Abstract
A method of determining the location of a portable device comprises obtaining identities of wireless communication devices detectable by the portable device at a particular location which is to be determined, thereby to obtain a set of identities. The set of identities is compared with the content of a database, which database stores a plurality of findings, to select one or more findings; each finding comprising a reference location and a set of identities of wireless communication devices sighted at that location. The location of the portable device is found based on processing the selected findings.
