> can steer the beam extraordinarily fast

The beam steering takes about 10 milliseconds. That means effectively the beam can't be steered at all during use (imagine you steer the beam to one user, send a few packets to them, then steer the beam to another user, send a few packets to them, and repeat - thats a 20 millisecond jitter the users incur - completely unacceptable).

That forces the beams to remained trained on a single user or area (covering a group of users).

You just need an array of beams (16x, etc) and do a rolling cross fade to mix the position between multiple beams.
