I'm glad someone at least seems to be addressing congestion. Every 802.11 standard seems to have hopped on the "multiple bandwidth by 2x" bandwagon, which is great if I live in a single family house with tons of space. I don't, I live in a city, in an apartment building, surrounded by apartment buildings. I can frequently see 30+ networks. I'm sure there are wireless phones and other devices crowding the spectrum as well. Give me more channels, or better ways to share spectrum, anything other than dividing the number of usable channels with every update.

It might use 2x the bandwidth, but it will use it for half the time for the same amount of data, so it all evens out (almost; there's an unused "border" between channels, so 2x the bandwidth is a bit more than 2x faster, and it will use a bit less than half the time). And the 802.11ac standard has a way to better share the wide channels and the narrow channels; see the "Dynamic Bandwidth Operation" chapter of the "802.11ac: A Survival Guide" book at http://chimera.labs.oreilly.com/books/1234000001739/ch03.html#section-mac-dynbw http://chimera.labs.oreilly.com/books/1234000001739/ch03.htm...
