How Do Wireless Networks Work?
Wireless networks work using radio waves instead of cables for transferring data between computers. This is the simple version. If you are curious to know what happens in detail is described in this article.
Ones and zeros.
I'm sure you know that the digital data in binary: ones and zeros. This is a kind of communication, that the translation is very good in radio waves, because the team is able übermittelttere you ª zeros as different types of arsimpel. These beeps are so fast tcappello from the public - radio waves that you can not feel, in fact they are all around you all the time. Not only on a computer with them when.
Morse code.
The operation is similar to Morse code. You probably already know that Morse code is a way in which the Scriptures so that they can be transferred at a rate könnensa radio-Punkt (short beep) and a hyphen (dash). E "was gebruikthandmatig for years and was a good way to get information from another place Aduna with the invention of the telegraph. More importantly for this example, but it is a binary system, a computer and zeros.
One could imagine a wireless network, and then, like the Morse code for the team. We define a combined radio transmitter and neucevitore and Comisiónequipo can use the points and dashes (bits, in conversation with your computerr) to transfer data from one place to another.
About frequencies.
It is doubtful, because calcolor can transmit enough bits to send and receive data at a speed that is. Indeed, there should be a limit to what can be done in half before it is just useless nonsense, right? Well, yes, but the key is that the wireless network to prevent this problem.
First, wireless transmissions at very high frequenciesSo alsgnifica more data per second can. Most wireless connections with a frequency of 2.4 gigahertz (2.4 billion cycles per second) - with a frequency similar to mobile phones and microwave. As you know, but a high frequency, this means that the wavelength is very short, and the wireless network istWarum works only in a limited area.
In addition, the Dr.ahtlose networks with a technique known as "frequency hopping" techniques. I often tientallenncias in the area, and continuously between them. This makes wireless networks more immune to interference from other radio signals that would be if only one frequency.
Access Point.
The final step is when it comes to all computers in a network gemeinsamenein access to the Internet. This is done using a device such as a WLAN access point. Zugangspunkte expensive than wireless cards for computers, radios, because zekunnen talk meto about 100 computers, and share Internet access among them. Dedicated access points are designed for large networks, but - if only a few teams eine oder as the access point, or only a wireless router.
They understand each other.
S is not good then, but as you can without completely verschiedere cable companies to work together, when everything is so complicated? Well, the answer is there are standards that all wireless devices follow. These standards aretechnical and 802.11, and sonofissato by the IEEE (Institute of Electrical and Electronics Engineers). And thanks man aderiscAnus your standard wireless networks that are so simple and easy to use.
There is no reason to worry.
If all this talk of frequencies is a bit "afraid Braun - a wireless network hardware and software for it automatically, without it. Do not think you make a mobile device, how often different, simply because het, right? Wireless networks, for all its complex mechanisms, it is much easier to use than ever expected.
