Although Bluetooth technology has been around for a while, I am curious about the long-term usefulness and practicality in the computer and technology fields. In a December 1999 article, Heidi Monson described Bluetooth as “ An eighteen wheeler screaming down the pike, carrying the future of computing with it.” I have personally heard opinions from great excitement to general disgust for this technology. In this paper I will attempt to map its history, explain the concept, and describe its usefulness and limitations.
The first question for many people is ‘What is Bluetooth?’ Bluetooth technology is named after Harold II “Bluetooth”; a Danish King that was famous for his traveling exploits and peacefully unifying Denmark and Norway. Bluetooth technology strives to incorporate these qualities into its product by making this technology globally compatible and it also has the ability to allow several different electronic devices to communicate effectively. Bluetooth technology was developed in 1994 by L. M. Erricson Telephone to integrate its phones with all Internet enabled devices. In order to have a device Bluetooth certified, to must
Bluetooth utilizes a 9mm x 9mm microchip, which functions as a radio link. It operates in the unrestricted, globally available 2.45GHz Industry Scientific and Medical (ISM) bandwidth with a range from 10cm to 10 meters; thus eliminating the line of sight restrictions of infrared devices. A planned version would increase the range up to 100 meters. Power consumption is 0.3mA in standby mode and a maximum of 30mA while transferring data. Data transfer speeds are between 720 Kbps and 1Mbps. High performance in noisy RF environments is accomplished by transferring data using fast frequency hopping (1600 hops/sec), packet-switched protocol. Blue tooth devices connect with one another by creating an improvised Bluetooth network called a piconet. A piconet consists of a master and up to seven slaves. Security is accomplished by data encryption and channel hopping. This provides a great degree security while transferring data and ensures that devices that are not part of the piconet cannot eavesdrop on a Bluetooth connection.
The Bluetooth standard has enabled communications and computer devices to connect wireless. Although the widespread use of Blueto
