There are two common frequency bands that all cell phone carriers use. The Cellular band commonly referred to as 1900 uses the frequencies 1850-1990. The other band is PCS which is the 800 MHz band uses frequencies in the 824-894 range. Most of our cellular phone signal products work on one or the other. Mistake: Sleeping with your cell phone
Some people are so attached to their cell phones that they sleep with them on their nightstand or even under their pillow. Bad idea. Cell phones pump out electromagnetic radiation whenever they're on - which means sleeping with one nearby boosts your exposure all night long. What to do? Put the phone on "airplane mode" (which shuts down the transceiver) or turn it off. If you need to be available for calls, place the phone several feet away from your bed.
