Wireless at 60 GHz is a strictly line-of-sight proposition. If pretty much anything gets in the way (especially a water-laden human body, but walls, especially with metal studs, are problematic, too), poof, there goes your signal. Sure, there's some diffuse reflection if you stay in the same room, but once you start relying on that, the power requirement (for given bandwidth) goes WAY up. Looks like bright boys at WiHD are poised to deliver an inherently unreliable technology that will cause consumers anguish as they try to cope with its idiosyncrasies. Way to go!
