Bluetooth is a wireless communication technology that allows data transmission between devices over short distances, typically up to 10 meters, although it can extend further in certain versions. It uses low-power radio waves to connect and transfer data between cell phones, headsets, computers, speakers and other compatible devices.
Having Bluetooth on a TV today is an almost essential feature, it will allow you to connect wireless headphones to watch TV late at night or for people with hearing problems, you can also connect wireless speakers or sound bars.
It also allows you to use remote controls with Bluetooth technology that can be used without pointing directly at the TV as well as wireless keyboards and mice to surf the Internet or use applications.
And one of the most innovative functions is to connect a video game controller, such as the controller of a PS4 or XBOX to play in the cloud directly from the TV without the need for a game console.
