Basics of Bluetooth technology

Bluetooth technology is a communication technology. It is used for wireless communication between devices in a small range. It not only frees us from hassles of wiring all devices but also gives us same level of security. The technology has matured into a highly robust, widely accepted and low cost medium to communicate between different types of devices. With a Bluetooth enabled phone and handset, you can talk without a wired headphone. Similarly, with a blue tooth enabled computer and printer, you can do printing jobs without a wire connection between the two devices. There are 3 broad categories of Bluetooth devices. These categories depend on the range of the device. Class 3 category has a mere range of about a meter. Class 2 category is of a medium range of about 30 feet and has found application in mobile devices. The Class 1 category devices have 10 times the range of Class 2 devices. It has many industrial applications where devices are laid at big distance from each other but still need to communicate regularly.
