A method to operate a multi-link wireless device. The method includes establishing at least a first multi-link device interface and a second multi-link device interface, exposing, via a virtual data port, the first multi-link device interface and the second multi-link device interface at a data processing layer of the wireless device, selecting one of the first multi-link device interface and the second multi-link device interface, as a selected multi-link device interface, based on performance information associated with a first radio and a second radio associated, respectively, with the first multi-link device interface and the second multi-link device interface, and wirelessly transmitting a packet from the wireless device by routing the packet through the selected multi-link device interface.

Backscatter Device (BKD) placement and placement calibration may be provided. A plurality of ambient energy sources in a Three-Dimensional (3D) space may be identified and mapped. Each of the plurality of ambient energy sources may be categorized as one of the following: a stationary and controllable ambient energy source, a stationary and uncontrollable ambient energy source, and a mobile ambient energy source. An amount of ambient energy available at each of a plurality of sub-spaces of the 3D space may be determined. The amount of ambient energy available at each of the plurality of sub-spaces may be determined by determining a first amount of ambient energy that is continuously available and a second amount of ambient energy that is likely available at each of the plurality of sub-spaces of the 3D space.

Backscatter device placement and placement calibration

Correlating devices and clients across addresses may be provided. A first address associated with a client device may be received. When the client device is not connected to a network, first location data associated with the first address may be obtained using a passive technique. A second address and second location data associated with the second address may then be obtained using an active technique. It may then be determined that the first location data and the second location data correlate. In response to determining that the first location data and the second location data correlate, it may be determined that the client device has changed from the first address to the second address.

Correlating devices and clients across addresses

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.

Openroaming augmentation method for EAP failures

Techniques for improved peer-to-peer communication are provided. A roaming peer-to-peer device may identify a new access point (AP) and initiate a transition to the new AP. Initiating transition can involve sending, to the new AP, the current peer-to-peer communication schedule for approval and/or negotiating a modified peer-to-peer communication schedule with the new AP. When the roaming peer-to-peer device and the new AP agree on the peer-to-peer communication schedule, the peer-to-peer device may notify its counterpart that it has roamed to the new AP and also notify the counterpart of any updates to the peer-to-peer communication schedule.

P2P continuity during a client roam

A method is performed at a mesh access point (MAP) of a mesh network in which MAPs are configured to communicate with each other over wireless backhaul links. The method includes: receiving, from a first wireless client having a first client address, client traffic destined for a second wireless client having a second client address, the client traffic including a first source address that represents the first client address, and a first destination address that represents the second client address; generating a first obfuscated source address that differs from the first client address; replacing the first source address in the client traffic with the first obfuscated source address; and transmitting the client traffic with the first obfuscated source address in place of the first source address to a next MAP of the MAPs over a wireless backhaul link for subsequent forwarding to the second wireless client.

Techniques for beamforming from wireless stations (STAs) are disclosed. These techniques include identifying a plurality of STAs for a beamforming group, for transmission to a wireless access point (AP). The techniques further include receiving, at the AP, first data transmitted from each of the plurality of STAs in the beamforming group to the AP at least partially at the same time, wherein the transmitting the first data from each of the plurality of STAs results in constructive interference between the transmissions from the plurality of STAs to the AP, and wherein the same first data is received from each of the plurality of STAs in the beamforming group.

It may be determined that the request does not comprise network characteristics of the application. In response to determining that the request does not comprise the network characteristics of the application, the network characteristics may be requested from a Wireless Local Area Network (WLAN) controller. The network characteristics may be received from the WLAN controller. Schedules for the application may be determined based on the network characteristics. The schedules may be enabled.

Techniques herein facilitate a device address rotation management protocol that may be implemented for a wireless local area network (WLAN), which can be used to influence when wireless client devices or stations may rotate their Media Access Control (MAC) addresses, how to perform such rotations, and/or the like. In one example, a method may include providing, by an access point (AP), a first communication indicating that the AP supports a MAC address rotation management protocol; obtaining, by the AP, a second communication from a wireless station (STA) indicating that the STA intends to perform a MAC address rotation; and transmitting, by the AP, a third communication to influence the MAC address rotation of the STA, the third communication comprising a rotation status indicator and timing information.
