What is Bluetooth and how does it work?

Bluetooth is a way for your devices to talk to each other wirelessly over a short distance — like headphones connecting to your phone, or a keyboard connecting to your computer. It's built into most modern devices and works automatically once you pair them the first time. Think of it as creating an invisible radio connection between devices so they don't need cables.

Bluetooth is a wireless technology that lets devices communicate with each other without cables. It works by sending radio signals between devices that are close to each other — about 30 feet in most cases. Once you pair two devices for the first time, they remember each other and connect automatically whenever you turn Bluetooth on. Bluetooth is designed for short-distance, low-power communication, which is why it works for headphones, speakers, watches, and fitness trackers.
