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.

Abstract: 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.

Abstract: Techniques for automated network adjustment are provided. A first data rate currently supported by a first access point is determined, and a second data rate is identified to be evaluated. A first sensor device of a plurality of sensor devices is identified, where a signal strength between the first sensor device and the first access point exceeds a predefined threshold. A first packet error rate is determined for communications between the first sensor device and the first access point using the first data rate, and a second packet error rate is determined for communications between the first sensor device and the first access point using the second data rate. Upon determining that the second packet error rate is lower than the first packet error rate, the first access point is automatically reconfigured to use the second data rate.

Abstract: Techniques for identifying a trusted SSID for a wireless network are disclosed. Prior to establishing a connection with a wireless network comprising a service set identifier (SSID), a network message is received at a wireless station (STA), from an access point (AP) associated with the wireless network. The STA identifies an encrypted identifier in the network message. The STA validates the encrypted identifier, and in response determines that the AP corresponds to a trusted wireless network. The SSID is designated as trusted, at the STA.

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 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: 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.

Abstract: Embodiments herein describe mounting one or more lasers onto an AP to generate a laser pattern on a surface representing the coverage area of an antenna in the AP. In one embodiment, the antenna is a steerable antenna that can be electronically or mechanical steered to point to different directions (without moving the AP as a whole). The laser or lasers can be used to visualize the coverage area of the steerable antenna when pointing in different directions. Advantageously, a technician can use the laser or lasers to identify a location where, if steered, the antenna would provide the desired coverage area. The technician can then steer the antenna to point in that direction to provide the desired radio frequency (RF) coverage.
