802.11ac wave 2 doesn't need multigigabit in an enterprise environment. 
I've gone on about this almost a year ago [1], but the short version is 
that real-world performance won't exceed 1Gbps full-duplex, and you're 
better off having many APs than big powerful ones since the high rates are 
extremely distance limited. Worst case you could run two cables, the 
high-end APs all come with two ethernet ports these days.

Now, 802.11ax, or "High Efficiency WLAN" which is learning from the 
lessons of 802.11ac and trying to improve real-world performance 
instead of just the headline numbers, might change things. But that's 
another 2+ years away.
