Wi-Fi Networking - What to Look For: Range, Speed and Standards
Not sure what you're doing in your wireless card shopping? Want
to make sure you're buying the right thing but just have no idea
what it is you're looking for? Well, you've come to the right
place. When you're looking to buy a wireless network card, I can
tell you right now that you're looking at three key issues:
range, speed, and standards.
A Typical Specification
This is a specification for a Linksys wireless PCMCIA laptop
card I just bought:
11 Mbps high-speed transfer rate; interoperable with IEEE
802.11b (DSSS) 2.4Ghz-compliant equipment; plug-and-play
operation provides easy set up; long operating range (up to 120m
indoor); advanced power management features conserve valuable
notebook PC battery life; rugged metal design with integrated
antenna; compatible with virtually all major operating systems;
works with all standard Internet applications; automatic load
balancing and scale back; model no. WPC11. (source: amazon.com).
Now, some of those things can be pretty much ignored. Really,
'virtually all major operating systems'? That means nothing. The
reason I've put it here, though, is so you can see which things
are important to keep an eye out for.
Range
See where it says 'up to 120m indoor'? This tells you that the
maximum range of the wireless card you're looking at is 120
metres -- that's what it would be if everything was perfect. In
practice, thick walls and interference can reduce this number by
as much as 90%.
Without enough range, your wireless network is going to be
pretty useless. It's not much fun having no wires when you have
to keep all the computers in the same room to get them to
connect to each other.
As a rule of thumb, unless your walls are made of drywall or
wood, it's best to buy about four times the strength you'd think
you'd need. Even in perfect conditions, get twice as much, to be
safe. If you need to convert from metric to imperial units,
remember that there are 30 centimetres (0.3 metres) in a foot
and about 2.5 centimetres in an inch -- you shouldn't have too
much trouble.
Speed
Do you see where it says 'Mbps' in that description? That
number
is the speed of the wireless connection. 11 Mbps is about one
and a half megabytes per second -- to convert megabits (Mb) to
megabytes (MB), just divide by eight. 802.11b wireless cards all
have a speed of 11Mbps, while 802.11g ones run at 54Mbps -- the
next generation will be even faster.
Speed is important to your wireless network because it's going
to directly influence how long you have to wait for things like
files to transfer from one computer on the network to the other.
It is less important for Internet use, however, because there
are currently very few Internet connections running at speeds
over 11Mbps -- it's really as much as you need, at least for now.
Standards
Somewhere in the specification of what you're looking at, you
should see the number '802.11', followed by a letter 'a', 'b' or
'g'. This is the standard that the wireless device conforms to,
and tells you whether you will be able to use it with your other
wireless devices.
Basically, 802.11b and 802.11g are compatible with each other.
802.11a is not compatible with either and is quite a bad
standard all round, so you shouldn't buy 802.11a. Out of b and
g, b is cheaper but slower, while g is more expensive but
faster. It's worth considering that adding a b-speed device to a
network that has g-speed devices will often slow the whole
network down to b-speed, making the g-devices pointless.
If your wireless device doesn't conform to the right standards,
it's not going to be much good to you. I often see naive people
bidding for used wireless equipment on eBay, not realising that
it's going to be terribly slow and not work with any other
equipment they might have. Always make sure that you check what
standard the wireless equipment is -- if you don't know the
802.11 letter, don't buy it!
