What they have demoed and are building out now is a pretty incredible advance in modern radio systems. So there is healthy room for skepticism.

It seems like there would be some major engineering challenges ahead, with predicting localization and movement of each receiver to adjust the location of the 'cell', and dealing with multipath. So this might explain why they are going slowly with building it out.

But I think that it is not snake oil, just a disruptive innovation that is slowly trying to get a foothold after coming out of relative secrecy in development for years. If they get it right, though, then it will absolutely reinvent the cellular industry.
