Meaning of 5G n-1 in AP Logs

[Highwater_Pants]

Hello Experts.

Does anyone here know what does 5G n-1 mean ?

SignalStrengthMonitor:2: isAboveEntryThreshold 5G n-1: cell info ssRsrp

I see it printed on ap logs from time to time.

Usually instead of n-1 it should show the actual band like n48 or n71 etc, but somehow I am seeing a few prints of n-1 which I can’t find any material online.
