Bluetooth technology - Essay Example The Bluetooth technology works across a secure and unlicensed short-range radio frequency. Bluetooth technology sends information within our own personal space which is known as our Personal Area Network (PAN) at distances of up to 10 meters. Bluetooth is also known as the IEEE 802.15.1, an industrial standard for wireless PANs (personal area network), since it can be used in smaller offices with few employees (Peter, 2006). A product having Bluetooth facility means that it some hardware or small computer chip along with some software that lets one product connect wirelessly to another using the Bluetooth technology. History of Bluetooth: The Bluetooth technology was formulated in 1994 by the Engineers of a company called â€Å"Ericsson†, a Swedish company. The reason behind this invention was to eradicate the rummage in homes and offices. In 1998, Bluetooth Special Interest Group (SIG) was developed and its founding members were Ericsson, Intel, IBM, Nokia and Toshiba. The mo tive behind was to connect their products and also the organization devoted its time in maintaining the Bluetooth technology. Within six months success of the Bluetooth technology many other companies joined in this new invention. Since then the Bluetooth technology has boomed and has been adapted by many other companies. ... the King’s work, Bluetooth is all about connecting and communicating in an uninterrupted single flow allowing different devices from cell phones to automobiles to communicate and network with each other. The Bluetooth Logo is established on the H and B of Harold's name. How the technology works: Initially the range of Bluetooth device brooded over 5meters but now it can attain a range of 10meters after expanding into 700-800kb bandwidth. The transmission frequency range for Bluetooth is between 2.4 and 2.4835 GHz with a maximum transfer speed of 2 Mbps per second whereas at the beginning it was around 1Mbps per second and the frequency range was 2GHz. Bluetooth technology functions in the unlicensed industrial, scientific and medical (ISM) band. It uses a spread spectrum, frequency hopping, full duplex signal at a nominal rate of 1600 hops/sec (Justin, 2004). The network of Bluetooth contains a powerful topology PAN (personal area network) also known as piconet. These piconets are established dynamically and automatically. Nodes are organized in small groups of piconets. Every piconet has a leading node known as master and other nodes in a piconet are referred as slaves. A node can belong to a multiple of piconets, and such a node is called as a bridge. Piconet contains a minimum of two and a maximum of eight peer devices. The devices will communicate using protocols that are part of the specification. Slaves do not directly communicate with each other but instead rely on the master as a carrying node. Bluetooth provides a half-duplex communication channel. Communication between nodes in different piconets involves the bridge nodes. A bridge node can’t be active in more than one piconet at a time. It is active in one piconet while being deposited in others. Data
