2. Prepared By: Prof. Maulik Patel 2 Bluetooth Radio frequency identification(Rfid) Wireless Broadband, etc.

3. Prepared By: Prof. Maulik Patel 3 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. Bluetooth

4. Prepared By: Prof. Maulik Patel 4 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. Bluetooth
