Brian, Food for thoughts...
How is the over-subscription to the commodity Internet keeping up with Wi-Fi these days? Most services are in the cloud and it seems that Internet Commodity could be the limiting factor rather than wave1 or wave2 or even staying with 802.11n. Is it worth worrying about 802.11ac wave 1 or wave 2 when your Wi-Fi is so much more capable than your campus uplink? (or is it?) When we talked about 802.11g VS 802.11n there were huge differences between the two. Is it still the case between wave 1 and wave 2? Software support lifecycle seems to be the main determining factor in Wi-Fi infrastructure upgrades. So, rather than Wave1 VS Wave2, we should maybe consider vendors with longer software lifecycle support. Also, many of us upgraded from 802.11n to 802.11ac building-wide and even campus-wide because n and ac didn’t play well together. How do Wave1 and Wave 2 play together?
