Ok, so you read all the cool stuff and heard all the great things of going wireless and then it only took you. However, works that do not know or care about, but you did. That was, "said the little voice in your head," do "and that was it. Unfortunately, this is a bit 'ago, and since this time" "you made your contribution. You have some research into what is necessary to upgrade your computer, but everything is just so damn confusing. You always thought, why not give only to someoneme some points of principle, so at ease with all this "upgrade" of the process.

If the section above and if you are the typical computer user is likely, then it's time to breathe, calm nerves, grab a latte and in this article, as it hopes will be a little understanding ', at least on one aspect of scale wireless system – the network card.

Like most "typical" users 'computers', love your computer and you have good enough for surfing the web, withE-mail and you will probably have even set up quite well your favorite word processing, but when it comes to some of the more technical aspects of computers or computers in general, is probably as close as possible "Reh in the headlights "as you can get.

Hey, no problem, because we have stumbled on a source that will hopefully be a little light on the wireless network card may need to launch the abyss. See, these skills useful for research.

Let me startsay that if they ignore the choice of a wireless network adapter, you can almost all the Hoopla with the exception of the following three factors: range, speed of source and standards. Ok, let's do it, and take a look at some special functions.

Here is a typical specification for the wireless adapter. That only happens to be one of a PCMCIA card Linksys wireless laptop. Frankly, I can not tell if this card rocks or stinks, I am just one example. Andwith which we look more closely.

Here's the description from Amazon: 11 Mbps high speed transfer, interoperability with IEEE 802.11b (DSSS) 2.4GHz non-compliant equipment is plug and play allows easy configuration, long range (up to 120m indoor), Advanced power management functions to receive the useful life of batteries for notebooks, rugged metal design with integrated antenna, compatible with virtually all major operating systems, works with all popular Internet applications;automatic load balancing and scale back, model no. WPC11

As I said earlier, most data are ignored. To begin with, compatible with virtually all operating systems. "This does not mean anything. It 'easy to add fluff to the description to make the paper better.

Range

See where it says "up to 120m at home." This means that the maximum capacity of the WLAN card 120 meters – that everything was perfect. And, incidentally, is a meteran amount of about 39 cm or 3 feet. However, in the real world, where nothing is ever perfect disturbance caused by thick walls, going to other energy sources, and that number could be reduced by up to 90% – so just be aware of this.

And without enough range wireless network is not wireless, and then – without value. There is no point to go wireless if you use the computer next to the wireless connection, so you have a job or maintainIf you have multiple computers to keep them all in the same room for them to connect to each other.

The rule of thumb, unless the walls are drywall or wood, is better than about four times the amount you think you have to buy. Also received in perfect condition, twice as much as you think you have to – just to be safe.

Speed

Check out the description and see where it says Mbps Mbps is the speed of wireless connection – 11 Mbps is about a year andhalf a megabyte per second. All the 802.11b wireless cards have a speed of 11 Mbps, while 802.11g 54 Mbit / s to perform, or nearly 5 times faster. And of course, the next generation will be even faster.

Obviously, speed is important for the wireless network, because it goes directly to affect how long you expect to get in touch as soon as loading pages and file transfer speeds, and your entire PC experience is always better when things are faster to download. I do not know howBut if something requires more than a few seconds to download, I start to become impatient.

However, Internet connections, because so far there are very few, with a speed of 11 Mbit / s – is really what is necessary, at least for now.

Standard

You probably noticed in the above figures, the number 802.11, followed by a letter b. B is the equivalent standard for the mobile device. Currently there are 3 standard – a, b and g.

At this point, 802.11b, and802.11g with each other, while 802.11a is not compatible with the two compatible. Because of the problems of incompatibility with the other two standards, and why you are using an old standard, less robust I would stay away from cards.

Between b, g, b is cheaper, but slower, while g is more expensive but faster. You should also consider that the addition of a B-device speed network, the g-speed devices are often slow the entire network up to b-speed so that the g-unit is meaningless.Basically, the network will operate at a speed of its weakest link.

If your mobile device does not match the rules of law, is not going to do very well. I often see people misinformed offered to use wireless equipment on eBay, not knowing that it will be terribly slow and not with other devices that work. Always check that the devices used in wireless standards and you do not know, do not buy the letter 802.11,it!
