摘要： Techniques for wireless multi-link operation (MLO) are disclosed. These techniques include determining that a first wireless station (STA), in a wireless network comprising a wireless access point (AP) and a plurality of peer-to-peer (P2P) STAs, comprises a non-simultaneous transmit and receive (NSTR) constraint. The techniques further include allocating one or more wireless links relating to MLO for the AP and the plurality of P2P STAs, based on the NSTR constraint, and initiating transmission between the AP and one or more of the P2P STAs using MLO and the allocated one or more wireless links.

摘要： Techniques for wireless communication are disclosed. These techniques include determining that a first wireless access point (AP) has a failure to connect to a controller. The techniques further include identifying one or more neighbor APs, for the first AP, as candidate rescue APs, selecting a rescue AP, from among the candidate rescue APs, and establishing a secure connection from the first AP to the rescue AP. The techniques further includes transmitting diagnostic data from the first AP to the controller using the secure connection from the first AP to the rescue AP. The diagnostic data relates to the failure to connect from the first AP to the controller, and the controller is configured to use the diagnostic data to assist in establishing a connection from the first AP to the controller that bypasses the rescue AP

摘要： Techniques for sounding for wireless communication are disclosed. These techniques include initiating staggered sounding between a plurality of wireless access points (APs) and a plurality of wireless stations (STAs), including transmitting, from each AP of the plurality of APs, a sounding trigger to a respective one or more of the plurality of STAs, where the sounding triggers are transmitted by the respective APs at staggered times. The techniques further include receiving sounding matrix data at the plurality of APs from the plurality of STA. The techniques further include modifying wireless transmission between at least one of the APs and at least one of the STAs based on the sounding matrix data.

摘要： Dynamic automatic gain controller configuration in multiple input and multiple output receivers is provided by monitoring a given section of wireless spectrum for higher-priority signals using a first antenna set associated with a first Automatic Gain Controller (AGC) set while concurrently monitoring the given section of wireless spectrum for wireless packet-based traffic using a second antenna set associated with a second AGC set; in response to detecting a packet via the second antenna set: re-associating the first antenna set and the second antenna set to a third AGC set; receiving the packet via the first antenna set and the second antenna set using the third AGC set; and in response to the packet being received, re-associating the first antenna set to the first AGC set and the second antenna set to the second AGC set.

摘要： An electronically a steerable and switchable antenna array is provided that can produce a first beam with a first coverage range and a second beam with a second coverage range by selecting one of a first and a second beamwidth for both the first and second beams; in response to selecting the first beamwidth: switching signal inputs to narrow-beam antenna arrays; steering the first beam to one of a first positive, negative, or zero offset position; independently steering the second beam to one of a second positive, negative offset, or zero offset position; and transmitting signals received from the signal inputs via the first beam and the second beam; and in response to selecting the second beamwidth: switching signal inputs to wide-beam antenna arrays; and transmitting signals received from the signal inputs via the first beam and the second beam.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： Techniques for identifying a trusted SSID for a wireless network are disclosed. Prior to establishing a connection with a wireless network, a first network message is received from a first access point (AP) identifying a first service set identifier (SSID) associated with a first wireless network, a second network message is received from a second AP identifying a second SSID associated with a second wireless network, and a visual similarity is determined between a first visual representation of the first SSID and a second visual representation of the second SSID. The second SSID is designated as suspicious based on the determined visual similarity.
