What is a Wifi? Everything you need to know about Wifi

What is a Wifi? Ever came across your mind, the wifi connection we use everyday, what exactly it is, whats the exact use of it, how does it impact of lives and how does it connect us to the whole world. Don’t worry i’m here to answer all your questions. Do read the whole article and know everything about wifi.

What is a Wifi?

Wi-Fi is short for wireless fidelity. Wi-F is a set of wireless network protocols based on the IEEE 802.11 family of standards that allows neighbouring digital devices to exchange data through radio waves. These are the most widely used computer networks in the world, used in homes and small offices to link desktop and laptop computers, tablets, smartphones, smart TVs, printers, and smart speakers to a wireless router to connect them to the Internet, and in public places like coffee shops, hotels, libraries, and airports to provide Internet access for mobile devices. In simple words Wi-Fi is a technology that lets computers, tablets, smartphones, and other devices connect to the internet wirelessly. Wi-Fi is the radio signal a wireless router sends to a nearby device, which turns it into usable data. I hope you understood the meaning.

Who created Wifi?

Considering Wi-many Fi’s components, pinpointing a single inventor is challenging.

First, research the 802.11 radio frequency standards used to transmit Wi-Fi signals. Second, examine the equipment used to broadcast and receive Wi-Fi signals. Wi-Fi has several patents, but one jumps out.

Vic Hayes, who headed the IEEE group that produced the 802.11 specifications in 1997, is nicknamed the “father of Wi-Fi.” Hayes created Wi-Fi standards before the public knew about them. In 1997, 802.11 was created. 802.11 specifications later improved network bandwidth. 802.11a, 802.11b, 802.11g, 802.11n, etc. The letters indicate this. As a consumer, the newest version performs best. All new equipment should be compatible with this version.

All the generations of Wifi

Multiple Wi-Fi versions are common. Devices need a common Wi-Fi version to communicate. Versions vary in radio wavebands, radio bandwidth, maximum data speeds, and other features. Multiple antennas provide faster speeds and less interference in certain versions.

Historically, equipment identified Wi-Fi versions by IEEE standard. Wi-Fi Alliance simplified generational numbering in 2018 to designate Wi-Fi 4 (802.11n), Wi-Fi 5 (802.11ac), and Wi-Fi 6 equipment (802.11ax). These generations are backward-compatible. The alliance says the linked user interface may show generational level 4, 5, or 6 and signal strength.

The list of most important versions of Wi-Fi is: 802.11a, 802.11b, 802.11g, 802.11n (Wi-Fi 4), 802.11h, 802.11i, 802.11-2007, 802.11-2012, 802.11ac (Wi-Fi 5), 802.11ad, 802.11af, 802.11-2016, 802.11ah, 802.11ai, 802.11aj, 802.11aq, 802.11ax (Wi-Fi 6),

Pros and Cons of Wifi


  • Efficiency: Information is sent quickly and easily. Businesses may, for instance, give price quotations to customers from distant locations.
  • Flexibility: When connecting to a wireless network, end users are not constrained to a single physical location. This makes it possible to utilise space in an office environment more effectively.
  • Cost Effectiveness: Installing wireless networks in an office setting is comparatively inexpensive. Additionally, it gives users more options when choosing computer hardware.
  • Accessibility: In public places like a coffee shop, bookstore, hotel, or restaurant, wi-fi is very common. It is simple to connect to the internet thanks to its strong signal.


  • Security: Hackers target wireless networks. Unauthorized access to your network might lead to critical data theft. Set a strong wifi password. Encourage staff to utilise HTTPS websites and SSL with internet-connected apps. After using Wi-Fi, turn it off.
  • Coverage: Wireless connection is restricted (often from 50-300 ft). Know the wireless signal’s range. It’s irritating to lose internet because you’re out of range.
  • Speed: Most wired networks have slower data transfer. Wired networks have more capacity and can handle more network traffic.

Now you know everything about the Wifi, make sure you make a good use of it.
