Understanding the RF Score

RF score is a calculated number on a scale of 1-10 that is used to represent the overall condition for a channel. The higher the score, the better the RF environment is. Low scores indicate that attention is needed.

SonicWall wireless drivers report signal strength in RSSI, this number is used in the preliminary RF score equation to get a raw score on a scale of 1 to 100:

rfaScore100 = 100-((rssiTotal-50)*7/10))

Simplified: rfaScore100 = -0.7*rssiTotal + 135;

The final score is based on this rfaScore100:

• If the RFA score is greater than 96, it is reported as 10.
• If the RFA score is less than 15, it is reported as 1.
• All other scores are divided by 10 to make them fall into the 1-10 scale.

In the SonicOS interface, the RF Score is displayed for the channel that is being used by the SonicWall access points.

This feature depends on the knowledge of what channel SonicPoint is operating in. If the channel number is unknown, RF Score is going to be not available.
