Wouldn't a "repeater" only work as a reflective surface such as a mirror? You would have to have perfectly angled mirrors placed around corners and stairways.
It would need two antennae. One aimed at the point of origin (e.g. router) and one aimed at the direction of rebroadcast (e.g. a room). I don't see this technology taking off anywhere soon; even in an open office space one would need to get rid of obstacles like cubicle walls etc. I wonder how they're proposing to tackle this.
