The Birth of WiFi: Understanding the Timeline
WiFi, short for “Wireless Fidelity,” is often used interchangeably with radio waves. The term “WiFi” itself was coined in 1999 by the WiFi Alliance, but the journey to create wireless networking technology dates back further to the late 20th century.
The Early Days of Wireless Communication
Before we pinpoint the year WiFi was created, we need to understand the groundwork laid by earlier technologies. The technology that would eventually evolve into WiFi grew from various wireless communication innovations.
In the early 1980s, researchers began exploring various forms of wireless communication. In 1985, the Federal Communications Commission (FCC) in the United States opened up the 2.4 GHz Industrial, Scientific, and Medical (ISM) radio bands for unlicensed use. This groundbreaking decision set the stage for the development of WiFi by enabling various wireless communication devices to operate without needing individual licensing.
The Foundation: IEEE 802.11 Standard
The first significant leap toward what we know as WiFi was the creation of the IEEE 802.11 standard, which is crucial to the history of WiFi technology. Established in 1997 by the Institute of Electrical and Electronics Engineers (IEEE), this standard defined how wireless local area networks (WLANs) operated.
The first version of the IEEE 802.11 standard could transmit data at a modest rate of just 2 Mbps, relying on Direct Sequence Spread Spectrum (DSSS) technology to send and receive signals wirelessly. This marked the dawn of wireless networking, though it would take several iterations before the technology would become prevalent.
The Official Launch of WiFi
The true inception of “WiFi” as we recognize it today occurred in 1999, with the formation of the WiFi Alliance and the introduction of enhancements to the IEEE 802.11 standard.
The first WiFi specification, known as 802.11b, provided a significant increase in data transmission speeds to up to 11 Mbps, allowing for broader application in consumer devices. This marked a burst of innovation, as various manufacturers embraced the new standard and began introducing WiFi-enabled devices into the market.
The Driving Forces Behind WiFi’s Popularity
The popularity of WiFi soared due to several factors that made it more appealing than traditional wired networks. Let’s explore these driving forces that shaped the adoption of this innovative technology.
