When the location type is rssBasedLocation it is likely that
there will be a number of probable locations calculated for
one station. This table lists the most recently
rssBasedLocation-calculated probable locations of each
tracked station. Each row of the table represents one probable
location of one tracked station. The table is indexed by the
subject station's MAC address and an internal identifier for
the cell described by the entry. The cell is a cell on the floor
identified by the etsysTrackedStationFloorID object in the
etsysTrackedStationEntry for the subject station.
