Can somebody give me recommendations on what I should use for blanket wireless access for multiple condo unit building 4 stories high? I was looking to use the 1300 series and possibly the Air ANT24120 antenna. I want it to penetrate through walls a floors. If anybody has any past experience on this, could you recommend this or another product? Also I am looking to see how far the signal can carry. I am trying to cut down on AP's.
