Gatwick Airport installs 2,000 BLE beacons for augmented reality wayfinding

Some 2,000 Bluetooth Low Energy (BLE) beacons have been installed across London’s Gatwick Airport to provide an indoor navigation system and an augmented reality wayfinding service so that passengers can be shown directions in the camera view of their mobile device. The beacon system is also open to retailers and other third parties, allowing them to detect the proximity of consumers and send relevant offers or promotional messages to their smartphones if the passenger has chosen to receive them.
