Samsung X5 Wifi Next Year

Wifi operating in the 60GH/z band and offering a 500% improvement in transfer speeds could be available to users as early as next year.  This x5 improvement is a theoretical figure, and because present day WiFi comes nowhere near its theoretical speed, the real-world improvement of 60GH/z WiFi will more likely be around x10.

Present WiFi operates at 2.4GH/z with some top-of-the-range devices offering the addition of the 5GH/z band (where there's currently mainly completely unused channels available to users, providing they have all the right gear).
