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: Examples of a system and wireless RF device having an extended operational life are provided. The wireless RF device includes a substrate, at least one sensor configured to detect an occurrence of an event, a RF transceiver arranged on the substrate and configured to transmit and receive RF signals in an area, and a power supply coupled with the substrate. A processing device is coupled to the at least one sensor and the RF transceiver, and configured to: in response to expiration of a time period or the detection of the occurrence of an event, transition the RF device from a sleep or standby mode to an active mode; configure the RF transceiver to receive or transmit a data packet; obtain a status of an occurrence of another event from the at least one sensor; and transition the RF device from the active mode to the sleep or standby mode.

Abstract: Described examples include light fixtures and/or radio frequency (RF) nodes located in a service volume provided with a mobile asset detection system. The RF nodes receive beacon signals transmitted by mobile assets within the service volume. The mobile asset detection system includes a processor, a transceiver and multi-element antenna array. The multi-element antenna array includes multiple discrete antenna elements that, in some examples, are arranged so that at least one of the discrete antenna elements is non-coplanar with the other discrete antenna elements of the antenna array. Using signal attribute values determined from a signal received via each of the respective discrete antenna elements, a three dimensional estimate of the location of the mobile assets in a service volume may be determined.

Abstract: An example radio frequency (RF) positioning node system calculates a respective distance between an uncommissioned RF positioning node to each of neighboring commissioned RF positioning nodes based on a respective received signal strength indicator (RSSI) measurement. Based on the calculated respective distance to each of the neighboring commissioned RF positioning nodes and a set of commissioned location coordinates of each of the neighboring commissioned RF positioning nodes, the RF positioning node system estimates a set of uncommissioned location coordinates of the uncommissioned RF positioning node. The RF positioning node system determines a best fit assignment of the set of uncommissioned location coordinates of uncommissioned RF positioning nodes in an uncommissioned RF positioning node list to the set of commissioned location coordinates of non-operational commissioned RF positioning nodes in a non-operational RF positioning node list to adjust an RF positioning node map for each of the non-operational commissioned RF positioning nodes.

Abstract: A tag is configured to provide information that enables a processor or other computing device to locate the tag and any asset associated with the tag in an area. The tag incorporates a motion sensor responsive to movements of the tag above a predetermined rate and a predetermined magnitude. In response to the movements above the predetermined rate and magnitude, the motion sensor generates a voltage exceeding a predetermined threshold. An energy-saving process exploits the tag's microcontroller's transitions between a “sleep” state and an “awake” state. While asleep, the microcontroller maintains a clock and data in memory, and monitors an input from the motion sensor. In response to voltages at the input over the predetermine threshold, the microcontroller receives signals from one or more nearby beacon nodes in a network operating in the area, process the signals and transmit information based on the processed signals, for a position determination.

Abstract: In an example, a method comprises communicating with a radio frequency (RF)-enabled asset tag within a space, tracking a location of the RF-enabled asset tag within the space, determining location estimates of the asset tag as the asset tag moves within the space, and accepting identifying information from or about a selected user. The method additionally comprises determining, based on a predetermined correspondence criteria, a correspondence between the asset tag location and a position estimate of an electronic hardware device within the space. Further, in response to determining the correspondence between the asset tag and the electronic hardware device and based at least in part on the identifying information accepted via the electronic hardware device, the method includes associating tracked asset tag location information corresponding to the location estimates of the asset tag as the asset tag moved within the space to identification of the selected user.

Abstract: An example method includes propagating a message including an instruction, from a gateway to a plurality of ancillary nodal devices (devices) in a flood network. Each of the plurality of devices is within an equal number of transmissive steps of the gateway through the flood network such that the message is propagated with approximately equivalent delay to each of the plurality of devices and substantially simultaneously received by all of the devices. The method also includes substantially simultaneously transmitting the message from each respective one of the devices to end nodal devices (end nodes) of a group of end nodes in the flood network in communication with the respective one of the devices. The method further includes, upon receipt of the message from the devices, substantially simultaneously executing the instruction, by each of the group of the end nodes of the flood network.

Abstract: A system includes a plurality of lighting devices connected in a network to communicate in a service area, and a smart tag configured to communicate with one or more of the lighting devices. Each respective lighting device is configured to transmit a radio frequency signal including a device identifier of the respective lighting device. In response to expiration of a time period or an occurrence of an event, the smart tag is configured to transition from a low power consumption sleep mode to an awake mode. During the awake mode, the smart tag is configured to provide information that enables a processor or other computing device to determine a position of the smart tag or any asset associated with the smart tag in the service area. Upon transmission of the information, the smart tag is transitioned from the awake mode back to the low power consumption sleep mode.

Abstract: The disclosure provides examples of systems and methods for determining locations of a number of radio frequency-enabled devices such as mobile devices and radio frequency-equipped beacons/luminaires within an indoor location. The radio frequency-enabled devices may be part of an indoor positioning system and/or content delivery system. The examples describe obtaining an angle of arrival (AoA) of the signals received by the respective radio frequency-enabled devices. The AOA data is used to identify the relative positions of the radio frequency-enabled devices as the mobile device moves about the indoor location. Upon comparing AOA measurements of the collected data related to a map of the location, the system may generate a data structure that may be presented graphically as a map of positions of the devices at the location. The described examples may enable a rapid commissioning process with respect to the radio frequency-enabled devices in a network.
