SYSTEM AND METHOD FOR COMMUNICATION WITH A MOBILE DEVICE VIA A POSITIONING SYSTEM INCLUDING RF COMMUNICATION DEVICES AND MODULATED BEACON LIGHT SOURCES

摘要

A light source emits a modulated light, and a radio-frequency transceiver disposed therewith emits a radio-frequency signal. A mobile device may receive either or both signals and determine its position based thereon. The light and radio-frequency sources may be disposed in node in a network of said sources, and the nodes may communicate via the radio-frequency transceivers.

主权项

1. A mobile device, comprising:
a radio frequency transceiver; a hardware user interface; a camera configured to receive a visual light communication; and a processor configured to:
receive a radio frequency identifier of a lighting device via the radio frequency transceiver;receive via the camera a modulated light identifier of a lighting device in the vicinity of the mobile device;combine the radio frequency identifier and the modulated light identifier to form a combined lighting device identifier; andreceive position information related to the mobile device based on the combined identifier.
