According to one aspect, a method includes establishing, by an access point (AP), a wireless communications link between the AP and a wireless station, wherein establishing the wireless communications link includes receiving a protected association request frame from the wireless station. The protected association request frame includes rotation pace preference information for randomized Media Access Control (MAC) address rotation management that indicates a preferred rotation pace. The method also includes selecting, by the AP, an Enhanced Data Privacy (EDP) group based on the rotation pace preference, the selected EDP group associated with epoch timing information for rotating wireless frame anonymization parameters at epoch transitions. A response frame that indicates the selected EDP group is transmitted to the wireless station. The AP maintains the wireless communications link with the wireless station based in part on the timing information for randomized M A C address rotation for the selected EDP group.

A Central Network Controller (CNC) of a Time Sensitive Network (TSN) may determine that a data path to a client device comprises a wireless link. The CNC of the TSN may generate a proposed transmission schedule for the time sensitive traffic to the client device through the wireless link in response to determining that the data path to the client device comprises the wireless link. The CNC may provide the proposed transmission schedule to a Wireless Network Controller (WLC) of the wireless link. The CNC may receive a confirmation from the WLC that the proposed transmission schedule can be met. The proposed transmission schedule may be configured in response to receiving the confirmation.

Various embodiments herein disclose coordinating neighbor discovery between access points (APs) with auxiliary radios and APs without auxiliary radios. A corresponding wireless controller comprises a processor and a memory storing instructions that, when executed, cause the controller to perform operations. The operations comprise grouping APs into a first group of more flexible APs and a second group of less flexible APs and querying the second group of APs for a corresponding broadcast interval. The operations further comprise identifying when the second group of APs is scheduled to broadcast parameters, and a broadcast interval for each of the second group of APs and generating a schedule based on the scheduled broadcast and the broadcast interval for each of the second group of APs. The operations additionally comprise providing the generated schedule to the first group of APs and the second group of APs.

Secure device location sharing may be provided. Over a secured link, an indication that a peer-to-peer device desires Automated Frequency Coordination (AFC) based location sharing may be received. Then, from the peer-to-peer device over the secured link, an identity provider (IdP) may be received for the peer-to-peer device. Next, validation of the peer-to-peer device may be requested from the IdP. From the IdP in response to requesting validation of the peer-to-peer device from the IdP, authentication for the peer-to-peer device and an indication that the peer-to-peer device needs AFC based location sharing may be received. An indication that the peer-to-peer device is approved for AFC based location sharing may then be sent to the peer-to-peer device over the secured link.

Secure device location sharing

Wireless dynamic file exchange is provided by, in response to a triggering network condition occurring, initiating an exchange of a parameter file including non-layer two content via a 802.11 message, such as a Generic Advertisement Service (GAS) message between an access point (AP) and a station (STA) connected to the AP; and in response to determining that the exchange was unsuccessful, terminating a connection between the AP and the STA. The parameter file may be sent over several messages and update the parameters for a new session or an existing session. Devices that do not conform to the updated parameters may be disassociated from the AP and re-connect to receive and implement the updated parameters.
