Abstract:
To determine the distance and/or acoustic quality between a mobile device and a base unit, an acoustic signal is received by a microphone in one of said mobile device and base unit. A correlation of a second signal with the received acoustic signal is determined. An acoustic quality and/or a distance between the mobile device and the base unit is determined based on one or more peaks in the result of the step of determining the correlation.
