Abstract: Technologies directed to Dynamic Frequency Selection (DFS) channel assessment mechanisms are described. A processing device of a first wireless device identifies a channel identifier corresponding to a first operating channel being used by a first radio of the first wireless device to communicate with a first access point (AP) enabled on a radio of a second wireless device. The processing device identifies multiple devices in proximity to the first wireless device using a second radio. The processing device determines an airtime utilization percentage value for each operating channel of the second radio and determines a number of radar events for each DFS channel. The processing device determines a second channel identifier having a fewest number of radar events and selects a second operating channel for a second AP on the second radio, the second channel corresponding to the second operating channel.
