Any device that sends out a Wi-Fi signal also emits terahertz waves —electromagnetic waves with a frequency somewhere between microwaves and infrared light. These high-frequency radiation waves, known as "T-rays," are also produced by almost anything that registers a temperature, including our own bodies and the inanimate objects around us.
