Abstract

A portable device (100) communicates with a short range wireless local area network (114) and a wide area communication system (116). The portable device (100) receives a location data from the short range wireless local area network (114). The portable device (100) generates a location sensitive information request to the wide area communication system (116) including the location data received from the short range wireless local area network (114).
