alphadogg writes "Mobile devices like the iPhone 5 are embracing the 5GHz band, and that trend will expand as 802.11ac radios become prevalent even on smartphones starting in 2013. The FCC announced a New Year's Wi-Fi gift during the International CES show earlier this month: a proposal to dramatically expand the unlicensed spectrum in the 5GHz frequency band for use by Wi-Fi devices. The announcement comes as a growing number of vendors are announcing products that will support the "Gigabit Wi-Fi" 802.11ac standard in 2013. To find out the implications of the FCC's plan, Network World talked with Matthew Gast, director of product management for Aerohive Networks (author of "802.11n: A Survival Guide"). Gast blogged enthusiastically after FCC Chairman Julius Genachowski announced the spectrum move, even admitting he had an 'engineer-crush' on the chairman as a result."
