In one aspect, the system includes a plurality of transmitters, each transmitter having associated therewith a reflector antenna configured to substantially reflect signal transmission toward a detection area; and a mobile device configured to: receive transmitter signals from at least two transmitters from the plurality of transmitters; and determine that the mobile device is located within the detection area based on received signal strengths of the at least some of the transmitter signals.

An indoor positioning system for fireman includes: a wireless tag reading device, worn or carried by a fireman; and a plurality of wireless tags, disposed in a plurality of positioning points defined in an indoor space and each of the wireless tags having a memory for storing a location data, where each of the location data is corresponding to one of the plurality of positioning points; when in use, the wireless tag reading device is coupled with at least one of the plurality of wireless tags within a sensing range via a wireless means, so that at least one of the location data corresponding to at least one positioning point defined in the indoor space is obtained.

The present invention discloses a direction-finding chip, a direction-finding method and a beacon. The direction-finding chip is applied to a beacon of a direction-finding system. The beacon includes multiple antennas and an inertial measurement unit (IMU). A mobile device can calculate angle information according to supplement provided by the beacon. The direction-finding chip includes a computation circuit and a radio frequency circuit. The computation circuit generates coordinate conversion information or a correction amount of the coordinate conversion information according to an acceleration and a magnetic field vector generated by the IMU. The coordinate conversion information or the correction amount can be used to compensate the angle information. The radio frequency circuit is coupled to the computation circuit and configured to transmit the supplement and the coordinate conversion information or the correction amount.

A system and method of acquiring and maintaining location information associated with traffic apparatus deployed in connection with a traffic flow monitoring or regulation system are disclosed. In some implementations, an apparatus identifier may distinguish a particular traffic apparatus from others that are deployed in proximity, and a functional identifier may define a functionality of the particular traffic apparatus; positioning, orientation, and movement or acceleration data may also be provided for real-time or near real-time system applications. These apparatus data may be used to derive and to maintain a record of location data associated with each traffic apparatus deployed in a particular application.

A localization system comprising a plurality of wireless reference nodes for detecting a location of a mobile device within an environment. Each node transmits localization beacon signals to be detected by the mobile device, and/or listens for localization beacon signals from the mobile device. Further, the system also provides or contributes to providing another utility into the environment (e.g. each node being a luminaire); and transmits and/or listens for control-related signals, other than localization beacon signals, related to controlling the provision of said utility, the control related signals being communicated on a same or overlapping frequency band as the localization beacon signals, one or more controllers are configured to control the transmission of and/or listening for the control-related signals to be time-multiplexed into different time slots than the transmission and/or listening for the localization beacon signals, between the time-slots of the control-related signals.

Administration and consistency of proximity beacon naming within one or more venues is improved by use of a mobile device to discover ranges of the beacons, and upon discovery, determining a location of a mobile computing device within the venue; receiving at the location by the mobile computing device one or more identifiers from one or more proximity beacons within range of the location; and updating by the mobile device at least one of the one or more identifiers according to a proximity beacon naming policy.

Disclosed in some examples are methods, systems, devices, and machine-readable mediums for providing a PNT system provided by stratospheric balloons. This stratospheric PNT system (SPNTS) replaces the space-segment of a standard PNTS with a stratospheric segment comprising one or more stratospheric balloons that provide PNTS signals usable to determine timing, positioning, and/or navigation for user devices.
