How very true, you have hit upon their greatest weaknesses.

Not sure what you refer to, but ultrasonic (sonar) sensors (the subject of this thread) operate in the high audio range, far far below the Radio Frequencies you mention. Use the flowchart to determine what is legal.

um ultrasonic is still sound, which is pressure waves, radio is electro-magnetic waves.. Sound waves won't ever interfere with radio waves, no matter if the "frequencies" are the same.
