The document describes a large beacon implementation at the 2015 SAIL Amsterdam event. Over 2.3 million visitors experienced beacons deployed across 5 private and public networks, including long-range beacons on ships. Key stats on beacon interactions and mobile app usage are provided. The implementation helped analyze visitor behavior, follow routes, and understand one-time vs multi-day visits. Future applications discussed include using beacons for personalized digital screens in supermarkets.
