Cellular phone Wave

Preserva Phone opposes an identical wave (green) to the one emitted by your portable phone (red). The compensation wave in green, is shifted to a 180 degrees and cancels at the biological level the electromagnetic polluting wave emitted by the phone. The counter-wave sent by the Preserva Phone is also known as the "antidote wave".

Other applications of the same principal: The 180° out of phase wave is also used to cancel light, reduce noise, increase electromagnetic compatibility between devices, increase the antenna gain of all types of antennas, allow electromagnetic bio-compatibility of cellular phones, and more...
