Free Essays on Bluetooth

Introduction The purpose of this research is to overview of the Bluetooth concept. It strives to cover Bluetooth technical aspects and Bluetooth applications. The document begins with an introduction to describe the Bluetooth background and the Bluetooth standardization organization. Next, the Bluetooth technology will be discussed. Bluetooth protocol layers and their configuration are described in the Bluetooth architecture section. Moreover, a number of usage models will be presented. Finally, the document will be concluded by a summary section. Background Bluetooth technology is a global standard that eliminates wires and cables between both stationary and mobile devices. It also facilitates both data and voice communication and offers the possibility of ad hoc networks and delivers the ultimate synchronicity between all personal devices. The idea that resulted in the Bluetooth wireless technology was born in 1994 when Ericsson Mobile Communications decided to investigate the feasibility of a low-power, low-cost radio interface between mobile phones and their accessories. The Bluetooth wireless technology comprises hardware, software and interoperability requirements. It has been adopted not only by all major players in the telecom, computer and home entertainment industry, but also in such diverse areas as the automotive industry and healthcare, automation and toys, etc. – almost all sectors of the economy. The technology The Bluetooth Specification defines a short (around 10 m) or optionally a medium range (around 100 m) radio link capable of voice or data transmission to a maximum capacity of 720 kbps per channel. The Bluetooth technology supports both point-to-point and point-to-multipoint connections. Radio frequency operation is in the unlicensed industrial, scientific and medical (ISM) band at 2.4 to 2.48 GHz, using a spread spectrum, frequency hoping, full-duplex signal at up to 1600 hops/sec. The signal hops among 79 fre... Free Essays on Bluetooth Free Essays on Bluetooth Introduction The purpose of this research is to overview of the Bluetooth concept.

The introduction of Bluetooth products has been much slower than 802.11 products. The introduction of Bluetooth in May of 1998 was the result of several companies, such as Ericsson, IBM, Intel, Nokia, and Toshiba, working together to create a solution to provide wireless access to computing devices. The result is considered ideal for small devices, short range, and low power radio links. This makes Bluetooth a good fit for connecting PCs and laptop computers, phones, printers, PDA’s, and cameras. IEEE has made Bluetooth the basis for the 802.15 standard for wireless personal area networks. Bluetooth operates in the 2.4GHz band, using frequency hopping spread spectrum technology. It constantly hops over the entire spectrum at a rate of about 1,600 hops per second. Low power Bluetooth devices have a range of about 30 feet. Higher powered Bluetooth devices, however, can reach distances of around 300 feet, but this is fairly rare. One major downfall of Bluetooth is its relatively slow operation. Data rates are only a couple of megabits-per-second (Mbps), well below that of 802.11a and 802.11b. The 802.11 standard was completed in June of 1997 and is the basis of the Wi-Fi standard. Since then there have been some additions to the standard, namely 802.11a and 802.11b. Right now 802.11b is the most popular version, operating in the 2.4GHz spectrum with maximum data rates of 11Mbps and a range of about 300 feet. 802.11a is much faster than 802.11b at 54Mbps but has somewhat less range because of operation in the higher frequency 5GHz band. But there is significant competition for the market between 802.11 and Bluetooth, because higher powered Bluetooth components are capable of achieving 802.11 ranges. The current Bluetooth products, however, are mostly low power and focus on wireless functions. In ad...
