How does Wi Fi work?

Asked By: LilAnnie 56-60, F 11 months ago

Is it radio waves? Between wi fi and the cell phone towers, high voltage towers, GPS positioning signals beaming through the air, micro waves in the kitchen, glass optics cascading up and down the walls, the cell phone itself bombarding human bodies every second of the day, etc. Our bodies contain electral receptors and God knows what is happening to us...we are all science experiments, human guinea pigs of great interest to the future I am sure....Doomsday preppers, I'll be in the back yard digging....LOL!

Is This A Good Question? (2)

Wi-Fi, short for Wireless Fidelity, is a radio technology that lets users get high speed internet access without being tied by cord or cable to their internet connection. How? Service providers create what is called an access point by connecting specialized Wi-Fi radio equipment to a broadband modem, which in turn is linked to a high-speed internet connection such as DSL. This radio signaling equipment transmits data at very high speed using a special protocol (802.11b, for example), typically over a range of 100 to several hundred feet. This range varies depending upon the antennae used, the terrain, building construction, etc. The area covered by an access point is known in Wi-Fi jargon as a "Hot Spot". A computer (or other device such as a Pocket PC/PDA) equipped with a wireless network receiver can pick up the radio signal and enable the user to connect, wirelessly and at high speed, to the internet. Brand-name laptop computers with optional built-in wireless receivers were introduced in 2002. Wireless network cards (used in the PCMCIA slot) are widely and economically available for many of the computers without built-in wireless networking capability.

The radio waves travel by effecting the air, or sound, or light? You know what, never mind, I should look it up myself...Thank you for that nice piece of knowledge up there.

It works just like an internet connection....Just that the data packets are sent via radio waves instead of down wires.

Data packets....I'll remember that. : ) Radio waves effect the air? Or sound? Or light? Please forgive my ignorance.

Not that human beings can detect......And very minimumly and it wont effect sound or light waves at all......Though Wi-Fi can interfere with cordless phones and baby monitors.

That's what they said about those danged electricity wire they were stringing house to house. The EMF is going to kill all of us.

Yeah, I know I sound like a paranoid wearing a tin foil hat. I concede that. but you what they say..."just because you're paranoid, it doesn't mean that there isn't actually someone following you." ; )
