Wireless Networking Cards buying guide

Ok, so you read all the cool stuff and heard all the great things about going wireless, then just hit you. But it seems that you do not know or care, but it struck you. That's what the little voice in your head saying do it and that was all. Unfortunately, it was some time ago and since that moment you have done your part. You have some research on what was necessary to upgrade your computer, but it's just so damn confusing. You keep thinking, why can not someone just give me some basics, so I feel more comfortable with all this upgrade process.

If the above paragraph describes you, and if you are the typical computer user no doubt, it is time to breathe, calm nerves, take a coffee and settle down, because I hope this article may provide some understanding of at least one aspect of going wireless - network adapter.
Like most typical computer users who do you love your computer and you good enough to surf the web, use email and you probably even have enough skilled with your word processor favorite, but when it comes to some of the more technical aspects of your computer or computers in general, you're probably as close to a "deer in the headlights, as you can get.

Hey, no problem, as they have stumbled across a source that we hope will shed some light on this wireless network card abyss. See, these skills are useful for.

Let me start by saying that when it comes to choosing a wireless network card, you can almost overlook all those things, except for three factors: range, speed and standards. Ok, let's do it and take a look at some details.

Below is a typical specification for wireless network card. This happens to be a PCMCIA card Linksys wireless phones. Frankly, I can not tell you if this card rocks or it sucks, I just use it as an example. And with that, we will take a closer look.

Take a look at where it says up to 120m indoors. This means that the maximum range of the wireless card is 120 meters - that if everything was perfect. And by the way, a meter is equivalent to about 39 inches or 3 feet. Could be in the real world where nothing is ever perfect interference caused by thick walls and other energy sources, and the list continues to reduce this figure by nearly 90% - so just be aware of that.

And without proper range, your wireless network is not wireless and is therefore - no value. There is no need to go wireless if you need to keep your computer next to the wireless port to enable it to work, or if you have multiple computers to keep them all in the same room to get them connected together to create other.

Generally, unless your walls are plaster or wood, it is best to buy about four times the force you think you need. Even in perfect conditions, you get twice as much as you think you need - just to be safe.

Another look at the description and find where it says Mbps. Mbps is the speed of the wireless connection - 11 Mbps is about half past one megabyte per second. All cards have a speed of 802.11b 11 Mbps, while 802.11g cards operate at 54 Mbps, almost five times faster. And of course the next generation will be even faster.

It 'clear that speed is important for the wireless network, because it will directly affect how long you should wait for a connection, the speed of loading pages, file transfer speeds, and your overall experience of the computer is always better when the things load faster. Do not know about you, but if something requires more than a few seconds to download, I started to get impatient.

However, since there are at present very few Internet connections operating at speeds above 11 Mbps - is really all you need, at least for now.

You probably noticed in the specifications above, the number 802.11, followed by a letter b. The b is the standard that the wireless device is also compliant. Currently, there are three standards - a, b and g.

In short, 802.11b and 802.11g are compatible, while 802.11a is not compatible with either. Due to incompatibility issues with the other two standards, and because it is an old standard less robust than it should stay away from the cards to use.

Between b and g, b are cheaper, but more slowly, while g is more expensive but faster. It is also interesting to consider the addition of a state device B to a network that ag-speed devices often will slow the entire network down to b-flow, which makes sense g-unit . Basically, the network will operate at the speed of its weakest link.

If the wireless device does not respond to standard right, will not be very good to you. I often see people ignorant of offers on eBay to use wireless devices, without realizing that it will be painfully slow, and not necessarily with other devices, they could have. Always check that the standard for wireless devices to use and do not know if the letter of 802.11, do not buy it!
