A system for hands-free access to a vehicle includes a hands-free access device that transmits a location frame of a modulated signal and a pure carrier signal, receives a measurement of a received signal strength of a primary received signal performed on the pure carrier signal by a hands-free identifier, and receives information on an absence or presence of noise in the location frame. Additionally, the hands-free access device authorizes or prevents access to the vehicle. The system further includes a hands-free identifier that receives the location frame, performs a measurement of the received signal strength of the primary received signal on the pure carrier signal, sends the hands-free access device the measurement of the received signal strength of the primary received signal, checks the presence of noise in the location frame, and sends the hands-free access device information on the absence or presence of noise in the location frame.
