## Signal Strength The signal strength is the wireless signal power level received by the wireless client. - Strong signal strength results in more reliable connections and higher speeds. - Signal strength is represented in dBm format (0 to -100). This is the power ratio in decibels (dB) of the measured power referenced to one milliwatt. - The closer the value is to 0, the stronger the signal. For example, -41 dBm is a stronger signal than -61 dBm. ## Noise Level The noise level indicates the amount of background noise in your environment. - If the noise level is too high, it can degrade the strength and performance of your wireless signal. - Noise level is measured in dBm format (0 to -100). This is the power ratio in decibels (dB) of the measured power referenced to one milliwatt. - The closer the value to 0, the greater the noise level. - Negative values indicate less background noise. For example, -96 dBm is a lower noise level than -20 dBm. ## Signal to Noise Ratio The signal-to-noise ratio (SNR) is the ratio between the signal strength and the noise level. - This value is represented in decibels (dB). - In general, your signal-to-noise ratio should be +25 dB or higher. Values lower than +25 dB result in poor performance and speeds. For example: - If you have a -41 dBm signal strength, and a -50 dBm noise level, this results in a poor signal-to-noise ratio of +9 dB. - If you have a -41 dBm signal strength, and a -96 dBm noise level, this results in an excellent signal-to-noise ratio of +55 dB.
