Introduction
Introduction to Bluetooth Wireless Technology
Bluetooth is a cable replacement, short- range wireless communication technology
A Bluetooth chip is
designed to replace cables by carrying the information normally carried by the cable, and transmitting it at
a special frequency to a receiver Bluetooth chip, which will then give the information received to the
cellular phones, personal digital assistants (PDA), desktop and notebooks computers, input-output devices
(mouse, keyboards, printers), and home appliances. Bluetooth refers to a worldwide standard designed to
operate in the internationally recognized ISM (Industrial Scientific and Medical) frequency band. Within
the ISM band (2.4 GHz – 2.48 GHz) Bluetooth transmissions hop between 79 separate frequencies 1,600
times every second, and with a communication range of about 10 meters.
