Wi-Fi Technology

          At the present time, everyone is able to use the Internet. The most credit for this goes to wifi technology. Even if we want to use the internet on mobile, computer, laptop, we now use wifi for that.

          Welcome friends, in my Digital Tech Akshay blog, where you get digital technology, computer things, internet things, and social media-related information. So let's start today's wifi article.



    What Is Wireless Fidelity (Wi-fi)?

              The full name of wi-fi is Wireless fidelity. Today wifi is a very popular wireless networking technology which uses radio signals to provide high-speed internet and networking connection. wifi was invented by John Os Sullivan and John Dean in 1919.

              Actually, it is a wireless networking facility. Also known as VLAN, Virtual Local Area Network. This is a technology through which we are using the internet and network connection today. With its help, you can easily connect devices like mobiles, laptops, computers, and printers to the internet and network.

              This technology comes within the local area network. This means that its range is limited to a low area. Through this, we can connect to the Internet up to limited space. Not only the internet but nowadays people also transfer wirelessly through it. Such as Share-It and Xender apps.

              The wifi aliens company manufactures wifi devices and Wifi direct. Its name is derived from hifi ie High Fidelity. wifi is a standard that allows the computer to be connected to a wireless network.

              All the smartphones, laptops, computers in the present time have a wifi chip through which we and you connect to the wifi router and use the internet.

              Through the wireless router, you can access the internet by connecting the device with wifi. But the router also has to use DSL and cable modem to stay connected to the internet. Which is different from ISPC or else internet access is not available.

              Today many types of hot-spot devices also come. In wifi devices which multiple smartphones & devices are connected to wifi internet simultaneously through a wireless signal.


    How Does Wireless Fidelity (Wi-fi) Work?: -

              Wi-Fi technology includes such a device that transmits the wireless signal. Which is a wi-fi router or hot-spot in the air. In this, the wireless router connects to the Internet and converts the information into radio waves. 

              And the wifi device creates an area of a small wireless signal around itself by connecting to the existing wifi signals in the environment. 

              This small area takes the form of a wireless local area network, ie WLAN. All the devices in this small area like smartphones, laptops, and printers, these devices have an inbuilt wireless adapter. 

              With the help of which these devices can receive the wifi signal easily. But desktop computers do not have an inbuilt wifi adapter. That is why we can use wifi by putting an adapter through the USB port from it. 

              If you ever go to the airport, railway station, coffee shop, then you are definitely in the wifi zone at that time. There are many such cities also where the government has set up a wifi area. Where people can go and use it for the internet freely.

              However, a wireless router is enough for a house. Keep in mind that the speed of the wifi network gets higher with the router and decreases with increasing distance. 

              Today's smartphone also offers a hot-spot option with wifi service. That is, you can not only use the wifi network but can provide an internet connection to many other devices from your phone's hot-spot devices.

              Suddenly, if the internet data gets exhausted from your mobile, then you can take an internet connection on your friend's hot-spot by turning on your friend's wifi.

              Friends, let's know what a Mobile hotspot is?

              It is an ad hoc network and enables devices to connect to each other without a wireless router.

              Devices can make a one-to-one connection or a group of serval devices can connect simultaneously. Wifi range and transfer speeds are significantly higher than those of Bluetooth. 

              Wifi direct supports 250m to 400m range. Wifi direct devices depend on versions. Wifi devices perform both roles as a client and an access point. Wifi direct relies on WPA2 security.

              Wi-fi direct is a method in which you can transfer data from one device to another without any wireless router. The founder of wifi has created wifi direct, ie. Wi-fi Alliance.

              When a device enters the Wi-Fi Direct host range, it can connect to it, and then gather setup information using a protected setup-style transfer.

              Wi-Fi Direct provides a wireless connection to peripherals. Wireless mice, keyboards, remote controls, headsets, speakers, displays, and many other functions can be connected with Wi-Fi Direct.

              Wi-fi direct is also being used in laptops, gaming consoles, smartphones, and televisions.
