Abstract: A method for determining presence of a radar includes receiving a plurality of bursts in a dynamic frequency selection (DFS) channel of an access point, storing the plurality of bursts in a queue, in response to the queue comprising a threshold amount of bursts, determining a timespan of a first burst in the queue to a last burst in the queue, partitioning the timespan into at least a first group and a second group, determining a first number of bursts present in the first group and a second number of bursts present in the second group, in response to a difference between the first number of bursts and the second number of bursts equaling more than one, determining the radar is not present, and in response to the difference between the first number of bursts and the second number of bursts equaling one or less, determining radar is present.

Abstract: A method for improving dynamic frequency selection (DFS) includes receiving, by an access point, a plurality of pulses in a DFS channel of the access point, determining, by the access point, a plurality of characteristics of the plurality of pulses, varying, by the access point, a threshold for radar detection, and determining, by the access point and based on at least one of the plurality of characteristics, whether the plurality of pulses are radar.
