Today's world is incomplete without the Internet, and Wi-Fi has a huge contribution in making the Internet facility easy and convenient. Earlier, when the Internet had to be used, the computer or laptop had to be connected directly through a wire. But today, Wi-Fi has ended this hassle. Now the question is how the Internet reaches your mobile, laptop, or smart TV without a wire.
The full name of Wi-Fi is Wireless Fidelity. This technology uses radio waves to send and capture data in the air. Just as the waves emitted from the radio station reach your radio and turn into sound, similarly the waves emitted from the Wi-Fi router reach your mobile or computer and turn into internet signals there. This process is so fast that we do not feel any kind of delay.
When you use Wi-Fi, first the internet reaches the router from the broadband connection or mobile network in your home or office. The router converts that internet signal from digital data into radio waves. These waves spread in the air and the Wi-Fi receiver of your device catches them. After this, the receiver converts these radio waves back into digital data and this is how your phone or laptop connects to the internet.
Wi-Fi mainly uses two types of waves. The first is the 2.4 GHz band, the specialty of which is that its range is more but the speed is a little less. The second is the 5 GHz band, which gives faster speed but its range is a little limited.
This is the reason that if you move away from the router or there are walls in between, the Wi-Fi signal can become weak. Nowadays new technologies like Wi-Fi 6 and Wi-Fi 7 provide even faster and reliable connectivity.
If there was no Wi-Fi, every device would have to be connected to the Internet through a wire, which would not only lead to a web of wires everywhere but would also make it difficult to use portable devices like mobile and laptop. Wi-Fi has truly made the Internet mobile and easy. Now you can surf the net, make video calls, join online classes or enjoy entertainment from anywhere.
Wi-Fi not only makes our lives smarter but also keeps us completely connected. This technology gives us a wireless Internet experience by transmitting data from one device to another with the help of radio waves spread in the air. This is the reason why Wi-Fi has become one of the most important technologies in today's digital world and in the coming times, we will see even faster and safer versions of it.
