1. A method performed by a positioning system for determining the location of a mobile communication device (MCD), the method comprising:

  • determining a cell in which the MCD is located, the determined cell being served by a serving base station connected to a set of radio heads, wherein each one of the radio heads included in the set of radio heads is connected to the base station via a cable, and one of the radio heads included in the set is serving the MCD;

    determining a cable length value representative of the length of the cable connecting the base station to the radio head serving the MCD; and

    obtaining one or more measured radio property values;

    forming a fingerprint using both the determined cable length value and the obtained measured radio property values; and

    using the formed fingerprint to obtain location information for the MCD, wherein the obtained location information is associated with the formed fingerprint and comprises at least;

    i) a set of polygon coordinate vectors or ii) a set of coordinates derived from the set of polygon coordinate vectors.
