Summer of Code: The event will also offer opportunities for students and mentors participating in Freifunk Google Summer of Code to meet up and work on projects.
The "tournament" will take place from June 2-6, 2010.

The event will take place in the camping Porticciolo in Bracciano, Italy. along the border of the lake of Bracciano, just North-West of Rome.

Registrations will be available at different hackerspaces (Fusolab, HSBXL, /tmp/lab, metalab, CCC, ...) and on the official website for the event at

Every participant needs to donate 50 EUR (this should cover the costs for the camping, and the infrastructure). To finance this event, we ask you to pay when subscribing (paypal, bank transfer or cash).
