In the modern era, wifi has become as essential as electricity. It powers our communication, entertains us, and keeps our businesses running. But have you ever paused to wonder who invented wifi? This article explores the origins of wifi. We also look at its operational principles, the brilliant minds behind its invention, and how modern solutions like Routie guest can transform simple wifi connectivity into a tool for business growth.

What Is Wifi?

Wifi, short for wireless fidelity, is a technology that uses radio waves to provide network connectivity. A wifi connection is established using a wireless adapter to create hotspots, which are networked areas in the vicinity of a wireless router. Wifi technology enables computers, smartphones, and other devices to communicate over a wireless signal, eliminating the need for wired connections between devices.

How Wifi Works

To appreciate the genius of wifi, it’s important to understand how wifi works. Wifi converts data into a radio signal through a wireless router. This signal is then transmitted using radio waves to a device equipped with a wifi chip. This enables the device to connect to the internet without the need for physical cables.

The process involves several key components. The wireless router acts as the broadcast point. The wifi chip is embedded in our devices and makes the connection. The frequency bands of 2.4 GHz or 5 GHz is the signal across which the wifi operates. These components work together to ensure efficient wireless communication.

The Inventors of Wifi

Who Invented Wifi

The question of “who invented Wifi” does not point to a single inventor but rather a group of engineers. It is the culmination of years of research and development by many contributors around the globe,  who contributed to the development of wireless networking technology. 

Among them are Dr. John O’Sullivan and his team at the Commonwealth Scientific and Industrial Research Organisation (CSIRO) in Australia, who played a pivotal role. In the 1990s, a key patent was developed for wifi as “a method for radio communication” that solved the problem of radio-wave interference. This was fundamental for the wifi we use today.

Vic Hayes, often referred to as the “Father of Wifi,” chaired the IEEE committee that created the 802.11 standards in 1997. These standards are what wifi networks use today to ensure devices can communicate with each other.

Additionally, companies like NCR Corporation and AT&T also played a significant role in the early development of the technology, particularly in creating and commercializing the WaveLAN product, an early version of wifi.
