What is Wi-Fi? Learn and Get How Does It Work?
Wi-Fi is an abbreviation for Wireless Fidelity, not to be confused with High Fidelity, which is a term used in the music industry. Wi-Fi is a technology that allows devices to connect to the internet wirelessly, without the use of cables or wires. This technology has become ubiquitous in modern life, with Wi-Fi networks available in homes, offices, schools, and public spaces. It's indeed remarkable how Wi-Fi enables real-time communication and data transfer, making it an essential part of our daily lives.
Wi-Fi is a type of wireless networking technology that allows devices to connect to the internet or communicate with each other without the use of cables or wires. It uses radio waves to transmit data between devices, and is commonly used in homes, businesses, and public hotspots. Wi-Fi operates on specific frequency bands, such as 2.
What's the Full Name of Wi-Fi? What Does It Stand for?
Wi-Fi is essentially a Wireless Local Area Network (WLAN), providing internet access to various IT devices such as mobile phones, computers, laptops, game consoles, and smart TVs, and is often referred to as Wireless Fidelity.
Wi-Fi is not the same as the internet, but rather a way to access it. Wi-Fi uses radio frequencies between 2GHz and 5GHz, unlike other devices like car stereos that use lower frequency ranges.
With Wi-Wi-Fi technology enables social media, Bluetooth, and real-time streaming, allowing you to connect to the internet via a wireless router and access it on your Wi-Fi-enabled device whenever you're connected.
The latest Wi-Wi-Fi 6 technology is the latest standard in wireless networking, offering several key features that improve performance and reliability. It provides faster speeds, increased capacity, and better performance in crowded environments, making it ideal for applications where many devices are connected.
- WPA 3- Wi-Fi Protected Access 3
- MU-MIMO- Mulitple-User, Multiple-In, Multiple-Out
- 1024-QAM – Quadrature Amplitude Modulation mode
- TWT- Target Wait Time
- BSS- Basic Service Set Coloring
- OFDMA- Orthogonal Frequency Division Multiple Access
Why Is It Called Wi-Fi?
Australian scientist John O'Sullivan and his team developed a radio wave identification and filtering tool to test a theory by Stephen Hawking, but their creation ultimately didn't help them achieve their goal.
John, who previously failed to find a way for computers to communicate wirelessly, later worked for CSIRO and, through some modified work, inadvertently invented Wi-Fi.
Ethernet and Wi-The history of Wi-Fi began with the creation of ALOHAnet, a wireless network developed in 1971. Later, in 1991, NCR Corporation and AT&T collaborated to develop WaveLAN, a precursor to Wi-Fi, to connect cash registers. This eventually led to the establishment of the IEEE 802.11 standard, which is now widely known as Wi-Fi.
Phil Belanger, a pioneer member of the Wi-Fi Alliance, admitted that the name 'Wi-Fi' was one of the options provided by the marketing agency, which was coined from the tag line "The Standard for Wireless Fidelity".
How Does Wi-Fi Work?
The system works like a two-way radio, transmitting data through an antenna, receiving and decoding the signal, and then sending the information to the internet.
Wi-Fi works by connecting a device to a wireless router or gateway, which serves as the access point, generating signals and allowing the device to access the internet.
Today, most routers are Wi-5G and 6 enabled and can work on two frequencies simultaneously, leading to faster speed and reliable signals.
How Is Wi-Fi Used?
Having known how Wi-Wi-Fi has revolutionized the way we live, work, and communicate. It has enabled the widespread adoption of the internet, making it possible for people to access information, connect with others, and conduct business from anywhere in the world.
- With smartphones, users can seamlessly roam between different Wi-Fi networks without being disconnected, providing a more mobile and flexible Wi-Fi experience compared to traditional networking designs.
- The device is useful for connecting hotspots and allowing users to stay connected, making it particularly useful during emergencies.
- It eliminates the need for wired connections, which can be time-consuming to set up and pose safety risks.
- Wi-Fi is being used to connect a wide range of products, including automotive goods, electronics, light bulbs, thermostats, and various other IoT devices.
- Smart TV users without a cable subscription can stream live TV and various channels without needing an antenna.
Final Words
Not many people know what Wi-Wi-Fi is a technology that allows devices to connect to the internet or communicate with each other without the use of cables or wires. It uses radio waves to transmit data and is commonly used in homes, businesses, and public hotspots. The term "Wi-Fi" is a play on the phrase "hi-fi," which refers to high-fidelity audio, and was coined by a company called Wi-Fi Alliance, which is a trade association that promotes the use of Wi-Fi technology.
