Adaptive personal identification device for mobile telephone

摘要

A method adapts a signal transmitted by a mobile telephone. Simulated telephone activity to be transmitted as a radio signal by the mobile telephone is generated in a hands-free kit to be plugged into a voice or data connector of the mobile telephone. The mobile telephone transmits the simulated telephone activity as a radio signal. The radio signal is detected by an antenna of the hands-free kit. The detected radio signal is then used to adjust the simulated telephone activity as it is being generated. The adjusting can alter the timing and amplitude of the simulated telephone activity to conform to an air interface standard of the radio signal.
