How to Calculate Signal to Noise Ratio

How to Calculate Signal to Noise Ratio

Signal-to-noise ratio = signal strength - noise floor. Use cloudnet APP and other wifi detection tools to detect signal strength; view the AP and radio information connected to the terminal through display wlan client; view the noise floor information of different radio frequency ports through [AP-probe]display ar5drv x calibration in the probe view of the AP. The signal-to-noise ratio can be improved by increasing the signal strength (properly increasing the AP power, etc.) and reducing the background noise. The method of reducing the noise floor: configure option channel-reuse-optimization enable level x in the radio view, and it is recommended to set it to 6. Properly reducing the value can reduce the noise floor value.
