The range at which a Bluetooth device can transmit depends on several factors. Understanding the ranges helps you be aware of whether a Bluetooth-enabled device could be the victim of a bluejacking or bluesnarfing attack. Go to www.bluetooth.com/learn-about-bluetooth/bluetooth-technology/range/ to explore the Bluetooth Range Estimator tool. First, watch the video and then read the details of each of the key factors. Then use the range estimator tool, changing the different parameters (receiver sensitivity, path loss, transmit power, transmitter antenna gain, and receiver antenna gain) to determine the estimated range. What does this tell you about Bluetooth ranges? How could this tool be used?
