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.

A phase adjustment is performed on the adjusted combined signal based on amplitude values of the adjusted combined signal during a period of time and an amplitude value of the first signal during the period of time. The phase-adjusted signal is subtracted from the first signal to generate a noise reference signal. The noise reference signal is subtracted from the combined signal to generate a filtered output signal.

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.
