But George :-) answer my question: Are you running G mode on towers with multiple broadcasts? Like a tower with 3 120* sectors?

Seems when I've seen high powered B ap's in the mix there can be issues. Where as when I see only low powered G things still work. The area I cover is fairly small, so i'm getting densly built out with omni's and sectors all over the place. Mac Dearman wrote: > How are y'all running "G" in so many places?
