Technology Update: Wireless Microphone Technology: Dealing with Wireless (RF) interference
The cell phone is a great example of the evolution of one of the most pervasive and reliable wireless audio devices around. BUT, even with such a refined technology, we still get the occasional interference, noise and dropped calls. Much of the interference comes from external sources that we have absolutely no control over. These external noise sources are typically other wireless users nearby, reflections or interference from physical barriers (like walls) and noise radiating from other electronic equipment.
