I just checked our other 900 OFDM AP's and there is more activity on the "Reg" column. So if the Re-Reg Quality Index only looks at the "Re-Reg" column, I don't believe it's a good indicator. Having both wont hurt if they can fit, but the same data is just two tabs over in "Session".
How often does the Quality Index + LQI get calculated?
How to use 900MHz spectrum? Is that unlicensed for all? What's the procedure if I want to use 902-928MHz? I'm the freshman on radio and I will more than happy if I can get any useful knowlege from your case.
