A system for providing location relevant information to users (1) of a plurality of mobile devices (2) within a multistorey building. A plurality of transmitters (4-13) are located in different locations across multiple floors (14), (15), (16) of the building. Each transmitter (4-13) transmits a signal for identifying the location of its associated transmitter and signals transmitted at least by transmitters located on the same floor share at least one common transmission parameter. The mobile devices (2) each run software that identifies signals received substantially concurrently from the transmitters (4-13), determining the closest transmitter (4-13), and then displays on the mobile device (2) location relevant information associated with that location. |
