ABSTRACT

Wireless communication revolutionalized the entire world. Bluetooth is one of the newest technologies whose main strength is its ability to simultaneously handle both data and voice transmissions.
Bluetooth is a new technology and standard, launched in 1998. It is essentially, a small microchip, which uses a short-range radio link to exchange information, enabling wireless connectivity between mobile phones, mobile PCs and other peripherals. When two Bluetooth enabled products come within 10 meters of each other, they will automatically connect and synchronize. Because the technology uses a short-range radio link, it means that line of sight is not required for it to function.
Bluetooth wireless technology eliminates the need for numerous wired connections to other devices. Connections are instant and are maintained even if the devices do not have a clear line of sight. The range of each Bluetooth enabled device is around 10 meters but optionally reaches distances of up to 100 meters with an amplifier.
Bluetooth also uses a short packet length, which is another benefit. This technology is suited for low-power, low-cost radio implementations and is used in some wireless LAN products.
Software has developed something called ProximityMail which uses Bluetooth to create a spontaneous "Relay Area Network" (RAN) in which users can exchange text messages via PDA’s without the e-mail addresses of mobile phone numbers within ad-hoc networks. Using this new technology, it will soon be possible to send a print command from your computer to the printer in the next room, via radio link directly through the wall!


Bluetooth is a wireless technology standard for short-distance data exchange (using short wavelength UHF radio waves in the ISM band from 2.4 to 2.485 GHz) of fixed and mobile devices and the construction of personal area networks. Invented by telecommunications provider Ericsson in 1994, it was originally conceived as a wireless alternative to RS-232 data cables.

Bluetooth is managed by the Bluetooth Special Interest Group (SIG), which has more than 30,000 member companies in the areas of telecommunications, computing, networks and consumer electronics. The IEEE Bluetooth standard as IEEE 802.15.1, but no longer maintains the standard. The Bluetooth SIG monitors the development of the specification, manages the qualification program and protects trademarks. A manufacturer must meet Bluetooth SIG standards to market as a Bluetooth device. A patent network applies to technology, which are authorized for individual qualification devices.

Nils Rydbeck, CTO of Ericsson Mobile in Lund, Sweden, and Johan Ullman, started the development of "short link" radio technology, later called Bluetooth. The aim was to develop wireless hearing aids, according to two inventions by Johan Ullman, SE 8902098-6, published 1989-06-12 and SE 9202239, published on 1992-07-24. Nils Rydbeck commissioned Tord Wingren with specification and Jaap Haartsen and Sven Mattisson with development. Both worked for Ericsson in Lund. The specification is based on frequency hopping spread spectrum technology.
