iBeacon is a location-based technology that uses Bluetooth Low Energy (BLE) to broadcast signals to nearby devices. iBeacon developers create apps that can take advantage of these signals to provide contextual information and content to users based on their current location. For example, an iBeacon-enabled retail store app could display special offers and product information as a user walks through the store, or a museum app could provide audio tours and exhibit information as a user moves through the museum.
