We’re using 3GHz gear with a 3rd party RRU. The cnRanger 201SM is on 2.1.0.0-r3.
Customer is complaining of intermittent connectivity, but has a -95/-100 RSRP and SINR 25/23.
We are seeing the Downlink MCS fluctuate between 0 and about 17, while the Uplink MCS is steady at 22. This corresponds with the history in cnMaestro.
I see the session Count increases, but the Session Uptime does not seem to reset.
The logs show this information…Any clues from the community? Thanks!
