What is Bluetooth - Definition?

Bluetooth is a wireless technology for data exchange in short distance. It uses short-wavelength UHF radio waves in the ISM band from 2.4 to 2.485 GHz. This technology was invented by Ericsson in 1994.

There are basically two important parameters in Bluetooth devices: class and supported profiles.

“Class” denoted the distance up to which connection is possible. Most of the mobile devices are of class 2. Class 2 allows communication of to 10 meters.

Profile is the type of connection. With improvements on this technology, we are seeing new Bluetooth profiles.
