From Conception to Retirement: a Lifetime Story of a 3-Year-Old Wireless Beacon System
summary
Three-year city-scale deployment of customized BLE beacons (pilot 8 months, operation 28 months) places a device at each merchant to infer arrival/departure and influence dispatching; it serves 12,109 merchants, interacts with 109,378 couriers, and helped schedule 64 million orders worth $600M. Commodity beacons detect ~98% in pilot but field reliability averages ~75% and breaks even after ~12 months; many devices die near two years while 40% outlive shop closures. Lessons: hardware fails sooner than expected, hybrid BLE/GPS/manual systems improve coverage, and aBeacon+ replaces some hardware by using merchant/courier phones.
