Abstract

An apparatus for determining a coincidence of a position with a reference position, wherein radio signals from fixedly positioned radio transmitters can be received at the position, having a provider for providing properties of the radio signals of the fixedly positioned radio transmitters at the position, wherein the provided properties of the radio signals include transmitter identifications identifying the radio transmitters, a separator for separating the radio transmitters into a first number of radio transmitters previously recorded transmitter identifications of which at the reference position are identical with transmitter identifications provided at the position, and into a second number of radio transmitters previously recorded transmitter identifications of which at the reference position and transmitter identifications provided at the position are different, and a determiner for determining a measure of matching for the position on the basis of the provided properties of the radio signals, wherein both properties of the first number of radio transmitters and properties of the second number of radio transmitters are taken into account in the determination of a measure of…
