802.11n is the equivalent of the old days where you'd combine 2 dial-up 
modems into a bigger pipe.  It uses a MIMO (multiple-in-multiple-out) 
technology utilizing multiple radio's and antennas to achieve more 
throughput.  I think it's a dirty hack especially if you've already 
constructed a network that efficiently uses all available spectrum 
already.  Personally, I think it's a cheap way out of actual innovation 
to achieve higher speeds :)
