Wi-Fi

By ~FedEx~

Intro

Have you ever been able to surf the net at the beach while everyone else is surfing the ocean?  Do you want to be able to check your email without using any wires whatsoever?  Do you just want wireless Internet?  Well the time has come.  This report is all about an interesting piece of technology called Wi-Fi.  You will learn about making it, working it and using it.       

Making It

What is Wi-Fi?  Wi-Fi stands for wireless fidelity.  That is a fancy way of saying that it a wireless Internet system.  This means that if you have a wireless laptop, you can access the Internet without adding any wires.       

Networks are like little Internets.  A network is what connects all of Wi-Fi.  In a network, there could be up to two hundred fifty-three clients connected to one wireless system, but it works best with twenty-five or less.  You might want to know how far and fast the networks go.  Two important factors are the power and sensitivity.  If you have more power, your Wi-Fi will go farther.  Better sensitivity allows you to access the point from farther away.   

Routers & Hotspots are things that you pretty much need to use Wi-Fi.  A router is a device that sends data across an internetwork to the destination.  In real Internet, this would probably be in a wire.  A hotspot is a place where you can use Wi-Fi best.  Some hotspots are in places like cafes, airports and hotels.  You donŐt need to be at a hotspot to use Wi-Fi, but it works best with one.  You can even use Wi-Fi at the beach!  You might have heard of an access point, but what is the difference between an access point and a router?  An access point adds wireless ability to an exiting network. But with an access point, you cannot share your Internet connection.  You need a router for that. 

You might wonder what would happen if you added an antenna to your Wi-Fi Internet. Apparently, according to Invision Power Services, all it does is it makes the range of the network larger.  

Working It

So, how does it work?!  Well, simply the computer sends and receives signals by using radio waves.  Technically, the computer sends signals, and the signals are received.  Then, they are translated, sent again and translated again.  Kind of complicated.   

How far and fast are the signals?  The newest models can go from three hundred to six hundred feet, and beyondÉ Filesaveas.com states that there are two different speeds for Wi-Fi.  The older models are 802.11b  (11 megabits per second).  The newer are 802.11g (fifty-four megabits per second.  Get it? Got it? Good!  

Bluetooth is something a lot similar to Wi-Fi.  They are both wireless Internets.  So, which is better, Wi-Fi of Bluetooth?  Well, technically, since Wi-Fi is faster and goes further than Bluetooth, it is better.  But Wi-Fi and Bluetooth arenŐt compatible.  This means that you canŐt have Wi-Fi communicate with Bluetooth, or vise versa. 

Using It

         So, why else would I want it?  If you needed to use the computer at the beach for some reason, you wouldnŐt have to use like, fifteen extension cords.  It gives the wonder and glory of the Internet without the hassle and confusion of wires.  There are also other advantages. Without any cables or wires, you can walk all over the place with your computer.  If you are at lunch or in a meeting, you can use your computer without messing with any wires or extensions that people can step on.  Therefore, you can save time by checking your Email at lunch ectÉ  You can also share files and such much easier.   

Are there any other products that use it?  And who uses Wi-Fi most? According to Filesaveas.com, Wi-Fi can be used with webcams, radios, the Nabaxtag Wi-Fi bunny, T.V and, of course, computers.  That is a lot of wireless. Everyone can use it, but some people that use it a lot are business travelers, college students and even just regular people at home that use it just to be efficient.      

So when is the best time to use it?   And how do you use it?  To start, all you really need is a mobile PC and a wireless PC card.  You can also use a wireless keyboard and a wireless mouse.  You also might want to know were all the hotspots near you are. Once you have that, then you can simply use Wi-Fi like regular Internet, except without the wires.  Therefore, if you are somewhere with no wires, like the beach, you can still use your Internet.

Conclusion

Now you know what Wi-Fi can do.  You know more about making, working, and using it than you ever thought you would know.  Using it on a beach might sound cool, but there are so many more things that you can do with it.  And now you know some of them.
