A specification for the short-range, wireless linking of devices such as PDAs, computers, and mobile phones. Bluetooth chips are inexpensive and draw little power, making them ideal for mobile devices. Bluetooth uses the unregulated 2.45 GHz band and will allow transmission speeds of up to 2.1 Mbps, though most current devices communicate at a maximum of around 1 Mbps. Frequency-hopping is used to minimize interference from other devices. Bluetooth is not designed for networking applications, and does not compete with 802.11-family products. Back
A technology specification for linking portable computers, personal digital assistants (PDAs), and mobile phones for short-range transmission of voice and data across a global radio frequency band without the need for cables or wires. Bluetooth is a frequency hopping technology in the 2.4GHz frequency spectrum, with a range of 30 feet.
A technology designed for short-range, wireless communications among computing devices and mobile products, including PCs and laptop computers, personal digital assistants, printers, and mobile phones. Designed as a cable-replacement, Bluetooth enables short-range transmission of voice and data in the 2.4 GHz frequency spectrum within a range of about 30 feet. (See WPAN). close
