The world as we know it would not be the same without WiFi. This revolutionary technology has enabled us to stay connected, access information, and conduct business from anywhere, at any time. But have you ever wondered when WiFi was made public? In this article, we’ll take a journey through the history of WiFi, exploring its humble beginnings, development, and eventual public release.
The Early Days of WiFi
The concept of wireless networking dates back to the 1960s, when the United States Department of Defense’s Advanced Research Projects Agency (ARPA) funded a project to create a network of computers that could communicate with each other wirelessly. This project, known as ARPANET, was the precursor to the modern-day internet.
In the 1980s, a team of researchers at Nokia developed a wireless local area network (WLAN) technology that used radio waves to transmit data between devices. This technology, known as WLAN, was the first to use the 2.4 GHz frequency band, which would later become the standard for WiFi.
The Birth of WiFi
Fast-forward to the 1990s, when a team of engineers at Nokia, led by Vic Hayes, began working on a new wireless technology that would eventually become WiFi. Hayes, who is often referred to as the “Father of WiFi,” was instrumental in developing the first WiFi standard, known as IEEE 802.11.
In 1997, the IEEE (Institute of Electrical and Electronics Engineers) established a committee to develop a wireless local area network (WLAN) standard. This committee, known as the 802.11 working group, was tasked with creating a standard that would enable devices to communicate with each other wirelessly.
The First WiFi Standard: IEEE 802.11
On June 26, 1997, the IEEE 802.11 working group published the first WiFi standard, known as IEEE 802.11-1997. This standard specified the use of the 2.4 GHz frequency band and supported data transfer rates of up to 2 Mbps.
The first WiFi products were released in 1999, and were met with moderate success. However, these early WiFi devices were limited in their range and data transfer speeds, and were often plagued by interference from other devices.
The Evolution of WiFi
Over the next few years, the 802.11 working group continued to develop and refine the WiFi standard. In 1999, the IEEE published the IEEE 802.11b standard, which increased data transfer speeds to up to 11 Mbps.
In 2001, the IEEE published the IEEE 802.11a standard, which used the 5 GHz frequency band and supported data transfer speeds of up to 54 Mbps. The IEEE 802.11a standard was later followed by the IEEE 802.11g standard, which used the 2.4 GHz frequency band and supported data transfer speeds of up to 54 Mbps.
WiFi Becomes Public
It wasn’t until 2003 that WiFi started to gain widespread acceptance and become public. In 2003, the Wi-Fi Alliance, a trade organization that promotes WiFi technology, was formed.
The Wi-Fi Alliance was instrumental in promoting WiFi technology and ensuring that devices from different manufacturers were compatible with each other. The organization developed a certification program, which tested devices for compliance with the WiFi standard and ensured that they were interoperable.
The Rise of Public WiFi
In the early 2000s, public WiFi hotspots began to appear in coffee shops, airports, and hotels. These hotspots allowed users to access the internet from their laptops and mobile devices, and marked the beginning of the public WiFi era.
The first public WiFi hotspot was launched in 2000 by a company called MobileStar, in a Starbucks coffee shop in San Francisco. This hotspot was followed by others, and soon public WiFi hotspots were appearing in cities around the world.

What is WiFi and how does it work?
WiFi 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 works by transmitting data through radio waves at a specific frequency, typically in the 2.4 gigahertz or 5 gigahertz range. This allows devices such as laptops, smartphones, and tablets to connect to a network and access online content.
WiFi networks use a device called an access point, which is typically a router or hotspot, to transmit the signal. The access point is connected to a wired network, such as a broadband internet connection, and it converts the wired signal into a wireless signal that can be received by devices with WiFi capabilities. Devices then use WiFi adapters to receive and decode the signal, allowing them to connect to the network and access online content.
Who invented WiFi and why?
WiFi was invented by a team of researchers at Nokia in the 1990s, led by engineer Vic Hayes. They were tasked with developing a wireless networking technology that could provide high-speed internet access without the need for cables. The team drew inspiration from earlier wireless technologies, such as wireless local area networks (WLANs) and radio frequency identification (RFID) systems.
The invention of WiFi was driven by the growing need for wireless connectivity in the 1990s. As the internet became more widespread, people began to look for ways to access it without being tied to a physical cable. WiFi was seen as a way to provide fast, reliable, and convenient internet access, which would revolutionize the way people worked, communicated, and accessed information.
When did WiFi become publicly available?
WiFi became publicly available in 1999, when the WiFi Alliance, a consortium of technology companies, launched the first WiFi certified products. This marked the beginning of widespread adoption of WiFi technology, as devices and networks that met the WiFi certification standards became available to the public.
The widespread adoption of WiFi was driven by the growing demand for wireless connectivity and the need for a standardized technology. The WiFi Alliance played a key role in promoting the technology and ensuring that devices and networks from different manufacturers were compatible with each other.
