WiFi devices emit EMF (electromagnetic fields) and RF (radio frequency) radiation which is harmful to humans, pets and plants.
Wi-Fi or WiFi is a technology for wireless local area networking with devices based on the IEEE 802.11 standards.
Wi-Fi is a trademark of the Wi-Fi Alliance, which restricts the use of the term Wi-Fi Certified to products that successfully complete interoperability certification testing.
Wi-Fi is sometimes incorrectly interpreted as a shortening of Wireless Fidelity.
Wi-Fi compatible devices can connect to the Internet via a WLAN network and a wireless access point. Such an access point (or hotspot) has a range of about 20 meters (66 feet) indoors and a greater range outdoors. Hotspot coverage can be as small as a single room with walls that block radio waves, or as large as many square kilometres achieved by using multiple overlapping access points.
Wi-Fi most commonly uses the 2.4 gigahertz (12 cm) UHF and 5 gigahertz (6 cm) SHF ISM radio bands. Having no physical connections, it is more vulnerable to attack than wired connections, such as Ethernet.
Here's a partial list of devices that use Wi-Fi technology:
Cell phones and hands-free earpieces
Video game consoles
Hands-free, voice-controlled devices
Garage door openers
Keyboard and mouse
Digital audio players
Routers, adapters, extenders and repeaters
Microphones and headsets
Wireless technologies are growing and expanding at a very rapid pace which increases our exposure to EMF and RF radiation.
Comments from Dr. Magda Havas, B.Sc., Ph.D., Environmental and Resource Studies Program, Trent University.
Our exposure to radio frequency radiation (RFR) is increasing exponentially as we design more equipment that relies on higher frequencies in the electromagnetic spectrum.
Prior to World War II, this type of radiation was negligible.
Today we have radar (military, marine, aviation, and weather), we have cell phone antennas, radio and TV broadcast antennas, and a growing number of WiFi hotspots, citywide WiFi and Wi-Max antennas.
Inside buildings we have cordless phones, many of which emit microwave radiation even when they are not being used; wireless alarm systems; wireless baby monitors, wireless computers, iPads, and Smart Phones that can connect to wireless internet or WiFi.
More children are playing wireless video games than ever before and radio frequency identification devices (RFID) are placed into merchandise to provide information to the manufacturer about consumer habits.
The "smart meter" is just another source of exposure that will be placed on every home and in every apartment. Smart meters are being used to monitor use of electricity, gas and water. As part of this system, appliances are being designed to communicate directly with smart meters, all in a wireless mode, which will ultimately increase levels of radiation in the home.
