Abstract: A method includes steering client devices to access points that potentially increase capacity of communications using beamformed transmissions. In particular, this includes determining the best access points for beamforming to a particular client or a group of clients in the network for an improved throughput performance in the deployment or a subset of access points.

Abstract: A method includes determining an optimized channel width between client devices and access points based on network conditions in a wireless network. In particular, the channel widths may be optimized to reduce airtime usage on access points and eliminate a high density condition while the client devices are steered to access points that provide the greatest channel capacity gains based on signal-to-noise-ratios for each spatial stream in a beamformed transmission.

Abstract: Devices, computer-program products, and methods for identifying two or more traffic flows with similar packet traffic characteristics are disclosed. In some implementations, the traffic flows may be transmittable over one or more wireless paths. In these implementations, the method may further include identifying a wireless path along which the two or more traffic flows may be transmitted. In some implementations, the method may further include determining whether the wireless path can implement spatial signal multiplexing. Making this determination may include using sounding information associated with the wireless path. In some implementations, the method may include grouping two or more traffic flows to transmit along the wireless path when the wireless path implements spatial signal multiplexing. In these implementations, the two or more traffic flows may be grouped according to similar packet traffic characteristics.

Abstract: Described herein are systems, methods and computer program products for controlling operation of wireless network devices, such as wireless access points and wireless client devices. The techniques described simplify the process of associating wireless devices with wireless networks. Wireless devices can associate with a wireless access point without knowing details of the wireless access point, such as a service set identifier (SSID). Upon associating with a wireless access point, client devices cease transmission of or reduce a transmission rate of wireless probe requests, resulting in more efficient wireless radio frequency use and reduced possibility of interference due to wireless probe request transmissions.

Abstract: The present disclosure discloses a method and a network device for client association management based on estimated session duration. Specifically, a network device determines that a client device is on an active session. The client device is associated with a first access point of a plurality of access points. The network then estimates a remaining duration of the active session to obtain an estimated remaining duration. Responsive at least to the estimated remaining duration of the active session being greater than a threshold value, the network device causes the client device to associate with a second access point different than the first access point. Responsive at least to the estimated remaining duration of the active session being less than the threshold value, the network device refrains from causing the client device to associate with the second access point.

Abstract: Methods and systems are described for determining an optimal access point for a client device based on the relative difference between signal strengths of wireless signals received by the client device from access points. In particular, the signal strengths of wireless signals received by a client device from access points are determined without receipt of signal strength and/or transmit power information from the client device. Instead, the signal strength difference value may be determined based on known characteristics of signals transmitted by the access points and known characteristics of signals received by the access points from the client device. This relative difference value may thereafter be used to determine an appropriate access point to provide network access to the client device.

The self-interference within a device may be reduced by first transmitting, by a first circuitry, a first set signals using a first radiation pattern through a first set of antennas coupled with the first circuitry. Then, based on feedback information associated with the first set of signals detected by a second circuitry of the device, a second radiation pattern to be used by the first circuitry and the first set of antennas that reduces receipt of signals by the second circuitry that are transmitted by the first set of antennas or leaked from the first circuitry may be determined. Thereafter, a second set of signals may be transmitted by the first set of antennas using the second radiation pattern.

Abstract: The present disclosure discloses a method and network device for software-defined client device management. Specifically, a network device can cause a client device to switch association with a first access point to a second access point. The network device determines whether a number of times the client device has been caused to switch association with an access point exceeds a threshold value for the first period of time. If not, the network device causes the client device to switch to an association with a third access point. Also, the network device determines a configuration indicating when any access point with which a client device is associated may be modified. Based on the configuration, the network device determines whether an association of the client device should not be modified. Also, based on one or more attributes, the network device selectively causes the client device to switch an association.
