RF Health Metric
New in Version 3.3.0
New experimental troubleshooting tool: “RF Health” This is a modification of the RF index to change the format to a 0 to 100 metric, the higher the better, for a easier to use experience it should work properly to isolate what areas/Aps of the deployment are having a bad RF state, affecting clients.
RF Health will try to calculate different metrics applicable to RF quality on the AP, and convert to a single 100 based scale. It takes into consideration things like low SNR client count, co-channel interference, channel utilization for nearby Aps, noise, etc. It currently supports 20/40 channel width, and handles properly bonding scenarios. You can open “RF problem finder” to get details on the metric per type, per AP, for in depth analysis Please provide your feedback on the metric, for additional improvements, change on default values, etc.
