The history of Bluetooth wireless technology
Bluetooth wireless technology is an open, accepted standard for wireless communication which means that Bluetooth electronic equipment can communicate as long as they are within approx. 10 metres of each other, making it possible to transfer data, speech, music or images without a physical connection. The mobile telephone manufacturer Ericsson invented Bluetooth
technology, naming it after the Viking King Harald Bluetooth. Just as King Harald Bluetooth united Denmark and Norway, Bluetooth technology unites various types of electronic equipment to form a coherent whole. Ericsson formed the foundation for Bluetooth as early as 1994, but the standard was not ready for use until 1998. The rst Bluetooth products came on the market in 2000.
Today, Bluetooth technology can be found in all types of electronic equipment including mobile phones, mobile headsets, PCs, keyboards, mouse devices, printers, GPS navigation units, video cameras and pocket PCs and new products are emerging every day.
Bluetooth wireless technology in practice
Today, Bluetooth technology is an essential everyday tool to be found in a variety of electronic equipment. The technology makes it easy to transfer speech between a mobile phone and a headset, a mobile phone and a pocket computer or images from a digital video camera to a PC. Even though two Bluetooth units can nd each other and be connected, because they both comply with the standard, it may
not necessarily make sense for them to speak to each other. For instance, a Bluetooth mouse would not prot much from a connection with a digital camera, or a headset with a keyboard. The basic requirement for Bluetooth units to be able to communicate is that they are located within 10 metres of each other. That is the range of the Bluetooth radio waves at least under the current standard.
As Bluetooth technology becomes more common, however, we will undoubtedly see CD players that send sound to ampliers via Bluetooth, which then transfer the sound to speakers in the same way. A Bluetooth enabled pocket computer will
automatically synchronise with a companys diary and make sure that the days e-mails are ready to be read on the screen. And car radios will turn the music down and transfer the speech from a mobile phone when it rings.

The highest security

If Bluetooth units are to communicate without others listening in, Bluetooth electronic equipment must be paired. This means that the equipment must recognise one another and be accessed with the same number/pin code. The process is simple, only needs to be carried out once and safeguards against others with Bluetooth headsets being able to hear your phone conversations or receive your data on
another pocket PC. For extra security, Bluetooth electronic equipment can hop randomly between 79 frequencies 1,600 times per second, which makes it virtually impossible for anyone to listen in. Furthermore, it is possible to encrypt the information sent between equipment units with a code that only those two units know.
It is also possible to ease security if, for instance, you wish to make it easier to exchange data or play against others with Bluetooth equipment.
The technology behind Bluetooth enabled products
Bluetooth wireless technology works in an open frequency spectrum at 2.4 gigahertz, the same as wireless networks, telephones and other electronic equipment. It is possible for all types of equipment to operate within the same spectrum without disrupting each other because a frequency consists of several channels which the equipment can hop between and, in that way,
nd channels which are quiet. With the Bluetooth 1.2 standard, electronic equipment can nd quiet channels beforehand, communicate between them and resend data if anything is lost due to noise. Todays Bluetooth signals have a strength of max. 2.5 milliwatts and a range of approx. 10 metres (Class 2 equipment). The weak signal means
that there must not be too many or large physical obstacles between the Bluetooth devices that are communicating. A key advantage of the weak signal of Bluetooth equipment is that the electromagnetic radiation emitted by all electronic equipment is very weak. In fact, the strength is approx. 1/800 of that emitted by a mobile phone.

How to connect a Bluetooth headset
The following example shows how simple it is to connect a Jabra BT250 Bluetooth headset to, for example, a Sony Ericsson T610 mobile phone with Bluetooth: Turn on Jabra BT250, but make sure the On and Volume up buttons are pushed in until the blue LED lamp is constantly lit. The headset is now in pairing mode. On the T610, select the menu item
the display shows Jabra 250 Added to My Devices. To exit all of the menus, press the Return button continuously for a moment or several times in a row. You can nd the procedures for connecting popular Bluetooth mobile
phones and Jabra headsets at www.jabra.com. Now you can enjoy the excellent comfort of your Jabra headset every day regardless of whether you use it on your left or your right ear. Furthermore, Jabra has excellent sound quality and can run for up to 8 hours on a single charge.
Connectivity, then Bluetooth, and then select Turn on and press the Select button. In the Bluetooth menu, select My devices and then Add. The telephone will now nd Jabra 250 and all you have to do is select it with Select. You are asked for a password. Key in 0000 (four zeros) and press OK. The equipment is now paired and

Bluetooth glossary

3G: Third generation of mobile telephony with high transmission speeds that allow the transfer of video, music, data, etc. to mobile electronic equipment, such as in connection with video telephony. Bluetooth: Open standard for wireless communication between electronic equipment. Bluetooth class: The standard denes several classes which indicate, among
other things, the strength of the Bluetooth units signal and which services it oers. Bluetooth services: A Bluetooth unit oers various services, for instance reproducing sound, transferring les, modem function, etc. When Bluetooth equipment is paired, information on which services are oered is exchanged. Electromagnetic radiation: All electrical and electronic units
emit greater or lesser amounts of electromagnetic radiation. A Bluetooth unit emits approx. 800 times less radiation than a mobile phone. Encryption: Scrambling of the data that is sent between Bluetooth units. Encryption is advanced and means, along with frequent changes in transmission frequency, that a Bluetooth connection is virtually impossible to tap. Frequency band: Normally, Bluetooth technology uses a frequency band at
79 MHz which is located in the 2.4 GHz spectrum. Frequency hop: See Spread-Spectrum frequency hopping. Gigahertz: Billions of cycles per second. Hands-free: Operation of a mobile phone without the use of hands, for instance, the ability to call a person simply by speaking the name of the person. Headset: A unit consisting of a head telephone and a microphone which is worn on the ear or head and which
makes it possible to speak into a (mobile) telephone without the use of hands. Headsets may be wireless, using Bluetooth technology, or connected with a wire. Interference: When two electric units send on the same frequency and disrupt each others reception. Milliwatt: A measurement of transmission eect. Bluetooth units transmit at 1 milliwatt, ensuring a range of approx. 10 metres.

Jabra MiniGel: Patented and ergonomic soft earpiece which ensures high quality sound without shutting out the world. Bluetooth adaptor: An adaptor which is attached to mobile phones that do not have Bluetooth technology, enabling the use of Jabra headsets. Pairing: Coding two Bluetooth units to communicate so they can exchange data, speech, etc. This normally involves entering the same number code of your choice into both units.
Protocol: A language between electronic units enabling them to communicate. Bluetooth is a standard protocol that all Bluetooth units understand. Radio frequency: Bluetooth wireless technology uses radio waves on the ISM frequency band, which is located at 2.45 GHz (gigahertz). Spread-Spectrum frequency hopping: With this technology, Bluetooth units hop between 79 frequencies 1,600 times per second.
Radiation: See Electromagnetic radiation. Wireless: Electronic equipment connected via radio waves without the use of wires.
