What is Wi-Fi technology? How it works and its characteristics

In this blog, we talked about technologies such as NFC, QR codes, and Bluetooth. Today, it is time to tell a bit more about Wi-Fi technology. Keep reading because you will find out what it is, its characteristics, and how it works.

Wi-Fi technology has become something we use daily. Do you activate WiFi on your mobile device when you get home? Surely, at some time you have also asked for the Wi-Fi password in a restaurant or establishment, right?

This type of technology helps to connect devices to the internet at any time and from any place where there is a router that allows the connection. At first, connections were allowed in public places; while this technology has been evolving and becoming more and more important, routers arrived at our homes.

Having a router with a Wi-Fi connection at home made it possible to increase the use of tablets, laptops, or mobile phones, avoiding having to plug in cables to have the internet on the devices.

Just as we use Wi-Fi technology in our personal daily lives, we also do it at work. It improves mobility in the workplace. Whether they are factories, offices, warehouses, or buildings, having a wireless internet connection will be able to connect what is happening in different departments and send and share information between corporate devices.

What is WiFi?

WiFi technology is something that we cannot currently live without, or can you imagine what your day-to-day life would be like without a Wi-Fi connection? Could you do your job normally? And at home, could you watch series or movies on your devices?

These are just some of the things we can do thanks to WiFi technology, often without being aware of what this technology really is.

WiFi technology is a wireless technology that allows devices access to the internet without the need for cables. Depending on the router and the connection, it has a range of around 100 meters.

The connection is possible through infrared and radiofrequency waves. In this way, the information can be transmitted. In addition, having a WiFi technology router allows several devices to connect to the internet at the same time.

Due to the development of more and more devices and technologies, we not only have smartphones or PCs connected to the internet but also tablets or smart TVs.

How WiFi technology works

For the Wi-Fi connection to work properly, a router is necessary. This is a device connected by cables to the Internet. Through infrared and radiofrequency waves, the router is capable of sending information to the devices and for them to connect to the Internet.

For a good internet connection, the devices must be in the range of the router, and the closer to the router, the better the connectivity.

Once the router is installed, we need its identification name and the password through which we can connect the devices to the internet. For example, when you activate the Wi-Fi option on your smartphone and it is the first time you connect to that router, it will ask the name and password.

Once this action is done, the device will already be connected to the internet. Also, this step does not need to be done every time but is done the first time you connect to a particular router. Thus, the device remembers the router and its password.

Like any technology, Wi-Fi has evolved to the Wi-Fi 6 generation with more advantages and new features that will allow faster browsing.

Characteristics of Wi-Fi technology

As we have said before, to connect to a router is necessary to know the password. Some years ago, open networks and access points began to be questioned because of security vulnerabilities.

For this reason, needing passwords and creating new security protocols make Wi-Fi technology very secure. We must also bear in mind that it is a fast technology, especially the closer we are to the router.

Another advantage of this technology is the ability to have a good internet connection inside buildings.
