Abstract

A system for providing locality information to a user is disclosed. The system comprises at least one magnetic field beacon. Each beacon comprises means for generating a magnetic field encoded with information associated with the beacon. A communication device is provided that comprises means for detecting the encoded magnetic field emitted by the beacon and means for extracting the information encoded in the detected magnetic field.

Claims

1. A communication system for providing information to a user of a mobile telephone, the system comprising:

a beacon comprising;

means for generating a magnetic field having a time-varying magnetic field vector, wherein said time-varying magnetic field vector is modulated to encode information associated with said beacon; and

a mobile telephone comprising;

means for detecting the magnetic field having the time-varying magnetic field vector generated by the beacon; and

means for extracting said encoded information from said detected magnetic field.
