How Does Wi-Fi Technology Work: A Guide By Network Experts

Introduction

Once the world got the taste of the internet, there was no slowing down. More and more people came on board with the internet. This created a demand for easier internet access.


According to a study made by Pew Research Center, people today spend more time on the internet than watching television. This also includes online streaming on torrent websites like ipiratebay.org.


Although people use wifi without a second thought, nobody knows how it works. That being said, we have come with this article to discuss what wifi is and how it works.

What Is Wi-Fi?

Wifi is a networking technology that allows different devices to connect with the internet. There are several mutually compatible versions of wifi. They are all based on IEEE 802.11.


So, what is this IEEE 802.11?


It is the bare minimum standard that specifies the protocols for implementing wireless local area network communication in different frequencies.


The first version of wifi was released in the market in 1997. It got its first update in 1999. The updated version is now referred to as WiFi 1 or 802.11b. This wifi version gave the users a speed of 11 Mbits per second.


In comparison, the latest version of WiFi, WiFi 6 or 802.11ax, can allow users to transfer data at an astonishing speed of 11GBits per second. You Can read laptop can't detect wifi

How Does Wi-Fi Work?

Most computer users know little about how wifi networks work. But even a little bit of background knowledge can go a long way towards making your internet connection zip along.


As we already know, wifi uses radio waves to transmit data from one device to another. For wifi to work, you need a modem connected to a wireless router. Once the setup is complete, these points will be considered wireless access points.


The wireless access point will now act like a hub that generates wireless signals and allows wireless devices to connect to the internet.


If we divide the working of wifi technology, it can be divided into three following steps.


  • Step 1: The Modem needs to have a cabled connection to access the internet.


  • Step 2: The router is then connected to the modem. The router used the cable connection and sent them out into the atmosphere in the form of radio waves.


  • Step 3: The devices with the wifi receiver card will be able to connect to these radio waves, which will ultimately connect you with the internet.


To experience the best quality wifi, you need to be as close as possible to the access point. If you are too far or have too many objects between the connections, you can experience a slow internet connection.

Advantages Of Wi-Fi

Today, most computers and cellphones sold in the market are equipped with wireless technology, including WiFi.


The benefits of using WiFi over a wired connection includes:


  • Productivity: With the right use of wifi, it can increase the productivity of any business. Wifi keeps the employees in contact all the time, which enhances communication. With effective communication, team members can give their 100%.


  • Convenience: Wifi gives you convenience. Your devices don’t need wired infrastructure to access the internet. It simply needs to locate a WiFi signal.


  • Expandability: Expandability with WiFi is super smooth. Bought a new tablet, no problem. You just need to increase the number of authorized devices, and you are good to go.

  • Mobility: Users aren’t tied down to the cable wires to use the internet. With the wifi signal, you can access the internet from anywhere (as long as you are close to the access point).

Disadvantages Of Wi-Fi?

Although the advantages of WiFi outweigh its disadvantages, it's important to know what disadvantages make wifi offer.


  • Range: WiFi has a limited range. That means a single access point might not cover the whole floor.


  • Security: Because the wifi signals travel through the air, they can easily be intercepted. This is the reason why people are asked to encrypt their wifi signals.


  • Disruption: WiFi signals transmit data in radio waves. That means, if an object is caught between the connection, the connection suffers a disruption.

Wi-Fi might Be Fast, But Not Always Strong!

Although Wi-Fi is fast, have you ever wondered why connecting to the nearby Wi-Fi can be troubling? The answer is that they are radio signals and radio signals become weaker with distance.


In addition, barriers like thick walls, metal shelves, and other objects can obstruct radio waves. In fact, if there are too many wifi networks, they might interfere with your link.
