Bluetooth

 

As an alternative to wired connections, Blue­tooth offers a radio-based method of linking modems, key­boards, loud­speakers – and today also hands-free phone systems in cars ... and even babies’ dummies. In 2018 this form of data transfer will already be 20 years old: Blue­tooth was developed in 1998 in order to connect equipment over short distances by radio. Today, more advanced versions of the techno­logy cover many other functions: with the help of Blue­tooth, appliances and equipment can be controlled remotely or data can be synchronised.
