Walker High-Def Links v. Cell Phone EMI-RFI


Has anyone experienced how well the Walker High Definition Links mitigate the effects of EMI-RFI emitted by cell phones?

I was speaking on the cell today near our system and the speakers suddenly emitted a loud pulsating/vibrating sound as I walked in and out of the room.

Just was wondering because if a cell phone can cause such a loud disturbance, what might a microwave, laundry machine, or television set be doing to distort the signal.
