摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： A network has wireless enabled nodes of more than one hardware type. A computing device obtains a software update for one of the node types and sends an announcement of availability through the network. The announcement includes a node type identifier. A node that recognizes the identifier as matching its own hardware type collects the software update through a series of one or more requested packet transfers from the controller. Each packet carrying part of the update also includes the node type identifier. A node of a different type that has received the packets may serve as a source of missing packets to other nodes. Alternatively, nodes needing missing packets can fetch them from the computing device. When the software update is completely received by a node of the identified type, that node reboots and executes the updated software. Any node of another type discards the packets.

摘要： A lighting system employs out-of-band (OOB) commissioning techniques, and includes a plurality of uncommissioned luminaires located in a space and a commissioning device. The commissioning device receives, via a visible light camera, over a VLC communication band, a respective VLC code of a respective uncommissioned luminaire. Commissioning device receives via a radio frequency (RF) transceiver, over an RF commissioning network band, a respective RF identifier of the respective uncommissioned luminaire. In response to receiving the respective VLC code and the respective RF identifier, commissioning device determines whether the respective uncommissioned luminaire is in a candidate luminaire roster of candidate luminaires suitable for commissioning in the space. Based on the determination of whether respective uncommissioned luminaire is in the candidate luminaire roster, commissioning device accepts or rejects commissioning of the respective uncommissioned luminaire in the space.

摘要： The disclosure provides an example of a system and a method for command execution synchronization in a nodal network. In one example, the method includes starting at a first time, propagating a message including an instruction and timestamp, in a nodal network including a plurality of wireless communication nodes (nodes). The timestamp identifies a second time later than the first time by an amount of time equal to or greater than a period of delay expected for propagation of the message through the nodal network to all of the nodes. The method also includes running a software (soft) clock in each of the nodes, the soft clocks being synchronized to within a timing error tolerance value of the soft clocks in other of the nodes and executing, by each respective one of the nodes, the instruction when the soft clock of the respective nodes reaches the second time identified by the timestamp.

摘要： A lighting system includes lighting devices and an update manager. The lighting devices include various hardware versions and/or functionalities. The lighting devices are queried to determine existing hardware versions and/or functionalities. The query is sent via a wireless mesh network of the lighting system. An Over-The-Air (OTA) update includes multiple different lighting device programming images, where each image corresponds to one of the existing hardware versions and/or functionalities. The OTA update is delivered via point-to-point connections between the update manager and some number of lighting devices and/or between the lighting devices. Upon receipt, individual lighting devices determine whether a lighting device programming image is needed and/or which of the lighting device programming images is appropriate.
