I have a customer who have done a 1-to-1 swap from MSM422 APs to IAP-205, and are now complaining that they lack radio coverage in some areas where they used to have coverage.
I assume they are talking about 2.4Ghz coverage as we talking about the edge of the coverage of both systems.
My question is: Did the MSM422 actually have better internal antennas than the IAP-205, so they can't really expect the same coverage?
Or, is the IAP just by default reducing its TX power to better optimize for many "weak clients" that can't hear each other?
I don't know what TX power level the old MSM422 was running at, but the new IAP's are default configured and have selected 19 dB on 2.4Ghz and 21 dB on 5Ghz.
If the IAP-205 actually do have physically worse antennas than the MSM422, are there other Aruba APs that would better match the performace of the MSM422 from a pure antenna gain perspective? Any comparation guide available that compare the different APs from this perspective?
