Bluetooth

maker

Bluetooth is a wireless communication protocol for short-range data exchange.

expanded

Bluetooth is a standard for wirelessly exchanging data over short distances, typically less than 10 meters (approximately 33 feet), using 2.4 GHz ISM band radio waves. It is widely used for creating Personal Area Networks (PANs) and facilitating communications between a variety of devices such as smartphones, computers, and IoT devices, enhancing their utility by enabling cable-free interaction.

examples

Bluetooth Low Energy (BLE) in fitness trackers such as the Fitbit Inspire 3 enables device synchronization with smartphones up to a range of 10 meters.

Commonly used in wearable technology to track fitness activities and health metrics.

Bluetooth is used in wireless audio systems and headphones, such as the Sony WH-1000XM5, to facilitate audio streaming from compatible devices up to 10 meters away.

Frequently utilized in consumer audio products to allow for wireless listening experiences without proximity constraints between devices.
