A computing arrangement for determining a location of a wireless
communications device includes a memory arrangement, a communication
arrangement and a processor. The memory arrangement stores a location of
each of at least three access points. The communication arrangement
receives first data which includes at least one of first signal strength
data and second signal strength data. The first signal strength data is
indicative of a strength of a first signal transmitted by the device and
received by the at least three access points. The second signal strength
data is indicative of a strength of a second signal transmitted by the at
least three access points and received by the device. The processor
determines a location area of the device as a function of the first data
and the location of each of the at least three access points, the
location area being within a predetermined reception range of the at
least three access points. The processor determines the location of the
device within the location area as a function of second data. The second
data is indicative of a travel time of a third signal from the device to
each of the at least three access points.
