How Do Wireless Networks Work?
Wireless networks work using radio waves instead of wires to transmit data between computers. That's the simple version. If you're curious to know what's going on in more detail, then it's all explained in this article.

WiFi Range: What are the Limits?
Because of the fact that the WiFi networking standard uses very
high frequency (2.4 GHz) radio signals to transmit data, its
access range is usually quite limited. How limited, of course,
depends on the type of WiFi hardware being used.

Finding What You Need
There are all sorts of different devices you can buy that will
give your computer wireless networking capabilities. If you've
taken a good look around, though, you probably have been
confused by all the different kinds of equipment being offered
-- how things that look so dissimilar do the same task? It's a
bit like buying a car in many ways, they all get you from point
A to point B ...but...
Essentially, the main difference between wireless devices is in
how they connect to your computer. There are three main
connection methods: PCI, PCMCIA and USB.
Desktops: PCI Cards
PCI stands for Peripheral Component Interconnect. It is an old
and established way of installing new equipment in a desktop
computer. If you find a wireless card that looks like a green
rectangle with something sticking out of the end, then what
you've got is a PCI card.
To install a PCI card, you need to -- horror of horrors --
actually unscrew your computer, take the cover of, and plug the
card in inside it. Scary as that might sound, it is designed to
be very easy, and once it's done your computer will have
internal wireless networking capabilities for the rest of its
life.
You should go for this option, then, if you own a desktop
computer, and you're not afraid to get your hands dirty (perhaps
literally -- I've seen years worth of dust in those things) by
installing it yourself. Or, of course, if you're willing to pay
someone to do the installation for you.
Laptops: PCMCIA Cards
PCMCIA stands for Personal Computer Memory Card International
Association. A PCMCIA slot is a small slot in your laptop that
allows you to insert these cards and so add functions to your
laptop quickly and easily. They were originally for memory
expansion, but are now more often used for networking.
Almost all laptops have PCMCIA slots. If you're not sure whether
yours does, take a look at the side of the machine -- you should
see a slot there, probably near the CD drive. Even if you do
have a slot, you need to make sure it's free, by pressing the
button to eject anything that might be in there. If it's an
Ethernet card then, well, not to worry, as you can just replace
that, but
if it's anything else then you might want to consider
using USB instead.
For 99% of laptop owners, at least, it's best to use PCMCIA --
the only reason some go with USB is because they didn't know
they had an alternative.
The Third Way: USB
Whether you're using a desktop computer or a laptop, you can use
USB (Universal Serial Bus). USB ports look like very small
slots, and could be almost anywhere on your computer -- but it
will help you to locate them if you remember that they very
rarely appear in groups of less than two. Computers have come
with these USB ports for years now, and newer computers often
come with four or even more. If you need more space, you can buy
a splitter (a USB hub) that allows you to use more devices than
you have ports for.
So where's the problem? Well, you wanted a wireless network,
right? With USB, your network won't be entirely wireless, as
there will still be a small wire between your computer and the
USB device -- it might not sound like much, but it makes USB
wireless on laptops a bit of a joke.
Another factor is that small USB devices are very easy to break
-- when I used to use USB wireless, I went through three new
receivers inside a year. This is offset, of course, by the fact
that USB wireless cards are usually the cheapest ones, and are
far simpler to install than PCI.
Essentially, if you're a laptop user without a free PCMCIA slot,
or you're a desktop user who doesn't relish the prospect of
opening up your PC, then USB is a good 'third way' for you.
If you do go the USB route, however, and you have a reasonably
new computer, you should check whether the device you're buying
supports USB2. Most newer computers have USB2 ports, and using
specially-designed USB2 devices with them can give you a
significant speed boost.
