Abstract: Techniques for managing communications between access points and stations (STAs) are described herein. An access point broadcasts a trigger message to a plurality of STAs, the trigger message includes a matrix defining a plurality of resource units (RUs) that the plurality of STAs are assigned to transmit or receive data. The matrix accomplishes time division multiplexing by assigning timeslots to a plurality of STAs. The matrix accomplishes frequency division multiplexing by also assigning frequency tones to the plurality of STAs.

Abstract: In one embodiment, an access point of an overhead mesh of access points in an area selects a range of client identifiers. The access point sends, via a beam cone transmitted in a substantially downward direction towards a floor of the area, a trigger signal that includes the range of client identifiers and prompts client devices having identifiers in that range to send best effort transmissions towards the overhead mesh. The access point detects a collision between the best effort transmissions of the client devices. The access point adjusts the range of client identifiers so as to avoid future collisions between the best effort transmissions of the client devices.

Abstract: Aspects described herein include a method of automated grouping of client devices for a user-defined network (UDN). The method includes receiving, from a client device an authentication request to join an access provider network. The authentication request includes a unique identifier of the client device for a federation-based network. The method further includes transmitting the unique identifier to a UDN cloud, transmitting the authentication request to an identity provider, and receiving, responsive to the identity provider authenticating the authentication request, a list of one or more UDNs from the UDN cloud that are associated with the unique identifier. The method further includes joining the client device with one or more other client devices present on the access provider network listing a same UDN.

Abstract: Wireless planning for reduced power consumption may be provided. Characteristics of a space may be received, wherein the characteristics include a representation of the space. A model of the space may be generated using the representation of the space. Next, a coverage requirement and a power saving requirement may be determined for the space. An initial wireless plan may be generated including one or more APs positioned in the model of the space. The initial wireless plan may be adjusted based on the coverage requirement and the power saving requirement to generate a final wireless plan.

Abstract: Techniques for wireless communication are disclosed. These techniques include defining a message schedule for fine time measurement (FTM) at a first wireless access point (AP). The techniques further include broadcasting the message schedule to a plurality of wireless stations (STAs) from the first AP. The techniques further include receiving, at the first AP, a plurality of FTM messages from the plurality of STAs, the messages transmitted by the plurality of STAs based on the message schedule. The techniques further include determining a distance between the first AP and each of the plurality of STAs based on the plurality of FTM messages.

Abstract: In one embodiment, a mobile node in a wireless network determines a physical location of the mobile node. The mobile node obtains telemetry data. The mobile node makes a comparison between the physical location of the mobile node and a location-based telemetry reporting policy. The mobile node sends, based on the comparison, the telemetry data via the wireless network.

Abstract: In one embodiment, a device registers with a controller for a mesh of overhead access points. The device receives, from the controller, a communication schedule for the device. The device generates a message to be sent to the mesh of overhead access points. The device transmits, according to the communication schedule, the message as a beam cone directed substantially upward relative to the device towards the mesh of overhead access points. The message is received and relayed by one or more particular access points in the mesh without the device previously performing a wireless association exchange with those one or more particular access points.

Abstract: In one embodiment, a controller identifies access points forming an overhead mesh of access points in an area, each access point comprising one or more directional transmitters each configured to transmit a beam cone in a substantially downward direction towards a floor of the area. The controller assigns the access points to access point groups. The controller generates communication schedules for the access points such that each access point in an access point group is on a common channel and only one of neighboring directional transmitters of access points in that group is able to transmit at any given time. The controller sends the communication schedules to the access points forming the overhead mesh of access points in the area.

Abstract: Techniques for detecting and/or confirming a Man-in-The-Middle (MiTM) attack using Fine Timing Measurement (FTM) are provided. In one aspect, a FTM exchange is initiated between a second station and a first station to detect or confirm a MiTM attack in a network in which a MiTM is positioned between the first station and a third station. The MiTM attack is detected or confirmed, or both, based at least in part on FTM information determined during the FTM exchange.

Abstract: In one embodiment, a device determines a physical location of a mobile client of wireless network. The device performs a frequency lookup for the mobile client from an AFC service using the physical location of the mobile client. The device selects a frequency to be used by the mobile client based on the frequency lookup. The device causes the mobile client to use the frequency to communicate with the wireless network.
