What is it, what is it for and how does WiFi work? - Advantages and disadvantages

Wi-Fi is a very popular network connection mechanism today. Many people prefer its use because it helps them allows a greater mobility and un greater dynamism when logging in.

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

After a while, hovering around the year 2000, big companies like Nokia and 3Com decided to create the Wireless Ethernet Compatibility Alliance (WECA). On this basis, they wanted put en implement the use of wireless technology around the world , so that different devices are compatible with it.

Wi-Fi was born from this idea, a business started in the early XNUMXth century, which allowed teams to work together through network transmission.

Overview of the Wi-Fi connection

Its name comes from "Wireless Fidelity", which translation means "Wireless Fidelity", which is established as a telecommunications technology that uses its name.

In other words, it allows wireless connection between different electronic equipment , who have a compatible computer configuration within their system to use the network. In this way, each device manages to connect to the Internet through a specific Wi-Fi network, and in turn, they link the computers together, within a single network.

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

Likewise, this Internet connection extension is used so that every computer connected to the network is able to exchange information data .

Regarding its wireless capability, it allows avoid the use of cables and other intermediaries , since each device has a receiving antenna that provides access to the platform.

How do Wi-Fi connections work?

These networks are made up 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 is responsible for transforming the data into radio waves so that they can be transmitted in the air, in an area whose amplitude varies from 5 to 150 meters.

On the other hand, there are the decoders of the device's wireless adapter, 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 will improve depending on its proximity with the router.

It is important to note that this cycle repeats each 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 activated in many spaces, as it offers a greater degree of comfort and movement . This is directly related to the cable non-dependence .

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

Because it travels by radio waves, the expense for infrastructure modifications is zero. In this way, depending on the number of computers allowed by the router, several computers will be able to receive the Internet connection they need.

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

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

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