Our challenge was to track the location 200k people at a large festival using custom made wristbands, on a tight budget and preferably with only open source software. In this presentation we will briefly outline the overall system architecture, and subsequently focus on the software stack used to make this work. In essence, we need the versatility of cloud computing, but in a "camping-style data centre" We will show how Apache Felix, an OSGi runtime, provides the necessary mix of dynamism and efficiency to pull this off.

Tomorrowland
Tomorrowland 2014 Electronic music festival near Antwerp, Belgium 2 weekends 8 stages ~100 hectares ~100k visitors a weekend ~ 250 per ticket 11/17/14 8
Requirements
Requirements Design a wristband to do: Access control Location Profiling / feedback Crowd monitoring Integrate with 3rd party applications Something that adds to the UX 11/17/14 10
Access control Should always work Should be secure simplicity is essential: Passive RFID 11/17/14 11
Location Ability to locate individuals Ability to locate security personnel 11/17/14 12
Profiling / feedback How do the visitors behave? What acts are popular? 11/17/14 13
Crowd monitoring Find hotspots in the flow of people Dashboard for security personnel 11/17/14 14
UX UX is key Comfortable Match the festival Suitable for non-nerds 11/17/14 15
The plan
The setup Set up base stations around the terrain Wristbands will report status The base stations triangulate and consolidate the data Visualize and push the data to other applications Use regular passive RFID for access 11/17c/14ontrol 17
Something cool LED lights on the wristbands, integrated with the light show A button to send Facebook friend requests 11/17/14 18
The protocol Time slotted protocol All base stations synchronise with each other Visitor bracelets send every few minutes Staff bracelets send every few seconds 11/17/14 19
Hardware
Hardware One 3V battery for 3 days Leather Branded for the festival < $10 per bracelet 11/17/14 21
