The MRET Cell Guard utilizes patented Noise Field Technology. This technology does not block or shield radiation from wireless communication devices (like cell phones, cordless phones, wi-fi routers, televisions, or Bluetooth) as that would inhibit device signals and cause reception issues. Instead, it functions physiologically by interfering with the body's perception of the information-carrying radio waves (ICRW), thereby changing how the body is affected by electromagnetic radiation (EMR). This is compared to how sunscreen alters the body's response to the sun, or noise-cancelling headsets protect hearing from loud noises, where the damaging waveforms are still present but the body is protected.
