60GHz tech promises wireless docking, USB, HDMI

Every now and again, the rules for how to build a personal computer change. One of those moments may arrive next year with a high-speed wireless technology that could let people link tablets with big-screen TVs or dock laptops when arriving in the office. The technology, which uses the 60GHz band of radio spectrum and is designed to transfer as much as 7 gigabits of data per second, matches what many wired connections provide, either inside a computer chassis or through the profusion of ports that perforate laptop sides. A group called the WiGig Alliance is developing it, and the group announced today new specifications that could help replace the current tangle of cables.
