OpenBeacon at the Jewish Museum Berlin

In cooperation with EMIKA, a research group from FHTW - University of Applied Science, OpenBeacon has been successfully put into operation at the Jewish Museum in Berlin. It provides localization information for a new mobile museum information system that is currently under development. Realization, practical experiences and first conclusions with OpenBeacon were presented at the Congress for Wireless Communication Information (WCI - inka.fhtw-berlin.de/wci/en/) in Berlin from Dr. Mohnke (EMIKA): www.openbeacon.org/dl/Mohnke_LokalisierungstechnikenMuseum.pdf.

CCC-Sputnik at the Chaos Communication Camp 2007

The OpenBeacon project has been presented at the Chaos Communication Camp in Finowfurt near Berlin. Milosch Meriac talked about how to use the the OpenBeacon tag "CCC-Sputnik" after the camp for all kinds of uses - as wireless keyboard sniffers, remote controls, door security systems, for art performances, intelligence applications and Smart Dust meshing systems.

His talk provides a deep insight into OpenBeacon and Sputnik hardware, firmware and protocols of used. The presentation papers are available at

OpenBeacon talk at Datenspuren in Dresden

The CCC in Dresden invited us to their annually held congress about digital privacy datenspuren.de in Dresden, Germany. Our (german) presentation papers are available at www.openbeacon.org/dl/OpenBeacon/datenspuren.pdf .

OpenBeacon aggregator software v0.6 released

We released the aggregator Software used for gathering, logging and decrypting the packets from the various readers www.openbeacon.org/dl/23C3/aggregator-0.6.tar.bz2 . Make sure that you use the same shared keys on both the aggregator and the tags.

Binary log files dropped tag ID's

It turned out that the aggregator software had a bug in the binary log code. This resulted in dropping the tag ID. Alternatively we released the XML log files at

XML observer stream log file:

First graphical analysis of Sputnik log files

Peter Meerwald has released really cool plots based on the raw sputnik data on pmeerw.net/23C3_Sputnik/ . The released plots show a interesting insight into user fluctuations during the congress and ranges of the installed readers. On his website you can also find a tool to convert the log files into a textual representation.

Heavy data mining ahead

Enjoy the collected tracking data of 23C3 -

Please data mine the data and tell us about your findings. The floorplan and the coordinates of the readers can be found below.

Raumzeit visualisation first time up !

We got finally our 3D visualization for the tag positions running !

Reader Floorplan released

We released a really nice florplan which allows you to get an idea about how the readers are distributed in the BCC building. The red number pairs indicate the last two numbers of the reader IP address (10.254.x.x). You can use that informtion to grep for an appearance of a person in a particular room - just connect to sputnik.congress.ccc.de:8000 with netcat, do a "GET /0 HTTP/1.1" and filter the result with grep.
