A beacon is a Bluetooth Low Energy (BLE) emitter device that emits radio waves reaching several hundreds of meters and sending information to other bluetooth devices such as smartphones, computers, tablets, and more. Beacons are advantageous for many reasons, but perhaps none greater than their low energy consumption, which allows them to operate for up to twenty years. Apple was at the forefront of the beacon market when they released the iBeacon in 2013 to developers and wireless beacon manufacturers. However, the iBeacon is not a device but rather a frame format allowing bluetooth beacons to communicate with iOS devices. Today, beacons are more popular than ever, with more than 50 BLE manufacturers and countless technical platform providers. In this blog, we will discuss how beacons operate and their uses throughout various industries.
