Abstract
A method of determining the location of a plurality of tagged items in a storage system comprises scanning () for tags with a first antenna at a plurality of power levels, analysing () the scan to identify each tag of interest sighted by the first antenna at each power level of the plurality of power levels, and scanning () for tags with at least one further antenna at a plurality of power levels. The method further comprises analysing () the further scan to identify each tag of interest sighted by each further antenna at each power level of the plurality of power levels, further analysing () the scan to determine the antenna with the lowest power level that identified each tag of interest, and estimating a position () of each tag of interest using the determined antenna and the lowest power level that identified that tag.
