The technology of Bluetooth wireless is a shortrange communications method intended to replacethe cables that connect portable or fixed deviceswhile maintaining the highest levels of security.
The key features offered by Bluetooth includelow power and low cost. The specification inBluetooth defines a uniform structure for a widerange of devices to communicate and connect withone another.
The technology behind Bluetooth has achievedglobal satisfaction such as enabled devices, almosteverywhere in the world. Bluetooth devices willconnect and communicate without wires throughshort range and networks known as piconets.
Each device willsimultaneously communicate withup to seven other devices within a single piconet,meaning that each device can also belong toseveral piconets simultaneously. The piconetsare dynamically established as Bluetooth enableddevices enter and leave the proximity of radio.
A fundamental to Bluetooth strength is theability to handle both data and voice transmissionssimultaneously. This will enable users to enjoyvarieties of innovative solutions such as handsfree talking, printing and fax capabilities,and other applications.
Specifications Unlike other standards of wireless, the Bluetoothspecification gives product developers both alink layer and application layer definitions,which will help support data and voice applications. Spectrum The Bluetooth technology operates in the industrialand scientific band at 2.4 to 2.485 GHz, using aspread spectrum, frequency hopping signal.
Interference The adaptive frequency hopping of Bluetoothtechnology was designed to reduce interferencebetween wireless technologies that share the 2.4GHz spectrum. Adaptive frequency hopping (AFH)works well within the spectrum to take fulladvantage of the frequency available.
AFH hopping allows for more efficient transmissionwithin the spectrum, which provides users withgreater performance even if they are using othertechnologies along with Bluetooth.
