What is Bluetooth, and how does it work?
Bluetooth is a wireless technology standard that allows short-range communication between devices. It operates by using radio waves in the 2.45 GHz ISM band, allowing devices like smartphones, tablets, and headphones to connect and communicate without the need for cables. Bluetooth technology relies on a master-slave relationship where one device, the master, controls the communication and can connect with multiple slave devices.
The connection process begins with one device searching for nearby Bluetooth-enabled devices. Once a device finds a potential connection, it initiates pairing, which often involves entering a PIN or confirming a prompt. Once paired, the devices can exchange data and maintain a connection as long as they remain within range, typically about 30 feet or 10 meters, depending on the device class.
What devices can I connect using Bluetooth?
Bluetooth can connect a wide range of devices including smartphones, tablets, laptops, smartwatches, wireless speakers, headphones, and smart home devices like lights and locks. In addition, Bluetooth technology is commonly used in automotive systems, allowing for hands-free calling and media streaming through car stereos.
