What is swirl? - Definition from Whatis.com

Swirl is the term used by some people in the telecommunications industry to describe the background noise that can be present when using a digital cellular telephone phone. It's the equivalent of static on an analog cellular phone. Digital wireless phones pick up background noise just like analog phones but the background noise is different, something like the sound of air whooshing or swirling through space.
