With the licensing environment that exists today the answer is a definite "uhhhh maybe?!"

If you wanted to do it with LTE gear no since it's fixed to non-public spectrum.

If you did some serious wifi hacking to use the same concepts you might be able to. But with the area that wifi covers and the generally terrible power efficiency of the amplifiers I'm not entirely sure you'd want to. I don't think you'd be able to call it pCell but you could probably use the DIDO ideas and make it happen if sufficiently motivated.

I don't see any legal reason why you couldn't do something like this today. There are already WiFI routers that do beamforming and this just seems like an application of beam forming where your antennas are much further apart.
