Methods and apparatus for location determination based on dispersed radio frequency tags

A location identification system comprising:

• a location server for receiving transmissions from a plurality of tags arranged in a regions wherein locations are to be identified, each tag emitting an encoded signal identifying the location in which the tag is placed, the location server being operative to store each encoded signal emitted by a tag, the encoded signal being associated with the location in which the tag is placed.

• compiling a sequence of radio frequency tag identification values along a path traveled by the user carrying the wireless device;
• and
• identifying the location of the user as the location arrived at by following a path defined by the sequence.
