Bluetooth is a type of technology based on radio waves that is used all over the world. It enables two or more devices to connect wirelessly (invisibly, without cables). They generally have a range of around 30 feet. For instance, this could be your iPhone ‘talking’ to your iPad, which then ‘talks’ to your TV. ‘Talking’ in these examples could be sharing audio, videos or other types of media and data. This is called streaming. You could also use a Bluetooth connection to send an address from the contacts in your smartphone to the GPS in your car.
There are Bluetooth-enabled smartphones, TVs, computers, tablets and music systems. You probably have all or many of these devices in your home. Bluetooth comes in hearing aids too. Having a Bluetooth hearing aid might help you connect with your friends, family, colleagues, and the world in greater ways.
