How does Wi-fi technology work? Radio waves are the real deals through which Wi-fi works. Read more about this intriguing technology!
Internet users have become so attached to hotspots and the inexhaustible source of information that few stop to think about how Wi-fi technology actually works.
During the old times, it was really difficult to pass information from one place to the other. You would need to pass information about anything through a man visiting and going in person to deliver the message. The whole thing required time, and it was very hard to deliver your message to loved ones.
Internet Has Made Things Easier
However, that era has ended. Passing information to someone has become a lot easier these days. Thanks to internet technology and mobile phone network operators. They have made things pretty much easier for everyone. You call someone; your message goes through within seconds. All you need is an internet connection, and you are good to go.
This is an era of the Internet where people spend a lot of their time using their mobile phones and computers. Smartphone technology has changed the world quickly. Now, you see, everyone has a smartphone these days. There are so many users having internet connections and access to their social media networks. In such a scenario, businesses have also shifted online to have the maximum reach.
Wi-Fi Technology and How it Works
Having such advanced technology made life easier for so many people. However, no one of us tries to ponder how things work on the Internet, how this information passes from one device to the other having no wired connection. How does Wi-fi work, and how do we connect our devices to the modem? Let’s check out this guide to see what we need to know about Wi-fi.
Basic Idea about Wi-Fi Technology
Wireless internet is still a form of sorcery for people lacking some basic knowledge regarding modern technologies. We are too obsessed and busy using wireless internet that we don’t even bother to have extra knowledge regarding Wi-fi.
Wi-fi is an acronym chosen to describe IEEE 802.11 technologies. Wi-fi networks make use of radio waves to transmit information between devices capable of emitting and reading such signals.
The computer, smartphone, or any other device used for accessing the Internet should include a wireless adapter that will translate data sent into a radio signal. These signals are just like the signals used for walkie-talkies in old times. These signals work both ways.
Your device receives signals and sends them back to the adapter, from where the information goes through.
Role of Radio Frequencies
Now, the signal has a specific frequency at which they move from our device. This frequency is a little higher than we observe for walkie-talkies and TV remotes. Usually, Wi-fi operates at 5GHz or sometimes 2.4GHz. 5 GHz has more range for the signals to spread around the surrounding.
It can cover almost 80 meters area from the router. If you are using Wi-fi in your school or college, the frequency will be higher to cover the whole area. The same goes for airports and supermarkets.
Antenna and Decoder Roles
The next step requires the same signal to be broadcast via an antenna to a decoder known as the router. Once decoded, the data will be sent to the Internet through a wired Ethernet connection.
The process goes in both ways, allowing for information to come and leave from the end user.
External Linking Through Wi-Fi
Wireless technology can be used for linking external devices like printers, and keyboards, bringing the same advantages of space economy and functionality. This technology enables us to connect different computers together and use information from one device to the other. Wi-fi connects all the computers to a signal computer which allows you to see information passed.
Availability Of Wi-Fi
The term hotspot defines a source of Wi-fi Internet, which could be open or password protected. Wireless hotspots are becoming a feature of almost any home, public place, or private space. It is very common for restaurants and hotels to allow wireless Internet connections to their users and for Wi-fi to be available on school campuses. The area covered by a hotspot depends on how powerful the emitted signal is and how many solid obstacles are present between the end user and the router.
Wi-fi coverage, especially in metropolitan areas, is in continuous growth, and there are some cities around the world that have implemented full wireless network coverage.
Wi-Fi technology simplifies the life of the average Internet user in a powerful way. There is no need for cables, and mobility is thus encouraged. Wi-fi technology enables the existence of on-the-go offices, and employees can work remotely from almost any corner of the world.
Are these Signals Hazardous to Us?
Certainly not. However, if the frequencies keep extending, it could be a little concerning, however, if you have a Wi-fi connection at your home. It should be fine to use it as it has almost zero threats. It just depends on the signal strength and frequencies we operate on.
You are witnessing new tech day after the other without knowing the basic information. There is a need for public awareness of any technology available, like Wi-fi. We use it, but we don’t know how it functions. Hope this guide has helped you understand a little more than you knew earlier about Wi-fi.
Wi-fi technology is certainly shaping the world and bringing everything and everyone closer together.
