Abstract: Techniques for access point (AP) based location computation are disclosed. A target wireless AP, communicatively coupled to a wireless station (STA), is identified. One or more location buddy APs, relating to the target AP, are identified based on the physical locations of the location buddy APs and the target AP. It is determined that a first location buddy AP, of the one or more location buddy APs, is communicatively coupled to the STA, and in response a location of the STA is determined using the target AP.

Abstract: A system and method for optimizing access points (APs) within a network comprises receiving, at a first AP, parameters corresponding to a second AP, and determining that the first AP and the second AP are part a first and a second wireless local area network (WLAN), respectively. The first and second WLANs support client credential sharing allowing seamlessly transitioning of a client device between the first and second WLANs using common credentials. Further, co-channel interference between the first AP and the second AP is detected based on the parameters corresponding to the second AP and parameters of the first AP, and at least one of a channel and transmission power of one or more of the first AP and the second AP is changed in response to the detection of the interference.

Abstract: The presently claimed disclosure is directed to methods that may be implemented at a computer. Methods and systems consistent with the present disclosure may include extending protocols associated with authenticating client (i.e. supplicant) devices and with authorizing those supplicant devices to access a wireless network. These methods may include sending data relating to the failure of an authentication and/or an authorization process to a supplicant device attempting to access a wireless network. Methods discussed within may include securely sending failure codes or reasons to a supplicant device that identify why an authentication or authorization process failed. These methods may include sending messages between a supplicant device, an authenticator device, and an authentication and authorization server. After a first failure, the supplicant device may be able to access the wireless network after a reason or code of that failure has been reported to the supplicant device.

Abstract: According to one or more embodiments of the disclosure, a device in a network obtains parameters for entropy testing of industrial equipment that controls a physical process. Entropy is added to commands sent to the industrial equipment during the entropy testing. The device receives packets that were generated during the entropy testing of the industrial equipment and include sensor data regarding the physical process. The device determines whether the sensor data is inconsistent by analyzing the sensor data using a machine learning model that models the physical process. The device initiates a corrective measure, when the sensor data is determined to be inconsistent.

Abstract: Presented herein are techniques for assigning Ultra-Wideband (UWB) anchors for client ranging. A location server can estimate a coarse location of a mobile device using a localization technique other than a UWB localization technique. The localization technique can involve multiple wireless access points or other radio devices. The location server can define an area around the coarse location to identify a set of candidate anchors for UWB ranging. The set of candidate anchors can be disposed within the area and include at least a subset of the radio devices. The location server can modify the set of candidate anchors to create a modified set of candidate anchors that includes only UWB-enabled devices. The location server can select a primary anchor from the modified set of candidate anchors and send a command to cause a UWB ranging procedure to be initiated between the primary anchor and the mobile device.

Abstract: Presented herein are infrastructure triggering techniques for secure Ultra-Wideband (UWB) ranging. In one example, a method may include providing UWB ranging parameters to a mobile device via a first radio communication, wherein the first radio communication is a non-UWB radio communication; and triggering the mobile device to perform UWB ranging with a UWB anchor, wherein the triggering is performed using a second radio communication. In another example, a method may include, obtaining, by a mobile device, UWB ranging parameters for a geographic area; obtaining a UWB ranging instruction for the geographic area; and performing UWB ranging with a target UWB anchor based on the UWB ranging parameters and the UWB ranging instruction.

Abstract: The present technology provides a system and method for automating on-boarding and management of IoT devices on data network. The disclosed technology further provides an interactive representation of various performance attribute with automatically generated actionable alert based on operator defined rules and performance-specific threshold values. Furthermore, disclosed technology provides for single-click activation of suggested actions at scale directed at once to all device units within one or more device groups reported in critical state. In this way the proposed technology enables rapid restoration of a network state. Offending device(s) may then be easily identified, from device units within the device category isolated in a resolution space, and managed according to one or more device-specific actionable alerts automatically generated on the offending device.

Abstract: Virtual reality for network configuration may be provided. First, topology data corresponding to a network may be received. Next, a Virtual Reality (VR) representation of the network may be displayed on a VR user interface device based on the received topology data. Changes to the network may be received from a user through the VR user interface device. Effects on behavior of the network that would result in response to the received changes may then be displayed in the VR representation of the network on the VR user interface device.

Abstract: Handoff assistance across multiple radio access technologies can be provided by identifying a first Qualitative Level of Service (QLoS) of a first network that a User Equipment (UE) is connected to for data transmission; identifying a second QLoS of a second network that the UE is not connected to for data transmission; and in response to determining that a difference between the first QLoS and the second QLoS satisfies a handoff threshold, requesting a first access point in the first network to initiate handoff of the UE to a second access point in the second network or recommending from the first access point to the UE to request such a handoff, wherein handoff disconnects the UE from the first network for data transmission and connects the UE to the second network for data transmission.

Abstract: Systems, methods, and computer-readable media for the secure creation of application containers for 5G slices. A MEC application in a MEC layer of a 5G network can be associated with a specific network slice of the 5G network. A backhaul routing policy for the MEC application can be defined based on the association of the MEC application with the specific network slice of the 5G network. Further, a SID for the MEC application that associates the MEC application with a segment routing tunnel through a backhaul of the 5G network can be generated. A MEC layer access policy for the MEC application can be defined based on the SID for the MEC application. As follows, access to the MEC application through the 5G network can be controlled based on both the backhaul routing policy for the MEC application and the MEC layer access policy for the application.
