Beacon technology involves small, wireless devices known as beacons that use Bluetooth Low Energy (BLE) to transmit signals and communicate with smartphones or other compatible devices within close proximity. These devices emit signals that can trigger location-based actions or deliver targeted content to users' mobile devices. In the retail industry, for example, beacons can be strategically placed in stores to send notifications, promotions, or personalized offers to customers' smartphones as they browse the aisles. Beacon technology has applications beyond retail, including in museums, events, and indoor navigation systems, providing a seamless and personalized user experience based on location awareness.
