Hello steemit friends,
Today, almost everybody uses the internet and who has a smartphone, he must know about WiFi and also know how to use WiFi, but the use of WiFi is not only to use the internet but also Other data files can also be used to transfer such as if you want to send a file from your phone to another phone, then you Wi-Fi can be sent from WiFi before it was Bluetooth, we could transfer data from Bluetooth but Wi-Fi speed is more than Bluetooth and it works even longer.
The Wi-Fi is the most 2.4 Gigahertz (12 cm) UHF and 5 Gigahertz (6 cm) UHF SHF ISM radio band used in all countries, the signal of the Wi-Fi network is different in all the countries of the WiFi signal in Europe Compression is comparable because the Regulatory Authorities in the US allow Stronger Signals. So today we are going to know who and when did the invention of WiFi.
The full name of WiFi is Wireless Fidelity Wireless Fidelity and its invention is credited to John O Sullivan. But the real thing is that he used to work in CSIRO and his whole team invented the WiFi network (from 1992 to 1996), but John O Sullivan made some changes in it by Wi Fi-Speed up the speed even further and made the Wifi signal even better. That is why John O Sullivan is credited with the invention of WiFi.
In 1997, the first version of 802.11 Protocol was released, with speed of 2 Mbit / s. After that in 1999, it was updated to speed it to 11 Mbit / s. Many patents have access to WiFi and in April 2009 14 technology companies had given $ 1 billion to the CSIRO company instead of violating WiFi patents.
And thus gradually wifi made better, its speed was improved, today we have a WiFi router of 900 megabytes per second.
As we said WiFi's full name is Wireless Fidelity.
WiFi is used to connect two or more devices between each other. And with the help of WiFi, we can send any file to anyone. And in today's time, it is used to connect the Internet to our laptop and mobile. With the help of WiFi, we can send any file to anyone without internet. For this, you will find a lot of app on Google Play Store, with the help of which you can connect your phone to another phone. Any file can be sent between them.
Benefits of Wifi:
Wireless: - The biggest advantage of using WiFi is that you get rid of the wire if you want to use your laptop or mobile anywhere, with the help of WiFi, you can use the internet without wires.
Speed: If you talk about speed, the speed of WiFi is the highest speed so far, compared to Bluetooth, the speed of WiFi is multiplied and this speed works up to a long distance.
Longer Battery Life: Because of the strong signal of WiFi, it also reduces our battery news if we use the Internet from our mobile network, then the mobile battery is consuming too much, but if we help with WiFi If you use the internet, then our phone's battery runs very much.
