Abstract: Methods and a system described herein manage the power of IoTs and smart devices operating on a wireless network. When an access point coupled to the network receives a low power indication from a battery-powered IoT or smart device, it may take several actions in response. In one case, it extends the target wake time to become longer and longer to preserve the device's battery. In addition, the device changes its operation to conserve power. In another case, it provides power over the wireless network to the wireless device. The access point restores the target wake time when the device returns to a power-ok condition. The device resumes operation according to the parameters in effect before the low power condition occurs.

Abstract: Techniques and apparatus for determining quality of experience (QoE) for wireless communications are described. One technique involves transmitting a QoE support message to an access point (AP) within an access network. The QoE support message queries whether the AP supports providing key performance indicators (KPI(s)) indicative of QoE provided by the access network. An indication of whether the AP supports providing the KPI(s) is received in response to the QoE support message. The KPI(s) are received when the AP supports providing the KPI(s). A determination is made whether to communicate with the AP based at least in part on the KPI(s). Communications are then performed in accordance with the determination.

Abstract: Techniques for wireless network management are provided. A set of characteristics data for a plurality of different wireless networks in a common physical space is collected, and it is determined, based on the set of characteristics data, that the plurality of wireless networks are experiencing spectrum contention. A set of radio frequency (RF) parameter modifications is generated based on the set of characteristics data, and one or more of the plurality of wireless networks are instructed to implement the set of RF parameter modifications. A second set of characteristics data is collected for the plurality of wireless networks.

Abstract: Federated multi-access edge computing availability notifications may be provided by: transmitting, from a User Equipment (UE) to an Access Point (AP) of a wireless network, an attach request for the wireless network that includes authentication credentials for an identity provider independent from the wireless network to authenticate the UE to the wireless network; receiving, at the UE via the AP, an authentication success message for the wireless network from the independent identity provider; transmitting, from the UE to the AP, a Multi-access Edge Computing (MEC) query; and receiving, at the UE from the AP, a MEC response that identifies MEC resources that are available to the UE based on an identity for the UE confirmed by the identity provider to the wireless network.

Abstract: Embodiments herein describe disconnecting, by an access node, a first device having a first media access control (MAC) address due to a network violation and receiving, by the access node, information about a second device having a second MAC address different from the first MAC address. In one embodiment, the information is generated by a certificate server based on a token generated by the second device. Further, when the access node determines, based on the information, that the second device is the first device, the access node denies a connection request from the second device.

Abstract: Aspects described herein include a method and related network device and computer program product. The method includes receiving a neighbor report that indicates whether a first network device in an environment is advertising broadcast services and generating, using the neighbor report, a broadcast optimization map that indicates a set of network devices in the environment that will provide a broadest coverage of broadcast services within the environment. The set corresponds to a minimum count of network devices that supports all current broadcast streams by one or more client devices in the environment.

Abstract: Coordinated radio fine time measurement is provided via sending, from a client device, a ranging request to a first radio; receiving a first response sent at a first time from the first radio over a first channel; receiving a second response sent at the first time from a second radio over a second channel; and calculating, based on times of flight for the first response and the second response, a location of the client device relative to the first radio and to the second radio. Coordinated radio fine time measurement is also proved via in response to receiving, at an Access Point (AP), a ranging request from a client device and determining to respond using multiple channels: sending, both at a first time, a first response from a first radio over a first channel a second response from a second radio over a different channel.

Abstract: Techniques for improved wireless ranging are provided. A first communication from a first client device is received at a first network device. A predefined minimum distance is determined for the first access point, where the predefined minimum distance corresponds to a distance at which the vertical location of the first network device causes time of flight ranging techniques to result in inaccurate location estimations. A first distance of the first client device from the first network device is estimated. Upon determining that the first distance of the first client device is below the predefined minimum distance, ToF ranging requests from the first client device are declined.

Abstract: Techniques for policy exchange are provided. A wireless local area network (WLAN) system configures a first policy to apply to devices connecting to the WLAN system, where the first policy is associated with a first event context. The WLAN system then transmits, to a cellular system, the first event context and an indication of the first policy. The WLAN system further receives a first connection from a first user equipment (UE). Finally, The WLAN system transmits a first response to the first UE specifying the first event context, where the cellular system, upon receiving the first event context from the first UE, identifies and applies the first policy based on the first event context.

Abstract: Techniques for enhancing the security of network access within an open roaming framework are provided. A first network device receives a request to authenticate connection of a user device to a network. The first network device retrieves security data associated with the network. Based on analyzing the security data associated with the network, the first network device determines that one or more security criteria are satisfied. The first network device transmits a response to the user device, where the response instructs the user device to establish a connection with the network and does not disclose the security data.
