Abstract: Examples of a system and a method for asset tracking are provided. The system includes wireless communication nodes in a space that receive a basic message including an asset tracking tag identifier and a basic message sequence number transmitted by an asset tracking tag. The wireless communication nodes measure a received basic message signal attribute, and transmit a node asset message including the asset tracking tag identifier, the basic message sequence number, a node identifier, and the measured signal attribute of the received basic message to an edge gateway. The edge gateway may receive the transmitted node asset message transmitted by each of some number of the wireless communication nodes and rank respective node identifiers extracted from the received node asset messages based the measured signal attribute. The edge gateway forwards an aggregated message to a fog gateway for obtaining an estimate of the location of the asset tracking tag.

Abstract: 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.

Abstract: An example of a technique for compensating for effects of Earth's magnetic field variations on a mobile device positioning system. A mobile device utilizes a compass to obtain an absolute heading when located relative to a visible light source. The mobile device obtains a heading correction value based on an identifier of the visible light source. An orientation of a map displayed on the mobile device is rotated based on the absolute heading and the heading correction value in order to provide an indication of a location of the mobile device properly oriented on the map.

Abstract: In a positioning system, a mobile device can detect a transmission from one of a number of lighting devices to obtain an identification (ID) label or code of each lighting device. The mobile device uses the detected ID code for a lookup in a self-stored or remotely stored table that associates lighting device location information with ID codes, to obtain an estimate of mobile device position. To mitigate against hacking by a third party detecting the ID codes and observing locations to compile its own lookup table, the disclosed examples dynamically alter the assignments of particular ID codes to the lighting devices, while minimizing potential disruption of position determination service for mobile devices due to the changes to ID code assignments.

Abstract: An example of a lighting device including a light source, a modulator and a processor. The processor is configured to control the light source to emit light for general illumination and control the modulator to modulate the intensity of the emitted light to superimpose at least two sinusoids. Frequencies of the at least two sinusoids enable a mobile device to infer the physical location of the lighting device.
