What is hcxPortPrevMeanNoise?
This read-only Integer32 reports the mean noise level, in dBmV, sampled during the previous, completed 15-minute period, per the description. It gives the admin a finalized noise-floor data point suitable for historical trending or comparing against the current period's value. For example, comparing hcxPortPrevMeanNoise to the live hcxPortCurrMeanNoise value tells the admin whether noise is worsening or improving interval over interval.
