A wireless system includes memory configured to store information of physical layer rates associated with power levels between a client device and respective access points. The power levels comprise information of amounts of power in signals received by the client device from the respective access points. The system includes one or more processors configured to: during a communication session between the client device and a first access point, determine a current power level between the client device and a second access point, access the information based on the current power level to determine an expected physical layer rate between the client device and the second access point, determine a current physical layer rate between the client device and the first access point, and determine whether to switch the communication session to the second access point based on the expected physical layer rate and the current physical layer rate.

Physical layer rate estimates in wireless communication systems

A system for interference detection includes one or more processors are configured to receive from one or more access points within a wireless network information indicative of airtime usage of one or more client devices associated with the one or more access points, determine an amount of total interference for at least one of the access points on a first channel, the total interference including foreign interference and in-network interference, determine a correlation between the total interference and the airtime usage of the one or more client devices, determine an amount of the foreign interference or an amount of the in-network interference based on the correlation, and selectively switch the at least one of the access points from communicating on the first channel to communicating on a second channel based on the determined amount of the foreign interference or the determined amount of the in-network interference.

In-network wireless interference detection

Systems and techniques for increasing wireless network performance using contextual fingerprinting are described herein. Performance metrics may be obtained for a client device-access radio pair that includes a wireless network interface of a client device and an access radio of a wireless network associated with the client device. A fingerprint may be generated for the client device-access radio pair. The fingerprint may be stored in a fingerprint store for the wireless network.

Increasing wireless network performance using contextual fingerprinting

Footwear having interchangeable heels, includes: (a) a top component having a back section, a middle, a front and an upper section for encompassing a foot, the top component having an underside shape and contour, and having at least two separate connect mechanisms for connection to a bottom component; (b) a bottom component having a having back, a middle, and a front section, the bottom component having a topside shape and contour sufficiently coinciding with the top component underside shape and contour so as to nest with one another, and having at least two separate connect mechanisms corresponding to the at least two separate mechanisms of the top component for connection to it; and (c) at least one locking mechanism.
