The Rise of Bluetooth Low Energy (BLE) Beacon Technology for Indoor Positioning and Context-Aware Applications
Bluetooth Low Energy (BLE) Beacon Bluetooth Low Energy, also known as Bluetooth Smart or BLE, is a wireless personal area network technology aimed at novel applications requiring lower power usage. Originally developed as a part of the Bluetooth 4.0 specification, BLE enables devices to exchange data over short distances while using significantly less power than classic Bluetooth technologies. At the core of Bluetooth Low Energy (BLE) Beacon are small, low-cost transmitters called beacons that can communicate with nearby Bluetooth-enabled devices. Beacons broadcast messages containing a universally unique identifier (UUID) and other device-specific information using Bluetooth advertising. Nearby devices with a Bluetooth radio can detect these broadcast signals to determine presence and proximity to the transmitting beacon. Beacon Form Factors and Transmission Technologies BLE beacons come in a variety of form factors depending on their intended use case. Common beacon form factors...
