Gigabit Wi-Fi: Difference Engine: Unplugging the cables | The Economist: "Which 60-gigahertz technology will prevail? For consumers, it does not really matter. Suffice it to say that the Wireless Gigabit Alliance (promoter of the WiGig specification) recently merged with the Wi-Fi Alliance, the body responsible for certifying the IEEE’s 802.11 family of wireless standards (“a”, “b”, “g”, “n” and, coming soon, “ac”). In due course, the Wi-Fi Alliance is expected to incorporate WiGig technology in its own “ad” offering. Anticipating such a move, two specialist chipmakers, Marvell and Wilocity, joined forces last year to bring tri-band Wi-Fi devices operating in the 2.4-gigahertz, 5-gigahertz and 60-gigahertz bands to market sometime in 2014."
