How Bluetooth Works

A Bluetooth® device uses radio waves instead of wires or cables to connect to a phone or computer.


A Bluetooth product, like a headset or watch, contains a tiny computer chip with a Bluetooth radio and software that makes it easy to connect. When two Bluetooth devices want to talk to each other, they need to pair.

One of the most popular applications for Bluetooth historically has been wireless audio—headsets and hands-free connectivity in cars to wireless speakers and headphones that stream music from your phone or tablet.

On 6 December 2016, Bluetooth took a massive leap forward to deliver advanced beacon and location-based capabilities in home, enterprise and industrial environments.  Bluetooth 5 quadruples the range, doubles the speed, and boosts broadcast messaging capacity by 800%—the key to enabling robust, reliable Internet of Things (IoT) connections that make full-home and building and outdoor use cases a reality.
