Bluetooth Beacons
Bluetooth Beacons are small, low-power wireless devices that broadcast signals using Bluetooth Low Energy (BLE) to nearby smartphones or other devices. They enable proximity-based interactions by transmitting unique identifiers, allowing apps to detect location, trigger actions, or deliver contextual information without requiring a direct connection. This technology is widely used for indoor navigation, asset tracking, and personalized marketing in retail, museums, and smart buildings.
Developers should learn Bluetooth Beacons when building location-aware applications, IoT solutions, or proximity-based services that require low-energy, cost-effective indoor positioning. Use cases include creating interactive museum guides, implementing contactless check-ins at events, optimizing warehouse inventory management, and enhancing retail experiences with targeted promotions based on customer proximity to products. It's particularly valuable in environments where GPS is unreliable, such as indoors.
