Abstract
An apparatus for determining the distance from a transmitter to a receiver is proposed, wherein the transmitter and the receiver are configured to communicate via a radio channel. The apparatus comprises at least one measuring unit configured to measure a received signal strength indicator value and a time-of-flight value of the radio channel. The apparatus further comprises a processing unit configured to compare the measured pair of the received signal strength indicator value and the time-of-flight value with stored pairs of received signal strength indicator values and time-of-flight values, wherein the stored pairs of received signal strength indicator values and time-of-flight values are each associated with a distance of the transmitter to the receiver, and wherein the processing unit is configured to determine the distance of the transmitter to the receiver based on the comparison result.
