Bluetooth It is small microchip & operate in a gobally available frequency band. Use unlicensed 2.4GHz ISM freq. Band. 79 available Bluetooth channels spaced 1 MHz apart from 2.402 to 2.480 GHz. IEEE adapted bluetooth as the 802.15.1a standard. Power level: 1mW covering 10cm, 100mW covering 100 meters. Prepared By: Prof. Maulik Patel
Bluetooth Bluetooth protocol uses the concept of master and slave. Device need to wait till the time the master allows them to talk. The master and slaves together form a piconet. Up to Seven slave device can be set to communicate with master. N/w of piconet is called scatternet. Scatternet formed when device from one piconet also act as a member of another.
