How does wireless internet run?

How does wireless internet run? There is hardly any person in the present time who has not used the Wireless Internet or wireless Internet. In the present technology age, where so many ways to use the Internet are needed, wireless internet is something different.Many of us may know about it, but do you know how this wireless internet works? A wireless network or Wireless Local Area Network (WLAN)Both do the same thing as a wired connection — which is used to link a group of computers.

Wireless as the name suggests, it does not use a wire. So install, operate, is very fast and easy to install this system. So Internet Connection are the most demand of wireless internet.But do you know how this wireless internet runs? If not, you must read this on top of today's article Wireless Network. So let's start without delay and know how this wireless network works.

Wireless

Wireless is the convectomy of two words Wire + Less. It is also known as wireless in Hindi, which means that wires are not used. This is a way in which signals is transport, as in a Wired connection, without any wires or optic fibers.They propagate in Signals free space. Often we wireless, refer wireless communication. A way in which information is exchanged between two devices that has not been connect from any wires.

Wireless networks operate occurs Radio frequency (RF) using technology. It is a frequency within electromagnetic spectrum that is associated radio wave propagation.When an RF current is supplied to an antenna, then an electromagnetic field is created and it is able to propagate through space.

The cornerstone of a wireless network is a device called an access point (AP). The primary job of an Access Point is to broadcast a wireless signal that computers or other devices can detect and also "tune" into.Since wireless networks are usually connected to wired devices, an access point serves as a link to other resources found in a wired network, such as an Internet connection.

To connect to an access point and to join a wireless network, computers have to be equipped with wireless network adapters.They are often built into the computer, but if this is not the case, then any computer or notebook can also be made wireless-capable or compatible using an add-on adapter that is plugged into a computer. In the case of empty expansion slot, USB port, or notebooks in a PC Card slot.

Where is wireless used?

Before knowing how wireless communication works, we should understand which are the areas where these wireless technology is applied. In most cases, we use wireless communication to transmit data.It is either one direction, such as in radio or TV broadcasting. Or in two-way data transfer where one entity acts as a transmitter while the other acts as a receiver.

In this second scenario we can use satellites, Wi-Fi access points or mobile networks like 3G, 4G or upcoming 5G as an intermediate point which helps us in this type of communication between transmitter and receiver. .

How does wireless communication happen?

In wireless communication, we have to transport data without wires or wires. Signals (electromagnetic waves) are used to transport this data.

Now the question arises that how can we create signals and send them to wireless?

The answer is, everything starts with a transmitter, where an oscillator generates a periodic wave. These signals then propagate through the device's internal wires to the antenna.Since the antenna is a conductor, the electric current is then carried forward to the end of the antenna. This antenna then radiates alternating current through an electromagnetic wave. This is the start of the process of Wirelss i.e. The antenna converts electric current into waves.

What is the frequency of the signal?

Often people ask us this question, what is the frequency of these signals and who assigns them. The answer is how fast these signals change. After being generated from the Oscillator, it decides how many different frequencies the output waves have. These frequencies are used for different tasks.We call the range of these different frequencies a spectrum. This spectrum is divided into different areas according to their usage. If we take example of usage then : radio-navigation, radio-location, broadcasting, mobile communication, ISM band, satellite, space research and many more.It is the government authorities such as TRAI that decide which frequency ranges to use for which purpose.

How do Signals travel?

These signals usually do not travel in a straight path till the receiver when they are transmitted. The antenna in the transmitter radiates the signal in all directions.These waves have to be reflected by hitting the buildings, along with they have to diffract in sharp edges or have to be scattered in small objects. But still all of them reach the receiver in the end.On their way, the waves have to deal with different attenuation and delay. The receiver captures all the signals as a combined signal. When there is more than one route between transmitter and receiver, then we call that channel a multipath channel.

What happens inside the transmitter?

We know that the receiver has to struggle to decode the data from the distorted and mixed signal. This is not a trivial task as the captured signal contains a huge amount of unwanted components. To make this task easier, we have some additional steps in the transmitter.The transmitter performs the encoding process before sending the data. With this operation additional bits are added to the message, which makes it easy to do data recovery in the receiver. After encoding the bits are mapped into symbols, modulated and then passed to the antenna.

What are the Benefits of Wi-Fi Wireless Network or Advantages of Wireless Network?

There are many advantages of Wireless Internet Network or Wireless Internet, about which we all must know. So let's know more about these advantages:

Provides Convenience

You can access Wifi Wireless Internet from anywhere. Just your device should be within the coverage area of ​​that wireless network.

is mobile

With these features, you can take it anywhere. Like broadband, you do not have to be fixed or tied to a desk or table. You can take it to any corner of your house or building.

Provides Productivity

There is more ease in using it, due to which it helps you to become more productive. With this, the resources of a company can also be used correctly, which helps in the growth of the company.

Easy setup

In this, like other internet networks, you do not need string cables, so installing it is very quick and cost effective.

is expandable

You can easily expand wireless networks whenever you want with the help of your existing equipment, whereas in a wired network you may need additional wiring which is a waste of both time and resources.

Provides Security

The world has made a lot of advance in wireless internet service, due to which these wireless networks provide very robust security protections.

Cost is also minimal

Since the wiring expense required for installation and operation of wireless networks is very low, the overall cost is very minimal.

Conclusion

I hope that I have given you complete information about how wireless internet works and I hope you people have understood about what is wireless internet and how it works.If you have any doubts about this article or you want that there should be some improvement in it, then you can write low comments for this. From these thoughts of yours, we will get a chance to learn something and improve something.
