Hi Mi Fans!
In our daily life we use Wi-Fi to remain connected with internet. It is a very important to us to ensure our security while using Wi-Fi. Today we will know about the technology works behind this network method.

What is Wi-Fi?
Wi-Fi is a technology for wireless local area networking with devices based on the IEE 802.11 standards. Wi-Fi can be used on many devices such as mobile phones, pc, laptops, digital cameras, etc. When Wi-Fi compared to mobile hotspots Wi-Fi has a better range when compared to hotspots.Wi-Fi considers/uses 2.4 gigahertz (12 cm) UHF and 5 gigahertz (6 cm) SHF radio bands.

How does it work?
Wi-Fi network makes use of radio waves to transmit information across a network. The computer should include a wireless adapter that will translate data sent audio signal. This same signal will be transmitted, 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. As the wireless network works as a two-way traffic, the data received from the internet will also pass through the router to be coded into a radio signal.

Uses of WiFi
Wi-Fi has various uses other than just using it for internet service on your device. There are many wireless printers which work over Wi-Fi which means you can directly print directly through your phone or pc easily.

Wi-Fi can be used with the help of routers such as the Mi Router 3C. Setup the router and you are done. Just go to your phone, settings- Wi-Fi and connect to your Wi-Fi and enjoy services. The speed of your Wi-Fi depends upon the plan to which you have subscribed.

There are many popular brands like Xiaomi which is known for its performance. Many gadgets use Wi-Fi like Mi Wi-Fi speaker, 360 degree camera, Wi-Fi amplifiers, mouse use Wi-Fi  and work without wires.

You can use Mi Wi-Fi extender to extend the Wi-Fi network at your home. If you live at a big house then that might be helpful. You can also use IP camera through Wi-Fi such as the Mi IP camera.

Security is very important when it comes to internet. The most common types of wireless security are Wired Equivalent Protection (WEP) and Wi-Fi protected Access (WPA). For basic security you can apply that no one cannot connect to your Wi-Fi connection and use your internet access. WPA2 uses an encryption device that encrypts the network with a 256-bit key so that no one can hack your Wi-Fi network.

Security is being increasing over some time now. There are certain risks in which some hackers can hack your Wi-Fi connection and use it, so you need to be careful regarding that. If you have a Mi router then you can easily download a app from play store known as Mi Wi-Fi and scan QR code on router and you are good to go. Through the app you can apply password to your router and also check who is connected to your Wi-Fi and also remove someone from connecting to your Wi-Fi network if you don't want him to be connected and use your connection

Positive things about Wi-Fi
The main advantage of Wi-Fi you can work without many wires. This is a wireless connection that can merge together multiple devices. Wi-Fi network is particularly useful in cases where the wiring is not possible or even unacceptable. Wi-Fi is mostly used in halls or conferences where various devices can connect.

And almost all modern laptops, tablets, and some mobile phones have this feature. It is very convenient and allows you to connect to the internet almost anywhere, not just where the cables are laid. Today, you can access the network, for example, being in the park for a walk across the street or in an airport lounge. The main thing that was available near the point of Wi-Fi.

Negative Effects
Just like the wireless signals themselves, the EMFs can pass through walls. Most routers are not turned off at night, so you are exposed 24/7.You are not only exposed to EMFs from your own router. Did you ever search for a wireless signal and see not only your wireless network, but also your neighbor’s and the one from the business down the street? All of them emit EMFs. Increasingly, scientists and researchers are uncovering the health risks of EMFs. Depending on the level and the length of exposure, those risks can range from insomnia and headaches to tumors.

To conclude Wi-Fi is very useful to access the internet connection freely. The connectivity strength on Wi-Fi is better than on hotspot. Wi-Fi can be used for online gaming, streaming videos or music or working in internet.
