Bluetooth is a proprietary open wireless technology standard for exchanging data over short distances ( using short-wavelength radio transmissions in the ISM band from 2400 – 2480 MHz ) from fixed and mobile devices, creating personal area networks ( PANs ) with high levels of security.

Bluetooth is managed by the Bluetooth Special Interest Group, which has more than 16, 000 member companies in the areas of telecommunication, computing, networking, and consumer electronics.

The word " Bluetooth " is an anglicised version of the Scandinavian Blåtand / Blåtann, the epithet of the tenth-century king Harald I of Denmark and parts of Norway who united dissonant Danish tribes into a single kingdom.

The implication is that Bluetooth does the same with communications protocols, uniting them into one universal standard.

The Bluetooth logo is a bind rune merging the Younger Futhark runes 8px ( Hagall ) ( ᚼ ) and 8px ( Bjarkan ) ( ᛒ ), Harald's initials.

The combination of these ( BR and EDR ) modes in Bluetooth radio technology is classified as a " BR / EDR radio ".

Bluetooth is a packet-based protocol with a master-slave structure.

They also demonstrated the first Bluetooth PIN and Linkkeys cracker, which is based on the research of Wool and Shaked.

Maximum power output from a Bluetooth radio is 100 mW, 2. 5 mW, and 1 mW for Class 1, Class 2, and Class 3 devices respectively, which puts Class 1 at a lower level than mobile phones, and the other two classes much lower.

The Bluetooth Innovation World Cup, a marketing initiative of the Bluetooth Special Interest Group ( SIG ), is an international competition encouraging the development of innovations for applications leveraging the Bluetooth low energy wireless technology in sports, fitness and health care products.

is: Bluetooth

The Bluetooth Special Interest Group ( SIG ) is the body that oversees the development of Bluetooth standards and the licensing of the Bluetooth technologies and trademarks to manufacturers.

Originally developed by Ericsson, Bluetooth technology is now used in many different products by many different manufacturers.

From 2002-2004 the Bluetooth SIG was based in Overland Park, Kansas USA and is now based in Kirkland, Washington.

Encryption is also used to protect data in transit, for example data being transferred via networks ( e. g. the Internet, e-commerce ), mobile telephones, wireless microphones, wireless intercom systems, Bluetooth devices and bank automatic teller machines.

Task group one is based on Bluetooth technology.

A wireless personal area network ( WPAN ) is a PAN carried over wireless network technologies such as IrDA, Bluetooth, Wireless USB, Z-Wave, ZigBee, or even Body Area Network.

A Bluetooth PAN is also called a piconet ( combination of the prefix " pico ," meaning very small or one trillionth, and network ), and is composed of up to 8 active devices in a master-slave relationship ( a very large number of devices can be connected in " parked " mode ).

Like DECT, DECT ULE standard uses the 1. 9 GHz band so suffers less interference than Zigbee, Bluetooth or Wi-Fi, which all run on 2. 4 GHz.

* Bluetooth, a wireless personal area network standard

Bluetooth is a wireless standard used to communicate between electronic devices like mobile / smart phones, headsets, navigation systems, computers etc.

Full support for AirPort ( Apple ’ s implementation of the IEEE 802. 11b-1999 wireless networking standard ), and partial support for AirPort Extreme, are also built into Yellow Dog Linux, as are support for Bluetooth and support for accessing the Internet over cellular phones.

iPod Integration and Bluetooth are now standard across the range and the popular ZF 6-speed Gearbox has also been made standard across the range, spelling the end of the 4-and 5-speed variants.

* Bluetooth hands-free interface was made standard.

) However, in the early 2000s, Bluetooth was repurposed as a device-to-computer wireless communication standard, and has succeeded well in this regard.

The 2007 Altima sports some more recent innovations in the market, including, but not limited to, a standard Smart Key ( referred to as the Nissan Intelligent Key ® with Push-Button Ignition ), Bluetooth capability for cell phones, and a parking camera.

It has a standard 3. 5 mm headphone jack, a longer lasting battery than the Tungsten E, has Bluetooth capability, and a single speaker on the back.

Some cordless phones can use the Bluetooth standard to ring and answer calls on behalf of a mobile ( cellular ) phone near the base station.

In February 2010, Chevrolet unveiled a 75th anniversary edition of the Suburban, which will have the LTZ trim with white diamond tricoat exterior paint and cashmere interior, along with standard 20-inch chrome-clad wheels, revised roof rails, integrated navigation radio, XM Satellite Radio, Bluetooth phone connectivity, rearview camera, rear park assist, remote starting, adjustable pedals, and leather upholstery with heated / cooled front seats.

The trims will also get an updated modification, with the rear audio system, Bluetooth, floor console / storage area, wood grain interior, luggage rack rails, body-color exterior door handle / mirror caps and premium-cloth front bucket seats now standard on the 1LS trim, and chrome recovery hooks, two-speed transfer case, and 20-inch chrome wheels standard on its 1LZ 4WD models.

It replaced the first generation iMac G5 and has a handful of configuration differences-more RAM, a larger hard drive, improved graphics, Gigabit Ethernet, and standard AirPort Extreme ( 802. 11g ) and Bluetooth 2. 0 + EDR.

The DTCP standard has branched out to cover a variety of media types to respond to these industry changes, and now supports USB, IP, WiFi, Bluetooth and MOST ( a media standard for automotive platforms ) in addition to FireWire.

USB and FireWire support, and support for dial-up, Ethernet, and wireless networking ( via 802. 11b and Bluetooth ) soon became standard across Apple's entire product line.

USB audio input is standard in the EX-L trim while hands-free Bluetooth connectivity is exclusive to the EX-L trim equipped with navigation system.

The phone is indeed very versatile and has a huge feature set, especially when compared to other phones of its time, although it lacks many features now considered standard for modern phones, like colour display, integrated camera, polyphonic or digitized ringtones, Bluetooth and GPRS functionality.

For the 2009 model year, all Rio and Rio5 trims received standard Sirius Satellite Radio ( complimentary for three months ) and radios with USB port & auxiliary jack, the auxiliary jack substituting for a Bluetooth mobile phone connection for devices with an earphone jack, e. g., the iPhone.

The Bluetooth communications protocol in these devices is named after this king, ostensibly due to his abilities to make diverse factions communicate with each other.
