For the medieval king of Denmark, see Harald Bluetooth. Bluetooth is a wireless technology standard for exchanging data over short distances using short wavelength UHFradio waves in the ISM band from 2. GHz3 from fixed and mobile devices, and building personal area networks PANs. Invented by telecom vendor Ericsson in 1. RS 2. 32 data cables. Bluetooth is managed by the Bluetooth Special Interest Group SIG, which has more than 3. The IEEE standardized Bluetooth as IEEE 8. The Bluetooth SIG oversees development of the specification, manages the qualification program, and protects the trademarks. A manufacturer must meet Bluetooth SIG standards to market it as a Bluetooth device. A network of patents apply to the technology, which are licensed to individual qualifying devices. The development of the short link radio technology, later named Bluetooth, was initiated in 1. Nils Rydbeck, CTO at Ericsson Mobile in Lund, Sweden, and by Johan Ullman.

The specification is based on frequency hopping spread spectrum technology. Name and logoeditEtymology of the nameeditThe name Bluetooth is an Anglicised version of the Scandinavian BltandBltann Old Norsebltnn, the epithet of the tenth century king Harald Bluetooth who united dissonant Danish tribes into a single kingdom and, according to legend, also introduced Christianity. The idea of this name was proposed in 1. Jim Kardach of Intel who developed a system that would allow mobile phones to communicate with computers. At the time of this proposal he was reading Frans G. Bengtssons historical novel The Long Ships about Vikings and King Harald Bluetooth. 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 Futharkrunes Hagall and  Bjarkan, Haralds initials. ImplementationeditBluetooth operates at frequencies between 2. MHz, or 2. 40. 0 and 2. MHz including guard bands 2 MHz wide at the bottom end and 3. MHz wide at the top. This is in the globally unlicensed but not unregulated industrial, scientific and medical ISM 2. A2dp Driver For Windows 7 64 Bit' title='A2dp Driver For Windows 7 64 Bit' />GHz short range radio frequency band. Bluetooth uses a radio technology called frequency hopping spread spectrum. Bluetooth divides transmitted data into packets, and transmits each packet on one of 7. Bluetooth channels. Each channel has a bandwidth of 1 MHz. It usually performs 8. Adaptive Frequency Hopping AFH enabled. Bluetooth low energy uses 2 MHz spacing, which accommodates 4. Originally, Gaussian frequency shift keying GFSK modulation was the only modulation scheme available. Since the introduction of Bluetooth 2. EDR, 4 DQPSK differential quadrature phase shift keying and 8. DPSK modulation may also be used between compatible devices. Devices functioning with GFSK are said to be operating in basic rate BR mode where an instantaneous bit rate of 1 Mbits is possible. The term Enhanced Data Rate EDR is used to describe 4 DPSK and 8. DPSK schemes, each giving 2 and 3 Mbits respectively. The combination of these BR and EDR modes in Bluetooth radio technology is classified as a BREDR radio. Bluetooth is a packet based protocol with a masterslave architecture. One master may communicate with up to seven slaves in a piconet. All devices share the masters clock. Packet exchange is based on the basic clock, defined by the master, which ticks at 3. Two clock ticks make up a slot of 6. In the simple case of single slot packets the master transmits in even slots and receives in odd slots. The slave, conversely, receives in even slots and transmits in odd slots. Packets may be 1, 3 or 5 slots long, but in all cases the masters transmission begins in even slots and the slaves in odd slots. The above is valid for classic BT. Bluetooth Low Energy, introduced in the 4. Bluetooth low energyRadio interface. Communication and connectioneditA master BREDR Bluetooth device can communicate with a maximum of seven devices in a piconet an ad hoc computer network using Bluetooth technology, though not all devices reach this maximum. The devices can switch roles, by agreement, and the slave can become the master for example, a headset initiating a connection to a phone necessarily begins as masteras initiator of the connectionbut may subsequently operate as slave. The Bluetooth Core Specification provides for the connection of two or more piconets to form a scatternet, in which certain devices simultaneously play the master role in one piconet and the slave role in another. At any given time, data can be transferred between the master and one other device except for the little used broadcast mode. The master chooses which slave device to address typically, it switches rapidly from one device to another in a round robin fashion. Since it is the master that chooses which slave to address, whereas a slave is in theory supposed to listen in each receive slot, being a master is a lighter burden than being a slave. Being a master of seven slaves is possible being a slave of more than one master is possible. The specification is vague as to required behavior in scatternets. Class. Max. permitted power.

Bluetooth is a standard wire replacement communications protocol primarily designed for low power consumption, with a short range based on low cost transceivermicrochips in each device. Because the devices use a radio broadcast communications system, they do not have to be in visual line of sight of each other however, a quasi optical wireless path must be viable. Range is power class dependent, but effective ranges vary in practice. See the table on the right. Officially Class 3 radios have a range of up to 1 metre 3 ft, Class 2, most commonly found in mobile devices, 1. Class 1, primarily for industrial use cases,1. Bluetooth Marketing qualifies that Class 1 range is in most cases 2. Class 2 range 51. The effective range varies depending on propagation conditions, material coverage, production sample variations, antenna configurations and battery conditions. Most Bluetooth applications are for indoor conditions, where attenuation of walls and signal fading due to signal reflections make the range far lower than specified line of sight ranges of the Bluetooth products. Most Bluetooth applications are battery powered Class 2 devices, with little difference in range whether the other end of the link is a Class 1 or Class 2 device as the lower powered device tends to set the range limit. In some cases the effective range of the data link can be extended when a Class 2 device is connecting to a Class 1 transceiver with both higher sensitivity and transmission power than a typical Class 2 device. Mostly, however, the Class 1 devices have a similar sensitivity to Class 2 devices. Connecting two Class 1 devices with both high sensitivity and high power can allow ranges far in excess of the typical 1. Some such devices allow open field ranges of up to 1 km and beyond between two similar devices without exceeding legal emission limits. YVC 1. 00. 0 USB Conference Speakerphone.
