Hi community,
From my research, there are 2 ways to measure signal strength:
Different vendor goes with different way to measure signal strength collected by their APs. I think Meraki APs uses RSSI since I saw positive signal strength values in our data.
I saw a document [*] which shows conversion (from RSSI to dBm) for Cisco device as follows:
The above conversion applied when range of RSSI is from 0 - 100.
My question are:
Thank you,
Daniel

Note this special "Meraki" formula:
RSSI - 95 = signal strength in dBm
It's hard to find, but buried deep in this document:

For a bit more information, take a look at this thread: https://community.meraki.com/t5/Wireless-LAN/Displayed-Client-RSSI-equivalent-Client-Band-RSSI-table...
Key point is that Meraki often shows SNR rather than RSSI.
Thanks, 95 stuck in my mind as something familiar.
-95dBm is the starting point for the RX-SOP slider in an RF Profile. I'm guessing -95dBm is also Meraki's min receive sensitivity.
