Many moons ago I started hearing all this talk about WiFi and how wonderful it was, and when I asked someone "What is Wifi?" I was given a complicated explanation that left me with more questions than I started with. I mean, what the heck is "IEEE 802.11" anyway?!

So I did some more research and over time I gained a decent understanding of what WiFi was, all the time making sure I looked for the easiest definitions to digest so that if anyone ever asked me, I'd be able to give them a clear explanation rather than rambling away in techno-jargon, only to see their eyes glaze over as they lost comprehension.

Eventually I decided to put the knowledge I'd found together into a blog. You can check it out So the topics below are summaries of what I have discussed on my blog. I'll add a new summary for each blog post I make, but if the summary doesn't do it for you be sure to head to the original blog post in it's entirety via the links in the "Want More Info About WiFi?" section below.

One day in the not-too-distant future we'll be wondering how we ever suffered with cords and cables lying about the place for so long. You'll wonder why it took you so long to get on board. This is freedom for the 21st century, pure and simple.








How Does WiFi Work?Just How Can I Surf The Net Without A Phone Cable?I know it might sound nuts - how can all this information that I'm currently uploading and downloading from my computer through a phone cable be transmitted "through the air?!" Well I'm glad you asked.WiFi works, in essence, exactly the same way a Television or Cell Phone works. They don't have cables attached to them for transmitting information and neither will your computer once you start using WiFi.Basically, WiFi uses radio waves to transmit the information to and from the internet or your computer network. When a website wants to communicate with your computer it sends the information to your modem as it does now on your wired connection, then the information is passed on to a
