Wi-Fi is a very popular network connection mechanism today. Many people prefer its use because It allows their greater mobility and dynamism while connecting.

It all started with the creation of the Internet, where several companies had a constant desire to develop a better service, and thus get the most out of this tool.

After a while, hovering around the year 2000, large companies like Nokia and 3Com decided to create the Wireless Ethernet Compatibility Alliance (WECA). Based on that, they wanted implement the use of wireless technology around the world , so that different devices had compatibility with it.



From this idea was born Wi-Fi, an enterprise started at the beginning of the XNUMXth century, which allowed teams to work together with each other through network transmission.

Wi-Fi connection overview

Its name derives from "Wireless Fidelity", the translation of which means "Wireless Fidelity", established as a telecommunications technology that makes use of its name.

In other words, allows wireless connection between different electronic equipment , which have a compatible computer configuration within their system to use the network. In this way, each device is able to connect to the Internet via a specific Wi-Fi network and, in turn, connect the computers to each other, within a single network.

Through the evolution of technology, it has been possible to adapt the equipment to use the Wi-Fi network, some of them are mobile phones, computers, televisions, music players, video game consoles, among others.

Also, this Internet connection extension is used so that every computer connected to the network is capable of exchange information data .

As for its wireless capability, it allows you to avoid using cables and other intermediaries , as each device is equipped with a receiving antenna that allows access to the platform.

How do Wi-Fi connections work?

These networks consist of a wireless adapter , which contains the connected device, and a router, which is responsible for generating the signal.

First of all, the router is connected to the Internet via a cable. This has the task of transforming the data into radio waves so that these can be transmitted through the air, within an area that varies from 5 to 150 meters in width.

On the other hand, there are the device's wireless adapter decoders, which is responsible for transforming the waves into digital data.

The information is interpreted by the computer's processor and generates the Internet connection, which it will improve depending on how close it is to the router.

It is important to note that this cycle is repeated every time the team is responsible for sending information to the internet platform, only in reverse.

Advantages and disadvantages of wireless connections

Currently the Wi-Fi network is enabled in many spaces, because it offers a greater degree of comfort and movement . This is directly related to the non dependence of cables .

Likewise, all electronic devices have high compatibility with wireless connections, regardless of the brand under which they were manufactured.


Because it travels through the airwaves, the expense for infrastructure changes is zero. This way, depending on the number of computers the router allows, more computers will be able to get the Internet connection they need.


However, a very important, and unfortunately negative, aspect is that the wireless browsing speed is slower than the wired one . The variability depends on the types of interference the signal can receive. On the other hand, it deserves security to work optimally, since any entity will be able to receive the transferred data.

In short, Wi-Fi networks have come to transform the way you connect to the internet, while also allowing all of your devices to communicate with each other.

The exchange of information is an essential aspect today, for which we thank the evolution of technology for offering us this incredible tool.
