Claim Text:
1. A wireless radio system comprising: a radio frequency receiver configured to provide a received signal strength indicator when the wireless radio system is not communicating; and thresholding circuitry configured to: determine a time period when the wireless radio system is not communicating; instruct said radio frequency receiver to provide a received signal strength indicator at a plurality of point in time during the determined time period; generate a bit stream where each bit in the bit stream represents a different point in time of the plurality of points in time; for each of the plurality of points in time, compare the received signal strength indicator to a threshold value representative of radio interference at each of the plurality of points in time; if a received signal strength indicator exceeds a threshold value, set the corresponding bit to the first value; if a received signal strength indicator does not exceed a threshold value, set the corresponding bit to the second value; determine whether a dynamic frequency selection operation is warranted based at least in part on the analysis of a plurality of received signal strength indicators in the bit stream; and transmit a dynamic frequency selection signal indicating whether the dynamic frequency selection operation is warranted based on the determination.
