README ======= 1.) Background Sputnik was a real time tracking application run at the 23c3. Attendees of the 23C3 were able to voluntarily participate in this system by purchasing an Sputnik transponder which they could carry with them during the whole event. The data gathered from the base stations during this event is made available for data mining. The Sputnik is a small active 2.4GHz RF Beacon, whose signal was picked up by one or multiple of the 20+ Sputnik base stations installed in the event venue. For details about the base station locations go to http://www.openbeacon.org/. Approximately 900 partcipants were tracked. 2.) The Data The file format is currently still binary, please see the header file openbeacon.h for details considering the format. As soon as possible, we will publish an ASCII version of the data compatible. *Important* Every new hour a new data file was created; yet, packages might be saved over file boundaries. Therefore the easiest way is to cat all log files together. The data is in network byte order. 3.) Licence The data is published under Creative Commons Attribution-Noncommercial-Share Alike 2.5 License. http://creativecommons.org/licenses/by-nc-sa/2.5/ For details about the hardware platform and other information: http://www.openbeacon.org/ contact email: Milosch Meriac
