But have you ever wondered when Wi-Fi was first used? Let’s take a journey back in time to unravel the mystery of Wi-Fi’s origins.
The Early Days of Wireless Networking
The concept of wireless networking dates back to the 1960s, when the first wireless local area network (WLAN) was developed. This pioneering technology was the result of a collaboration between the University of Hawaii and the United States Department of Defense. The goal was to create a wireless network that could connect computers and devices across a small geographic area.
In the 1980s, the Federal Communications Commission (FCC) allocated a portion of the radio spectrum for wireless communication technologies. This paved the way for the development of wireless local area networks (WLANs) and wireless personal area networks (WPANs).
The Birth of Wi-Fi
Fast forward to the 1990s, when a group of engineers at Nokia, led by Victor Hayes, began working on a new wireless technology. This technology, later known as Wi-Fi, was designed to provide high-speed wireless connectivity to devices. In 1990, Hayes formed the Wireless LAN Working Group, which aimed to develop a standardized wireless technology.
In 1997, the Institute of Electrical and Electronics Engineers (IEEE) published the 802.11 standard, which outlined the specifications for wireless local area networks (WLANs). This standard was the foundation of Wi-Fi as we know it today.
The First Wi-Fi Devices
The first Wi-Fi devices were developed by Nokia in 1991. These devices, known as wireless local area network (WLAN) adapters, allowed computers to connect to a wireless network. However, these early devices were bulky and expensive, making them inaccessible to the average consumer.
It wasn’t until 1999 that the first Wi-Fi-enabled devices for consumer use were released. The first Wi-Fi-enabled laptop was the IBM ThinkPad 600E, which was released in 1999.
