PHY Errors, Noise Floor, Airtime interpretation in ZD
I would like to find out what values for PHY Errors, Noice Floor, Airtime total, busy, RX, TX are good and what values are bad?
If I'm correctly informed, this is what I know:
PHI Errors of < 20000 is acceptable,
Noise Floor above -85 is bad, below -110 is excellent.
Total Airtime 100% would be great since that means the capacity is fully used, total airtime of < 20 could mean there is a lot of interference, or hardly any users.
Is this correct?
What can I learn from the other Airtime values (busy, rx, tx)? Are the values different for 2.4 and 5 GHz? (i.e 2.4GHz NF should be below -90, 5GHz NF should be below -85?)
I'm basically looking for an answer on this question: what values of which fields of the monitoring page in the ZD indicate that an AP is doing great or needs attention?
