Bluetooth Low Energy

Bluetooth Low Energy (BLE) is a wireless communication mode designed for short-range, low-power data exchange. It supports brief connections and periodic broadcasts for battery-powered devices.

BLE Advertising: A BLE procedure in which devices broadcast packets that nearby devices can receive without a connection. Advertising lets sensors announce data or availability while avoiding the energy cost of maintaining a connection.
Bluetooth: A family of wireless standards for exchanging data over short distances in the 2.4 GHz band. BLE is one mode within the broader Bluetooth standard family.
Bluetooth Beacon: A device that periodically broadcasts BLE packets to identify its presence or provide nearby information. Beacons use BLE advertising to broadcast identifiers without maintaining device connections.
Bluetooth Classic: The original Bluetooth radio mode, designed for continuous connections and higher data rates than BLE. Classic Bluetooth suits sustained streams better, while BLE favors intermittent low-energy exchanges.
Bluetooth SIG: The standards organization that develops and maintains Bluetooth specifications and manages Bluetooth trademarks. The SIG standardized BLE and continues to maintain its specifications.
Bluetooth Low Energy Connection: A BLE link in which two devices exchange data through scheduled radio events. Connected devices use timed events to exchange data and manage radio duty cycles.
2.4 GHz Radio Band: An unlicensed radio-frequency range used by Wi-Fi, Bluetooth, and other wireless systems. BLE shares this crowded band and must coexist with nearby transmitters.
Bluetooth Low Energy Audio: A Bluetooth audio system using the LE radio and the LC3 codec for efficient audio delivery. LE Audio extends BLE technology to synchronized audio streams and hearing devices.
Wi-Fi: A family of wireless networking standards designed primarily for local-area network access and high data throughput. Wi-Fi generally offers greater throughput but usually demands more power than BLE.
Bluetooth 4.0: The 2010 Bluetooth specification release that introduced Bluetooth Low Energy alongside Bluetooth Classic. Bluetooth 4.0 marked BLE's introduction into the core Bluetooth specification.
