What is Bluetooth?
Bluetooth is used for short-range wireless voice and data communication. It is a Wireless Personal Area Network (WPAN) technology and is used for data communications over smaller distances. This generation changed into being invented via Ericson in 1994. It operates within the unlicensed, business, scientific, and clinical (ISM) bands from 2.4 GHz to 2.485 GHz. Bluetooth stages up to 10 meters. Depending upon the version, it presents information up to at least 1 Mbps or 3 Mbps. The spreading method that it uses is FHSS (Frequency-hopping unfold spectrum). A Bluetooth network is called a piconet and a group of interconnected piconets is called a scatternet.
