The WiGig specification allows devices to communicate without wires at multi-gigabit speeds. It enables high performance wireless data, display and audio applications that supplement the capabilities of previous wireless LAN devices. WiGig tri-band enabled devices, which operate in the 2.4, 5 and 60 GHz bands, deliver data transfer rates up to 7 Gbit/s, about as fast as an 8 antenna 802.11ac transmission, and nearly 50 times faster than the highest 802.11n rate, while maintaining compatibility with existing Wi-Fi devices.
Something, anything other than the Marvell Wireless chipset ... It's not officially confirmed yet but I think if they had switched from the much maligned Marvell Wireless chipset they would have at least mentioned it for a token gratuitous cheer.
