Well, since the phases are everything that contains any direction
information, I sure hope they are not "approximately equal" for
every point somewhere in the room, otherwise you couldn't do MUSIC
or any other DOA estimator!

Thank you Marcus. If I have a point source
somewhere in the room, the channel gains (both magnitudes and
phases) from the point source to 4 antennas should be
approximately equal. Otherwise, we are not correcting actual
phase differences of two USRP B210s. Isn't it?
