This looks like it'd work for fixed broadband installations (say, for people in rural Montana or Ontario), but I'm less convinced it'd work well for cell phones because the tower would need to predict your movements in advance of you actually moving there in order for it to know where to build the constructive interference.
The receiver can determine the "Direction Of Arrival" of a received signal which it uses for beam forming (this is how it typically done, don't know anything about pCell).

Perlman demonstrates [0] some sort of 'adaptive algorithm' that pCell uses to track real-time a UE's position.

I'm surprised at how rough the audience was for the presentation. I wonder where those emotions came from.
