Wifi is a very common term these days. Most you have a Wifi connection either in your own home or in your workplace. Have you ever thought what is Wifi, and how does Wifi work? If yes, we are here to answer your questions. Wifi makes use of the radio signals to provide internet access to the connected devices as well as allowing them to transfer data even without an internet connection. It is quite interesting to know that the Wifi more than 200 times faster than an average Bluetooth technology and covers much wider distance.
So, it is essential to make use of the Wifi network connection in order to access the internet as well as to fulfill different file transfer needs. For this, understanding the Wifi technology is very important. So, we have incorporated all the details you need in this article. Without having a long description, let’s look into what Wifi is and how does it work.
Wifi is a technology utilizes radio waves to provide network connectivity to the devices. The Wifi routers will create a Wifi Hotspot, and the devices with the Wifi support can find and connect to those hotspots. Then the internet connection will start flowing from the router to the device making it possible for the person to browse the internet. The wireless router will emit radio waves between the frequencies 2.4GHz and 5GHz based on the configurations and built-in hardware which also can be chosen by the user.
There are different kinds of Wifi modems available which provide different frequencies and signal strength. Based on the coverage of the router, you will be able to receive strong signals even at a larger distance. The number of simultaneous connection also sometimes depends on the router build.
In simple words, the Wifi works by transmitting radio signals from the router which is received by a Wifi enabled device. But that’s not an apt sentence to describe the whole working of the Wifi system. So, if you need a deeper look into how Wifi works, have a look at the following paragraphs.
Wifi works by emitting radio signals of frequencies between 2.4GHz and 5GHz. Like any other radio emitting devices, it needs a receiver to receive the Wifi signals in this range and use it as a tunnel for the internet data to flow. So, our computers, smartphones or other Wifi enabled devices has this built-in function to receive Wifi signals. The reason why a basic desktop PC doesn’t support Wifi is the lack of a Wifi receiver. By installing one, you will be able to detect the Wifi from your router.
In some situations, the Microwave oven in your house (if you have one), interprets with the Wifi signals because the frequency ranges of that device and the Wifi are almost similar. Many people reported that they face problems in the Wifi connectivity while their Microwave oven is working.
There were lots of misconceptions about the Wifi signals. Someone said that it would cause headaches resulting in a lack of concentration and some others even said that it causes cancer. But, the recent reports from the trusted sources say that the Wifi signals are not causing such mental or physical illnesses. It is absolutely normal to use your Wifi whenever you need to stream hours of videos or to always stay connected on your smartphones. The reason is Wifi signals are non-ionizing radiation which can’t cause such health issues in most of the cases.
Like any other product or service, Wifi or the Wireless connections, in general, has some advantages as well as disadvantages. For your knowledge, we are going to break down the most noticeable advantages and disadvantages of the Wifi.
