ABSTRACT:
A beacon is placed at a specific location, such as a bus stop and has a local communicator which transmits a code to a mobile telephone. The code identifies a predetermined item of information stored on a remote server, such as a bus timetable document. This information is retrieved by the mobile telephone using its network communicator. The mobile telephone then transmits a copy of the information to the beacon which stores it in its cache and also displays the document to its user. A PDA, which lacks a network communicator, is then able to retrieve the cached information directly from the beacon using only its local communicator. The PDA then displays the bus timetable document to its user.
