iBeacon definition

iBeacon refers to a small Bluetooth Low Energy (BLE) device introduced by Apple in 2013. It emits a signal that can be picked up by nearby iOS and Android devices equipped with Bluetooth. iBeacon is essentially a transmitter that sends out a unique identifier that can trigger actions on compatible devices within its proximity.

How does an iBeacon work?

In simple terms, an iBeacon transmits its signal to other Bluetooth-enabled devices. Once such a device comes within range, usually up to 70 meters, it detects the signal and determines its proximity based on the signal strength. Once the device detects the iBeacon, it can trigger various actions programmed into compatible apps installed on the device.

Because an app can send alerts to users when they come within range of an iBeacon, this technology can be used by various shops to send personalized promotions when a customer enters a store.

Also, iBeacon can be used in the hospitality industry to check people in and out automatically. Apps can trigger contextual automation actions, such as adjusting smart home devices' settings or launching specific app features based on users' proximity to iBeacons.
