| Introduction to Bluetooth Wireless Technology |
| Bluetooth is a short range wireless communication technology. It allows wireless connections between Bluetooth devices such as cellular phone, personal digital assistant (PDA), desktop and notebook computer, input-output devices (mouse, keyboard, or printer), 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 (2.4Ghz – 2.48Ghz) Bluetooth transmissions hop between 79 separate frequencies 1,600 times every second, and with a communication range of about 10 meters (class II) ~ 100meters (class I). |
