Despite their weakness, Bluetooth signals don't require line of sight between devices. The radio waves will travel through walls easily, and their low power helps to reduce the chance of interference from other technologies that use radio waves, such as baby monitors and garage door openers.How strong is Bluetooth signal?
Bluetooth® technology supports transmit powers from -20 dBm (0.01 mW) to +20 dBm (100 mW).What does wrapping your phone in tin foil do?
Effect. Wrapping a cell phone in aluminum foil creates a Faraday cage. Because cell phone signals are electronic, the aluminum foil prevents the signal from reaching the cell phone.Does tin foil block WIFI?
