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 identifying a trusted SSID for a wireless network are disclosed. Prior to establishing a connection with a wireless network comprising a service set identifier (SSID), a network message is received at a wireless station (STA), from an access point (AP) associated with the wireless network. The STA identifies an encrypted identifier in the network message. The STA validates the encrypted identifier, and in response determines that the AP corresponds to a trusted wireless network. The SSID is designated as trusted, at the STA.

Abstract: Techniques for routing data in a wireless communication network including a hybrid of infrastructure wireless local area network (WLAN) and neighbor awareness networking (NAN). A subscription is identified between a first NAN device in a first NAN cluster in the network and a second NAN device in a second NAN cluster in the network. The first NAN cluster includes at least one NAN device not included in the second NAN cluster. A first path is generated between the first NAN device and the second NAN device. The first path includes a first network access point (AP) in the network. Data is transmitted from the first NAN device to the second NAN device using the first path comprising the first AP.

Abstract: A machine learning based adaptive short beacon activation (SBA) engine is described. The SBA engine provides for activating or suppressing short beacon transmission in a network cell based on total network cell effects in both airtime consumption and network flows as determined by the SBA engine. In some examples the SBA engine utilizes input parameters received from various wireless medium to evaluate the current and near future advantages and/or disadvantages of activating/suppressing short beacons.

Abstract: Various embodiments herein disclose scheduling relay of traffic. The method comprises, selecting a second client device from a plurality of client devices. The second client device is located in communication range of the first client device. The first client device is communicating a first portion of a data flow, via a first wireless link, with a first access point of the one or more access points. The method comprises, in response to determining satisfaction of one or more relay criteria: directing the first access point to generate a second wireless link with the second client device; and directing the first access point to provide first metadata including a first set of relay instructions. The first set of relay instructions instructs the second client device to relay a second portion of the data flow between the first access point and the first client device via the second wireless link.

Abstract: Embodiments for selective optimized roaming include receiving an indication that a connected device is at a cell edge of a first network. When an alternate access point cannot provide an alternate connection for the connected device, connections to other networks are assessed. This assessment includes receiving radio frequency (RF) signals for a second network and determining, from received RF signals, that the second network provides a better network connection. When the second network can provide a better network connection the connection to the first network is terminated.

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.

Abstract: The present disclosure provides techniques for handling MAC address collision within an ESS comprising at least one wireless station and at least one access point (AP). An AP receives a first IRM address during execution of a handshake protocol between the AP and a wireless station. The AP determines that the first IRM address is allocated for use by another wireless station and then transmits a message to the wireless station. The AP receives a first wireless action frame transmitted by the wireless station after execution of the handshake protocol, where the wireless action frame includes a second IRM address selected by the wireless station. The AP establishes a wireless connection with the wireless station in a subsequent association with the wireless station using the second IRM.

Abstract: The present disclosure describes systems and methods for negotiating power harvesting. An access point includes a memory and a processor communicatively coupled to the memory. The processor receives, from a first device, a first message indicating a first amount of power harvested by the first device and a second amount of power requested by the first device and determines, based on the first amount of power, that transmitting a third amount of power will cause the first device to receive the second amount of power. The processor also transmits the third amount of power.

Abstract: Disclosed are a system and method for avoiding interference in direct communication between peers in a Wi-Fi network. A station (STA) desiring to communicate directly with another STA reports a change in interference to a function that determines a set of unsafe frequencies caused by interference near the STA. The function sends a report containing the set of unsafe frequencies to the AP for the STA. The AP then evaluates the severity of the interference and selects a set of RUs that are suitable for a TXOP for direct communication between the STA and another STA. The AP informs the STAs of the selected set of RUs, and the STAs communicate with each other using the selected RUs. If allowed, the STA sends feedback regarding the success of the communication to the AP.
