Wireless technologies are bringing future to present.
Bluetooth is a one such wireless technology which is
reshaping the way we live and work. It is an implementation
of a protocol defined by the IEEE 802.15 standard. The
protocol operates in the unlicensed industrial, scientific and
medical (ISM) band at 2.4 to 2.485 GHz, using a spread
spectrum, frequency hopping, full-duplex signal at a nominal
rate of 1600 hops/sec. The 2.4 GHz ISM band is available and
unlicensed in most countries [1].
