I have 2 epmp 4500 deployments and I have added screenshots. The first is a epmp4500c with epmp4525 clients, omni split sector mode, and pretty much all of the clients have weaker rssi on rx compared to tx. I chalked it up to the ap being 8x8.
The second deployment is a 4500L, same scenario with the 4525 clients and weak rx compared to tx, 5db in most cases. What was interesting is the legacy clients typically had 2 db better on rx than tx. TX power on the clients was the same accross the 300 and 4000 series clients.
This isn’t entirely atypical, as your EIRP limit on the sector side is much lower than on the CPE side assuming you are operating in unii-1 or unii-3. That said, the antenna characteristics on the sector may make the effect more dramatic if you have CPEs outside of the pattern of the sector, especially vertically.
Another item of note - the 4525 radios tend to run 5db down from both what link planner estimates and what swaps from Force 300 CPEs, at least in reported RSSI. I don’t know if this is a calibration issue, a gui artifact, or real. The modulation rates seem to always be better than expected on the 4k CPEs, even with lower RSSI, so maybe it’s a visual problem.
The tx power is the same on the ap and cpes. Very well could be a visual problem. Just trying to find out what it is. The 300’s don’t have the same problem.
