ell phones and wi-fi fit broadly in the same frequency.
But WiFi is operating much higher up the spectrum than your cellphone and more energy is being used. You would assume that WiFi modems and transmitters are safer as they are not pressed to our ear or sitting in our pockets all day. But this is wrong!
The biggest problem with WiFi is that these things throw out electromagnetic radiation 24/7, everyday, all day. And its pulsed microwave radiation just like your cell phones.
The majority of people have a cell phone but it is not always on nor near you like Wi-Fi networks everywhere. If you have a WiFi router at home, in your office, in malls, restaurants and generally any establishment; the danger is in the fact that the networks operate 7 days a week, 365 days a year constantly emitting radiation.
WiFi has a carrier signal in the 2.4 GHz range (which is nearly S HF) with some more recent devices operating in the 5-6 GHz range AND a digital pulsed signal of 10-250Hz which penetrates walls, ceilings, floors and of course humans.
WiFi radiation is usually called RF (radio frequency) radiation because it operates within the range 3kHz-300GHz. It is also called microwave radiation. Microwave radiation is a subset of RF radiation, it works in the range 300 MHz to 300 GHz.
So do yourself a favor and shield yourself, so you do not have to suffer the consequences of your constant wi-fi network!
