Abstract: In one embodiment, a supervisory service for a wireless network obtains frequency-time Doppler profile information for an endpoint node attached to a first access point in the wireless network. The supervisory service uses the frequency-time Doppler profile information for the endpoint node as input to a machine learning model. The machine learning model is trained to output an action for the endpoint node with respect to the wireless network. The supervisory service causes the action for the endpoint node with respect to the wireless network to be performed.

Abstract: A computer-implemented method includes first collecting, from wireless devices at known locations in a venue, first ultra wideband (UWB) location measurements obtained using a first location technique based on first UWB transmissions made by a mobile device at a first rate. The method also includes second collecting, from the wireless devices, second UWB location measurements obtained using a second location technique based on second UWB transmissions made by the mobile device at a second rate. The method further includes detecting that the mobile device is in a first UWB coverage hole for the venue with respect to the first UWB location measurements based on a first UWB coverage hole criterion. The method also includes, based on detecting, increasing the second rate relative to the first rate to obtain additional second UWB location measurements using the second location technique to compensate for the first UWB coverage hole.

Abstract: Automatic onboarding of a device onto a cellular network may be provided through a Wireless Local Area Network (WLAN). Subsequent to a device connecting to a first network (e.g., the WLAN), information associated with the device and the first network may be received. One or more tags may be generated and an intent profile may be defined for the device based on the received information, where the intent profile may indicate at least a second network (e.g., the cellular network) that the device is enabled to connect with and one or more policies associated with the connection. The tags and intent profile may be transmitted to a service provider platform, and an onboarding profile template identified using the tags and the intent profile may be received from the service provider platform. The onboarding profile template may be provided to the device to enable connection to the second network.

Abstract: Presented herein are techniques for assigning Ultra-Wideband (UWB) anchors for client ranging. A control device can monitor UWB ranging between a mobile device and a primary anchor. In response to determining that a signal strength between the mobile device and the primary anchor is below a threshold, the control device can identify anchors for which the mobile device has had a signal strength above the threshold during a period of time, and select one of the anchors as a new primary anchor for the mobile device. For example, the control device can select the new primary anchor based on a relative collision tolerance mapping for the new primary anchor and at least one other anchor within a UWB range of the new primary anchor. The control device can send a command causing UWB ranging to be performed between the mobile device and the new primary anchor.

Abstract: In one embodiment, a method comprises: determining, by a constrained network device in a low power and lossy network (LLN), a self-estimated density value of neighboring LLN devices based on wirelessly receiving an identified number of beacon message transmissions within an identified time interval from neighboring transmitting LLN devices in the LLN; setting, by the constrained network device, a first wireless transmit power value based on the self-estimated density value; and transmitting a beacon message at the first wireless transmit power value, the beacon message specifying the self-estimated density value, a corresponding trust metric for the self-estimated density value, and the first wireless transmit power value used by the constrained network device for transmitting the beacon message.

Abstract: A method includes obtaining performance characterization values from endpoints managed by a first fog node at a first hierarchical level in a hierarchy of fog nodes. The method includes changing a first operating characteristic of the wireless network based on the performance characterization values. The first operating characteristic affects the operation of one or more of the endpoints. The method includes transmitting a portion of the performance characterization values to a second fog node at a second hierarchical level in the hierarchy of fog nodes. The method includes changing a second operating characteristic of the wireless network based on an instruction from the second fog node. The second operating characteristic affects the operation of the first fog node and/or other fog nodes at the first hierarchical level. Changing one or more of the first operating characteristic and the second operating characteristic satisfies an operating threshold for the wireless network.

Abstract: A server, in communication with a plurality of microservices in a microservices mesh environment, obtains data about inbound communications to a first microservice and outbound communications from the first microservice of the plurality of microservices. The server analyzes the data to learn an operational behavior of the first microservice and determine a firewall rule set to be applied associated with the first microservice based on the operational behavior learned for the first microservice. The server causes a micro-firewall to be instantiated for the first microservice. The micro-firewall is configured to apply the firewall rule set to inbound communications to the first microservice and outbound communications from the first microservice.

Abstract: Presented herein are techniques that aggregate messages using a subroot node. A plurality of messages is received from a corresponding plurality of nodes by a subroot node acting as a proxy in a wireless mesh sub-network. The plurality of messages is aggregated into a single message according to a template. The single message is wireless transmitted to a root node, wherein the root node has a wired connection to a network.

Abstract: A network controller automatically adjusts a computer network based on the operational information of an industrial device. The network controller receives a notification from a network element in the computer network that the industrial device attached to the network element has an administrative shell. The administrative shell includes operational information describing the operation of the industrial device. The network controller retrieves the administrative shell from the industrial device. The network controller parses the operational information in the administrative shell to determine an intent for the industrial device, and adjusts the computer network based on the intent of the industrial device.
