Bluetooth is a wireless technology that allows devices to connect and exchange data over short distances without using cables. It uses radio waves to create a secure connection between devices like phones, headphones, speakers, keyboards, smartwatches, and cars.
Bluetooth works by pairing two devices together. Once paired, they can automatically reconnect when they’re near each other. It’s designed to use very little power, which is why it’s common in wireless earbuds, fitness trackers, and other battery-powered gadgets.
The typical range of Bluetooth is about 30 feet (10 meters), though newer versions can reach farther depending on the device. It’s commonly used for streaming audio, transferring small files, connecting controllers, and linking smart home devices.
