Techniques for classifying RF channels in a first system (e.g., a Bluetooth system) to mitigate the deleterious effects of interference from a second system (e.g., a WLAN system) are described. One or more metrics (e.g., PER and/or RSSI) are determined for the RF channels. Each RF channel may be classified as good or bad based on the metric(s) for that RF channel. Whether excessive interference is observed on any frequency channel for the second system is determined based on the metric(s) for the RF channels. Excessive interference may be declared if the average PER for RF channels overlapping a frequency channel exceeds a threshold THW or if the number of bad RF channels within the frequency channel exceeds a threshold THC. A set of usable RF channels is formed and includes good RF channels not overlapping any frequency channel with excessive interference.
