A shield capable of attenuating wireless signals on demand has been created using a conductive member, such as a metal mesh or perforated metal sheet, which is either coupled to ground or subjected to an electron flow. A metal enshrouded signal isolation chamber was built and a wireless router was placed inside it. With the top of the chamber open, a plurality of conductive assemblies were evaluated by placing each conductive assembly on top of the open chamber, one at a time, and measuring the resulting signal attenuation.
