1. A method of operating a wireless access point, the method comprising:
monitoring, on a channel in a radio-frequency band, for interference activity over first and second time periods while operating on the channel;
gathering interference activity data for the channel at sub-intervals of the first and second time periods at least in part by determining, for each sub-interval in the sub-intervals of the first time period, an interference hit value indicative of the interference activity being present or absent;
determining a first interference hit rate value by summing the interference hit values for the sub-intervals of the first time period;
determining a second interference hit rate value based on additional interference hit values for the sub-intervals of the second time period;
aggregating the first interference hit rate value and the second interference hit rate value to obtain an aggregate channel hit rate value;
maintaining historical interference activity information for the channel by storing the aggregate channel hit rate value; and
performing a channel selection operation based at least in part on the stored aggregate channel hit rate value.
