p.s. 802.11ac definitely provides more throughput!

Was this the reason some more space in the 5GHz band was being opened up.. to support the wider channels?

There are many reasons that the 5 GHz space is being opened up. We're fortunate to have had a forward-thinking commissioner in Julius Genachowski who saw the promise of unlicensed technology in general, and 802.11ac in particular. I asked him to write the forward to my 802.11ac book, and the themes of his foreword should be familiar to anybody who's been following his (and to a much lesser extent, my) work for a while. Rules should be loose enough to enable innovation, and support more efficient use of spectrum.

There are two blog posts on the Aerohive blog that are worth reading. My first reaction to the proposal came in January of this year: http://blogs.aerohive.com/blog/the-wi..., and I was interviewed by Network World's John Cox shortly afterward: http://www.networkworld.com/news/2013...

When the proposed rules came out, I read through them, and was pleasantly surprised to see that the FCC requested information on how 802.11ac might be implemented in new spectrum, and what kinds of rules they should consider. They even went so far as to ask whether DFS-type rules were hindering adoption of new technology. At the end of the report, there are statements from the commissioners; Chairman Genachowski refers to Wi-Fi 17 times in his 2-page statement.

For a more detailed look at the rules, see my March blog post on the subject for Aerohive: http://blogs.aerohive.com/blog/the-wi...
