By Group ‘3’ BLUETOOTH Bluetooth is an open wireless technology standard for exchanging data over short distances from fixed and mobile devices creating PAN’s with high level security. Created by ERRICSON in 1994 Bluetooth started as a code name for association when it was formed. It evolved from the epithet of Danish King Harold who united many warring fractions of land together. Blue tooth is a packet based protocol with a master slave architecture. Specifications for Bluetooth are developed by Bluetooth Special Interest Group (B-SIG). B-SIG was formed in 1998, Head Quarters : Washington The Bluetooth SIG includes Promoter member companies Ericsson, Intel, Lenovo, Microsoft, Motorola, Nokia, and Toshiba, and more than 13,000 Associate and Adopter member companies. Integrates telecommunication, computing , networking & Consumer electronics Industry. Mission Statement : Strengthen the Bluetooth brand by empowering SIG members to collaborate and innovate, creating the preferred wireless technology to connect diverse devices. Diversity of Bluetooth Products Audio & Visual Headsets Automotive Home environment Gaming Mobile Phone Office Equipment TECHNICAL FEATURES Network Arrangements Bluetooth networks can be either point to point or point to multi-point. Any unit in a Pico net can establish a connection to another Pico net to form a scatter net. Bluetooth arrangements are only between two Pico nets Parts of a Bluetooth network Piconet Scatternet Master Slave Unit Unit Mac Address Bluetooth characteristics It separates the frequency band into hops. This spread spectrum is used to hop from one channel to another, which adds a strong layer of security. Up to eight devices can be networked in a Piconet. Devices do not need to be pointed at each other, as signals are Omni-directional Both synchronous and asynchronous applications are supported, making it easy to implement on a variety of services, such as voice and internet. Governments worldwide regulate it, so it is possible to utilize the same standard whenever one travels. COMPETING TECHNOLOGIES COMPETING TECHNOLOGIES • Wireless Lan WLAN based on IEEE 802.11b standards are used to replace the wired LAN. Adv: Transmission capacity and the number of simultaneous users are high. Dis: Compared to Bluetooth they are more expensive, consume more power and requires large hardware setup making them unsuitable for smaller devices BLUETOOTH IN THE FUTURE • The Bluetooth technology is expected to provide greater bandwidth and distances. • Hence increasing potential platforms and applications used in personal area network marketplace. BLUETOOTH IN THE FUTURE • This technology was used in as many as 670 million products. • Based on the request of Bluetooth SIG (Special Interest Group), the range and speed of Bluetooth connectivity is expected to increase. • In addition to improving safety as a result of eliminating clutter of wire Bluetooth and associated hazardous connection Devices are , Bluetooth wireless technology also wireless offers you many convenient advantages. • Bluetooth technology is cheap for the companies to implement, which Bluetooth results in lower the overall technology manufacturing costs. These savings is are then passed on to consumers. The Inexpensive end result the Bluetooth devices are relatively inexpensive. • When two or more Bluetooth devices enter a range (Up to 10 meters) of one Bluetooth is another, they automatically begin to Automatic communicate without you having to do anything. • Bluetooth uses low power signals. As a Low energy result, the technology requires little consumption energy and will therefore use less battery or electrical power. Share • Bluetooth standards allows Voice and compatible device to share both Data voice and data communication. Accessible • Though Bluetooth device has a From specific range but we can access Anywhere up to wide range.
