Gogo has unrolled a major upgrade to its in-air Wi-Fi access for 2012. Starting with Virgin America, its ATG-4 spec Wi-Fi promises to quadruple the practical speed, enough to where HD video streaming is an option. It upgrades to the faster EVDO Revision B standard for its 3G and also has upgrades to improve the connection quality, such as two modems on the aircraft to reduce bottlenecks and a directional antenna to focus the signal.
