When will people learn that wifi isn't meant for a MAN. 100 feet max using any stock laptop. Plus competing with all the other 2.4 interference. Anyone wanting to set up a wifi mesh/gird/wide area coverage should only use »en.wikipedia.org/wiki/IEEE_802.11y and not pollute 2.4 even more. And you wonder why there isn't ubiquitous wifi coverage and cellular standards won.
1.) The standard was just ratified 6 months ago 2.) The frequency is higher so penetration and range will be lower 3.) Show me a laptop or phone with built-in 802.11y 4.) It's a LICENSED spectrum
