Wi-Fi is said to have been invented by Victor Hayes, but like most ideas, it was made by more than one person.
This piece talks about how Wi-Fi came to be and talks about the people and technologies that made it possible. It also looks at how Wi-Fi has changed and grown over time.
The Invention of Wi-Fi
Wi-Fi isn’t what it is today because of just one person. It’s not true and it’s not fair to say that one person invented it.
Between the technology that makes wireless communication possible and the hardware that plays an equally important part, there are a few people who could be seen as the glue that held everything together and pushed for improvements over the years to make Wi-Fi what it is today. When we think about the people who made Wi-Fi, all of these people are just as important.
As was said above, Victor “Vic” Hayes is often called the “Father of Wi-Fi.” Vic led the IEEE 802.11 Standards Working Group for Wireless Local Area Networks as its head. IEEE is the group that decides how wireless devices should be made and how they should interact with each other.
Vic’s part was important, but it doesn’t show everything. Wi-Fi is more than just the rules and norms that govern it.
For example, actress Hedy Lamarr and composer George Antheil came up with a radio guidance device during World War 2. It used technology called “frequency-hopping,” which moved radio messages to different frequencies to stop them from being jammed. Even though this isn’t Wi-Fi, their ideas were used to make Wi-Fi.
But even in that case, many other people were working on similar projects, some of them even before that time. Guglielmo Marconi, an Italian inventor, tried out frequency-selective reception in 1899 to cut down on radio disturbance. Nikola Tesla and others worked on frequency-hopping technology that was similar to this.
In 1971, the University of Hawaii made the first public test of a wireless packet data network. This was done after researchers looked into whether radio waves could be used to connect computers. The networking system, called ALOHAnet, worked by using ultra-high frequency (UHF) to connect seven computers on four islands to a central computer so they could talk to each other wirelessly.
About a decade later, changes in the law in the US made it possible for Wi-Fi networks to use bands that had been blocked.
In the early 1990s, John O’Sullivan, an Australian engineer, helped create a way to reduce radio signal interference in computer networking that is still used in Wi-Fi today.
In 2000, Radiata made a chipset that worked with 802.11a and could send data as fast as 54 Mbps. Since then, more 802.11 standards, such as 802.11b/g/n, 802.11ac, and 802.11ax (Wi-Fi 6), have been made.
Wi-Fi was made by many people over many years. This change is still happening now.
Wi-Fi is a system for wireless networking that lets devices talk to each other over radio waves. Wi-Fi gadgets can send and receive information wirelessly, without cables.
A laptop is a good example of a device that can connect to Wi-Fi. Still, a Wi-Fi network can be used to connect many other devices, such as TVs, tablets, smartphones, freezers, and washing machines.
A computer network is mostly made up of the router. Your internet service provider hooks up your computer to the internet. The router then connects all the gadgets in your home to the internet. A Wi-Fi router can do this without wires.
WLAN, which stands for “wireless local area network,” is another name for Wi-Fi. It uses the 802.11 IEEE network standard as its foundation. The words 5 GHz and 2.4 GHz, bandwidth, and megabits (Mb) are often used when talking about Wi-Fi.
Most of us are used to being able to use Wi-Fi. So much so that it’s no longer a thought. Wi-Fi is set up and working in a lot of homes and companies. There are also a lot of Wi-Fi hotspots in restaurants, parks, and hotels. Our new devices have Wi-Fi turned on and are ready to connect to our home networks right out of the box.
The normal person who uses the internet might think that this technology is complete because it is so common and easy to use, but it is not.
The number of people who want to use the internet is always going up, and there are always new security problems to deal with, like getting rid of WEP.
