dcterms.abstractWith the advances in wireless technology and VLSI development, consumer products from cellular phone, PC's, laptop, personal digital assistance (PDA), to audio players and digital camcorders penetrate the global market at remarkable rates by the continuous size and price reduction. There is an increasing demand to get rid of the cumbersome and proprietary cables and peripherals using nowadays for transferring information between these devices. The flexibility of connectivity also becoming an enabling factor for the convergence of computing and telecommunications, driven by the rapid growth and widespread adoption of wireless data services. It may extend to ultimately infinite applications such as in an office environment when PC's or printers link to a LAN without a fixed Ethernet port, or when Fax machines get connected to the public network at homes. In response to all these new market challenges, Bluetooth is suggested to be an answer. Bluetooth technology is created to replace cables used to connect different mobile devices with radio frequency waves. The technology encompasses a very small, low-cost, low power and light-weight radio that easily form ad-hoc, secure links between various devices to allow personal connectivity. It creates many useful mobile usage models because the connections can occur while mobile devices are being carried in pockets and briefcases and eliminates the line-of-sight restrictions with some present technologies. Bluetooth, being an open standard, provides a common communication platform that allows completely new combinations of innovative products and new premium features to be added to any mobile devices. This paper describes the network fundamentals of the Bluetooth system and gives an overview of its operation principles. The discussion begins with the physical aspects of Bluetooth radio and the transmitter and receiver characteristics. With the focus on the radio architecture and network topology, we can see how the system is designed to support ad hoc connectivity and multiple access, and appreciate the efforts in combating interference from external sources. Based on the technical concepts, the study also discusses the use of access code correlator in Bluetooth transceivers for signal decoding and time synchronization. The impacts of multipath fading and interference from noise to the time synchronization performance are evaluated as well. The last section gives a general comparison between Bluetooth and the other competing technologies available, and a brief look at Bluetooth products and market potentials in the near future.en_US
