PART 4: Wi-Fi Emits Radio Frequencies
Wireless connections emit radio frequency signals, or radiation, just
like cell phones, cell phone towers and other wireless devices. Wi-Fi
usually transmits its signal at frequencies in the range of 2.4GHz to
5 GHz. Cordless phones often transmit in the 2.4GHz to 5 GHz range,
too, and this often causes the cordless phone to interfere with a
wireless internet connection to a nearby computer. The Wi-Fi frequency
is considerably higher than the frequencies used for cell
phones which operate in the 850 MHz to 1900 MHz range. This
higher frequency allows more data to be carried. However, as
we'll see later, it is not the frequency of the signal that
does the damage to our health. So the higher Wi-Fi frequency
isn't really the issue at all when it comes to health
considerations.
