R300 APs use Vertical polarization and 2x2:2 radio chains:streams, thru adaptive multiple antenna arrays with BeamFlex active client tracking for best transmit/receive, and not wasting energy elsewhere, for better performance even in high density. The multiple antennas in the arrays allow for better MIMO from reflection.
How you mount the AP will affect your coverage pattern. Or do you have a more specific question?
Thanks for your response. I just didnt know how the coverage was being broadcast out. This kinda helps because we are looking at putting in a couple of ap's in a users home so we were wondering how many. But since its using vertical polarization this helps.
