Please check me on this

We have all of our APs in our network set to 6 miles. They are 900 MHz and because of the terrain, there is little reason to extend them farther. However, I have one AP I would like to extend out to 9 miles. Using the Frame Rate Calculator, I have found that by changing the down link percentage from 75% to 77%, the and of course the miles from 6 to 9, I get exactly the same Uplink Rcv SQ Start of 11531. So… I should be able to make this change with out any negative effect of the network. Right? I want to check myself here before I put a single customer on that is beyond 6 miles.

Interesting question. I cannot answer but I’m looking forward to reading the answer from somebody.
