Bluetooth is a short-range wireless technology standard that is used for exchanging data between fixed and mobile devices over short distances and building personal area networks (PANs). In the most widely used mode, transmission power is limited to 2.5 milliwatts, giving it a very short range of up to . It employs UHF radio waves in the ISM bands, from 2.402GHz to 2.48GHz. It is mainly used as an alternative to wired connections to exchange files between nearby portable devices and connect cell phones and music players with wireless headphones, wireless speakers, HIFI systems, car audio and wireless transmission between TVs and soundbars. Bluetooth is managed by the Bluetooth Special Interest Group (SIG), which has more than 35,000 member companies in the areas of telecommunication, computing, networking, and consumer electronics. The IEEE standardized Bluetooth as IEEE 802.15.1 but no longer maintains the standard. The Bluetooth SIG oversees the development of the specifi ...

Bluetooth Special Interest Group
The Bluetooth Special Interest Group (Bluetooth SIG) is the standards organization that oversees the development of Bluetooth standardization, standards and the licensing of the Bluetooth technologies and trademarks to manufacturers. The SIG is a not-for-profit, non-stock corporation founded in September 1998. The SIG is headquartered in Kirkland, Washington, Kirkland, Washington (state), Washington, US. The SIG does not make, manufacture or sell Bluetooth-enabled products. Introduction ''Bluetooth'' technology provides a way to exchange information between wireless devices such as Personal digital assistant, PDAs, laptops, computers, Computer printer, printers and digital cameras via a secure, low-cost, globally available short-range radio frequency band. Originally developed by Ericsson, ''Bluetooth'' technology is now used in many different products by many different Manufacturing, manufacturers. These manufacturers must be either Associate or Promoter members of (see belo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wireless Speakers
Wireless speakers are loudspeakers that receive audio signals using radio frequency (RF) waves rather than over audio cables. The two most popular RF frequencies that support audio transmission to wireless loudspeakers include a variation of WiFi IEEE 802.11, while others depend on Bluetooth to transmit audio data to the receiving speaker. Apart from the employed RF standard, such speakers can basically be distinguished by their dedicated field of use. Portable wireless speakers for outdoor use are typically designed for ruggedness, portability and battery life, whereas stationary wireless speakers with a focus on good sound quality are meant to be used in home audio systems or surround sound systems for TV or video. Further, types for special applications like waterproof speakers for use in the shower or speakers for a Voice user interface, voice assistant may intermix between the properties of the two former. Overview Wireless speakers are composed of two units: a main speake ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jelling Stones
The Jelling stones () are massive carved runestones from the 10th century, found at the town of Jelling in Denmark. The older of the two Jelling stones was raised by King Gorm the Old in memory of his wife Thyra. The larger of the two stones was raised by King Gorm's son, Harald Bluetooth, in memory of his parents, celebrating his conquest of Denmark and Norway, and his conversion of the Danes to Christianity. The runic inscriptions on these stones are considered the best known in Denmark. In 1994, the stones, in addition to the burial mounds and small church nearby, were inscribed on the UNESCO World Heritage List as an unparalleled example of both pagan and Christian Nordic culture. Significance The stones are strongly identified with the creation of Denmark as a nation state. Both inscriptions mention the name "Danmark" (in the form of accusative "tanmaurk" () on the large stone, and genitive "tanmarkar" (pronounced ) on the small stone). The larger stone explicitl ...

Harald Bluetooth
Harald "Bluetooth" Gormsson (; , died c. 985/86) was a king of Denmark and Norway. The son of King Gorm the Old and Thyra Dannebod, Harald ruled as king of Denmark from c. 958 – c. 986, introduced Christianization of Denmark, Christianity to Denmark and consolidated his rule over most of Jutland and Zealand. Harald's rule as king of Norway following the assassination of King Harald II of Norway, Harald Greycloak of Norway was more tenuous, most likely lasting for no more than a few years in the 970s. Some sources say his son Sweyn Forkbeard forcibly deposed him from his Danish throne before his death. Name Harald's name is written as runic ''haraltr : kunukʀ'' (ᚼᛅᚱᛅᛚᛏᚱ ᛬ ᚴᚢᚾᚢᚴᛦ) in the Jelling stone inscription. In normalized Old Norse, this would correspond to ''Haraldr konungr'', i.e. "Harald Germanic king, king". The Latinized name as given in the medieval Danish chronicles is ''Haraldus Gormonis filius'' (Harald, Gorm's son). The given name ...

The Long Ships
''The Long Ships'' or ''Red Orm'' (original Swedish: ''Röde Orm'' meaning ''Red Orm'', lit. ''Red Serpent'' or ''Red Snake'') is an adventure novel by the Swedish writer Frans G. Bengtsson. The narrative is set in the late 10th century and follows the adventures of the Viking Röde Orm - called "Red" for his hair and his temper, a native of Scania. The book portrays the political situation of Europe in the later Viking Age, Andalusia under Almansur, Denmark under Harald Bluetooth, followed by the struggle between Eric the Victorious and Sven Forkbeard, Ireland under Brian Boru, England under Ethelred the Unready, and the Battle of Maldon, and then the Byzantine Empire and its Varangian Guard, Kievan Rus and its neighbors the Patzinaks - all before the backdrop of the gradual Christianization of Scandinavia, contrasting the pragmatic Norse pagan outlook with the exclusiveness of Islam and Christianity.
