Hell, even 5GHz WiFi doesn't have enough penetration for full coverage of a three-room appartment (albeit in Germany - no US style cardboard walls here). If my router wasn't dual-band I'd be screwed every time I need to take a dump
90+GHz is going to be pretty much limited to Line-of-Sight unless they have some pretty awesome tricks up their sleeves.
