Bluetooth Introduction
Bluetooth is a global wireless standard for enabling short-range wireless
connections. It is a simple and instant radio solution that allows different
devices to talk to one another. Bluetooth eliminates the need for
cables/wires/cords between devices such as mobile phones and headphones.
Bluetooth facilitates fast and secure transmissions of both voice and data
between devices even if they are not in line-of-sight. Most Bluetooth devices
are described as 'Class 2'. These are very low power and have a range of
about 10 meters. Some devices are Class 1. These have range comparable to
that of Wi-Fi and have a range up to 100 meters.
A limited, but growing number of devices use Bluetooth at present. Devices
