## 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

### Claim 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.

### Claim at position 2
