System for providing location relevant information

Software for a mobile device for providing location relevant information within a multi-storey building, the software comprising operable instructions for:

• identifying signals received substantially concurrently from two or more of a plurality of transmitters located in different locations across multiple floors of the building, each transmitter transmitting a signal for identifying the location of its associated transmitter, and wherein signals transmitted at least by transmitters located on the same floor share at least one common transmission parameter;
• and
• determining the closest transmitter on the same floor as the mobile device based at least in part on the at least one common transmission parameter of received signals from the two or more of the plurality of transmitters;
• and
• displaying on the mobile device location relevant information associated with the location of the determined closest transmitter.

A mobile device for providing location relevant information within a multi-storey building, the mobile device comprising:

• a receiver;
• a display;
• a processor;
• and
• a memory, the memory having stored thereon instructions for processing by the processor, the instructions for:
• identifying signals received at the receiver substantially concurrently from two or more of a plurality of transmitters located in different locations across multiple floors of the building, each transmitter transmitting a signal for identifying the location of its associated transmitter, and wherein signals transmitted at least by transmitters located on the same floor share at least one common transmission parameter;
• and
• determining the closest transmitter on the same floor as the mobile device based at least in part on the at least one common transmission parameter of received signals from the two or more of the plurality of transmitters;
• and
• displaying on the display location relevant information associated with the location of the determined closest transmitter.

A method for providing location relevant information to users of a plurality of mobile devices within a multi-storey building, the method comprising:

• locating a plurality of transmitters in different locations across multiple floors of the building;
• transmitting a signal for identifying the location of its associated transmitter from each transmitter, wherein the signals transmitted at least by transmitters located on the same floor share at least one common transmission parameter;
• running software on the plurality of mobile devices, the software being operable on each mobile device to:
• identify signals received substantially concurrently from two or more of the plurality of transmitters;
• determine the closest transmitter on the same floor as the mobile device based at least in part on the at least one common transmission parameter of received signals from the two or more of the plurality of transmitters;
• and
• display on the mobile device location relevant information associated with the location of the determined closest transmitter.
