Abstract: The present disclosure describes a network and a method of operating the network. The method includes determining that a portion of a first channel of a first access point overlaps a portion of a second channel of a second access point and in response to determining that the portion of the first channel overlaps the portion of the second channel, adjusting the first access point so that the first access point refrains from transmitting using frequencies in the portion of the first channel that the second access point uses to transmit pilot tones in the portion of the second channel.

Abstract: A preemption service in a wireless network is described. The preemption network increases the reliability of preemption traffic to be quickly delivered over the wireless network. The active preemption service in wireless networks causes the devices in a wireless network to enter a low transmit power state where every device transmits at a power lower than a high or maximum transmission power. Preemption traffic is transmitted from authorized devices at a high or maximum power, over the lower power transmissions, in order to provide an increased guarantee that the preemption traffic will arrive at the intended recipient.

Abstract: Techniques for improved mobility support in wireless networks are provided. A first beacon from a first wireless AP is received, where the first beacon comprises a network identifier (NID) and a service set identifier (SSID). A client device associates to the first wireless AP. Based on the NID, a set of services supported by the first wireless AP are determined. A second beacon is received from a second wireless AP, where the second beacon comprises the first NID, and the client device associates to the second wireless AP based on determining, based on the NID, that the second wireless AP supports the set of services.

Abstract: Techniques for classification of wireless signals are disclosed. These techniques include receiving data describing radio frequency characteristics of a wireless network transmission environment and presenting the data for display on a graphical user interface (GUI) associated with a network device in the wireless network. The techniques further include receiving input from the GUI identifying one or more portions of the data, and training a machine learning (ML) model to classify an interferer in the wireless network transmission environment based on the identified one or more portions of the data.

Abstract: 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.

Abstract: Techniques for managing communications between access points (APs) and stations (STAs) are described herein. In one embodiment, an AP broadcasts a trigger message to a plurality of STAs, the trigger message including a matrix defining a plurality of resource units (RUs) that the plurality of STAs are assigned to transmit or receive data, and a fragment flag. The presence of the fragment flag, within the scheduling matrix, informs the AP that the data transmission that the fragment flag is appended to is a partial transmission that will be completed in a subsequent transmission opportunity.

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: Techniques for peer-to-peer (P2P) transmission in a multi-user (MU) multiple-input-multiple-output (MIMO) environment. A first wireless station (STA), including a plurality of radio antennas, identifies channel state information (CSI) relating to a connection between the first STA and a wireless access point (AP). The first STA determines connection information relating to a MU MIMO P2P connection between the first STA and a second STA. The first STA generates a plurality of values relating to precoding for the plurality of radio antennas, based on the CSI and the connection information. The first STA and the second STA exchange data over the P2P connection, using the plurality of values relating to precoding.

Abstract: Techniques for dynamic prioritization of presenting devices in wireless deployments are provided. Data relating to a transmission between a first device and a second device is received, and the first device is classified as a presenting device for the transmission based on the data relating to the transmission. An access point (AP) providing connectivity to the first device is identified, and the AP is configured to prioritize traffic transmitted from the first device responsive to classifying the first device as the presenting device.

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.
