A method (10 or 40) or system (200) of predictive sensing of periodic intermittent interference (PII) can include the measuring (12) of energy on a channel for an indication of PII, determining (14) if a channel is currently in a PII on-cycle, and adjusting (16) a clear channel assessment threshold to a new threshold for improved sensitivity of the PII on-cycle. If a current energy level on the channel is below the new threshold and if a previous on-energy characteristic suggests that the current energy level will remain below the new threshold for a predetermined minimum period of time, then a clear channel indication can be provided (20). A busy channel indication is provided (45) when either the current energy level is above the new threshold or the previous on-energy characteristic suggests the current energy level will not remain below the threshold for predetermined minimum period of time.
