The present invention relates to a
system for position detection, implementing RF-based
distance measurement, the
system comprising at least one transmitting unit (12) arranged for transmitting an electromagnetic wave
signal in the RF range, at least one receiving unit (14) arranged for receiving an electromagnetic wave
signal in the RF range, wherein the transmitting unit (12) is arranged to transmit an electromagnetic wave
signal specifically formed for
distance measurement, and wherein the receiving unit (14) is arranged to receive the electromagnetic wave signal transmitted by the transmitting unit (12) in a direct or mediate fashion, at least one control device (30) for
distance measurement based on transmitted signal information and received signal information, the control device (30) further comprising a distance measurement
quality assessment unit (32), and a
power consumption optimizing unit (34), wherein the distance measurement
quality assessment unit (32) is arranged to derive a distance measurement quality indicator, based on distance measurement results, and wherein the
power consumption optimizing unit (34) is arranged to adapt at least one transmitting parameter, based on the quality indicator.
