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.
