Posted by admin in Bluetooth is a short-range communications protocol which allows various devices to connect wirelessly. The Bluetooth baseband protocol is a grouping of circuit and packet switching. Bluetooth technology was conceived by Ericsson, but was founded and developed by Ericsson, Nokia, IBM, Intel and Toshiba. This consortium is called the Bluetooth Special Interest Group (SIG). Bluetooth wireless technology was designed from the inception to support both data and multiple voice channels over 10 meters range.
Unlike infrared, Bluetooth does not require line-of-sight. The omnidirectional capability of Bluetooth allows synchronization to occur instantly. Its ability to penetrate solid objects and communicate with other devices in a “piconet” allows for data exchange opportunities that are very difficult with infrared.
Current Bluetooth technology provides data transfer at a speed of 1 Mbps, with a personal area range of upto 10 m in client-to-client open air. For client-to-access point, the range is 100m in open air and 30 m in buildings. To set up Bluetooth, you need to switch it on and locate the Bluetooth devices within range.
Bluetooth is implemented in short-range transceivers embedded in mobile devices or added in an adapter device such as PC card. Bluetooth uses the unlicensed global ISM (industrial, scientific and medical) radio bands of 2.4 GHz.
Bluetooth can be found in a variety of products like telephones, watches, playstations, modems, headsets and mobile phones. Bluetooth devices are intended to substitute wired connections between computers, peripherals and other electronic devices. The range of Bluetooth devices can be extended by using optional amplifiers.
