A customer has implemented a wireless network that requires tuning for High Density applications utilizing the RX-SOP feature. They are experiencing a high noise floor (average of - 65 dBm) and…

-60 dBm is above the noise floor of -65 dBm, meaning the AP would reject even signals that are stronger than the noise floor, causing legitimate clients with moderate RSSI to be ignored.

-65 dBm matches the current noise floor exactly and does not provide a useful margin above the -75 dBm neighbor signals to begin effective filtering.

Setting RX-SOP to -70 dBm places the threshold above the same-channel neighbor signal level of -75 dBm, which causes the AP to discard those interfering frames since they fall below the threshold. This is a conservative starting value because the noise floor at -65 dBm is expected to improve, and -70 dBm provides a safe working margin without aggressively dropping legitimate client traffic.

-75 dBm is equal to the neighboring AP signal level, so those interfering frames would sit right at the threshold and may still be processed rather than reliably discarded.

-80 dBm is below the neighboring AP signal level of -75 dBm, meaning the co-channel neighbor frames would still be received and processed, providing no interference relief.
