Who Invented Wi-Fi First: The Truth About the Birth of Wireless Internet

Wireless internet has become such a common part of our lives that it is difficult to imagine a world without it. Wi-FiWe connect smartphones, laptops, smart speakers, and even refrigerators wirelessly—but who was behind this revolution? The question "who invented Wi-Fi" seems simple, but the answer is as tangled as a web of radio waves.

Unlike many technologies, Wi-Fi There is no single "founding father." It is the result of decades of research, patent wars, and collaboration between scientists from around the world. In this article, we will examine:

• 🔬 Who first proposed the concept of wireless data transmission (spoiler: it was long before the 1990s)
• 📡 As standard IEEE 802.11 became the basis of modern Wi-Fi
• 💡 Why an Australian scientific organization CSIRO sued Apple, Microsoft, and HP for billions of dollars
• 📱 How Wi-Fi has evolved: from 2 Mbps in 1997 to 10 Gbps in Wi-Fi 7

You'll be surprised to learn that the first prototype of a wireless network appeared back in 1971—20 years before the commercial launch of Wi-Fi. And the patent that formed the basis of modern routers was registered... to solve a completely different problem. Ready to dig into the details?

1. Wi-Fi Predecessors: From Hertz to Alohanet

The idea of ​​transmitting data "over the air" arose long before the first computers appeared. It all began with discoveries in the field electromagnetic waves:

• 📻 1888 — Heinrich Hertz experimentally proved the existence of electromagnetic waves (hence the unit of measurement of frequency — hertz).
• 📡 1895 Alexander Popov and Guglielmo Marconi independently invented radio. It was the first wireless transmission of a signal over a long distance.
• 🛩️ 1940s — Radar systems during World War II laid the foundation for future microwave technologies.

But the real breakthrough came in the 1970s, when scientists began looking for a way to connect computers wirelessly. The first practical implementation was the network AlohaNET, created in In 1971 in the Hawaiian Islands. It was developed by Professor Norman Abramson of the University of Hawaii for communication between computers on different islands. The data transfer speed was only 9.6 kbps, but the principles of operation AlohaNET later formed the basis Ethernet and Wi-Fi.

⚠️ Note: Many sources mistakenly attribute the invention of Wi-Fi to the project AlohaNET, but this is incorrect. The network used radio waves to transmit data, but was not a precursor to modern standards. 802.11Her main achievement is the development of the protocol. carrier sense multiple access (CSMA), which was later adapted for Wi-Fi.

In the same year 1971 the company Xerox in his research center Palo Alto Research Center (PARC) began experiments with wireless communication between computers. However, these developments remained closed to the general public for another two decades.

2. CSIRO Patent: Australia's Footprint in Wi-Fi History

If you ask an Australian who invented Wi-Fi, he will proudly answer: “Of course, we did!” - and he will be partially right. In 1992 scientists from the state scientific agency CSIRO (Commonwealth Scientific and Industrial Research Organisation) registered a patent under number US5487069 on the technology that later became key to Wi-Fi.

A group led by Dr. John O'Sullivan was working on a problem far removed from the internet: they were trying to detect mini-flares from black holes using radio telescopes. To do this, they needed to eliminate the interference caused by radio waves reflecting off surfaces. O'Sullivan's solution was using the fast Fourier transform (FFT) for signal processing — turned out to be revolutionary.

This technology has made it possible to:

• 📶 Significantly increase the data transfer rate over the radio channel.
• 🔄 Reduce interference in noisy environments (e.g. offices with many devices).
• 💻 Become the basis for the standard IEEE 802.11a, which is used in most Wi-Fi devices today.

However, the CSIRO patent was not immediately noticed by equipment manufacturers. Only in 2000s The organization filed lawsuits against companies using their technology without a license. Among the defendants were giants like Apple, Microsoft, HP And IntelAs a result of the legal proceedings, CSIRO received more $1 billion in compensation — one of the largest amounts in the history of patent disputes.

3. IEEE 802.11 Standard: How Wi-Fi Became Massive

While the Australians were litigating, the real implementation of Wi-Fi was happening thanks to the efforts of Institute of Electrical and Electronics Engineers (IEEE). IN In 1997 the first wireless communication standard was ratified - IEEE 802.11, which marked the beginning of the Wi-Fi era.

Key milestones:

Fun fact: The term "Wi-Fi" was coined by a marketing company. Interbrand commissioned by the alliance Wi-Fi Alliance V In 1999It has nothing to do with "Wireless Fidelity"—it's just a play on words reminiscent of "Hi-Fi." The Wi-Fi logo, with its wave-shaped symbol, was designed by Philips.

First devices with support 802.11b appeared on sale in In 1999Among the pioneers:

• 🖥️ Apple AirPort — Wireless base for Mac (1999)
• 📡 Lucent Technologies Orinoco — one of the first Wi-Fi cards for PCs
• 📱 Nokia 7110 — the first phone with WLAN support (2000)

⚠️ Please note: Wi-Fi standards continue to evolve. The following are relevant today: 802.11ax (Wi-Fi 6/6E) and 802.11be (Wi-Fi 7), but support depends on your hardware. Before purchasing a router, check compatibility with your devices.

4. Vic Hayes: The Man Who "Invented" Wi-Fi for the Masses

If we talk about a specific person who can be called the “father of Wi-Fi”, then most often they mention Vika Hayes (Vic Hayes). A Dutch engineer who worked for the company NCR Corporation, headed the standardization group IEEE 802.11 With 1990 to 2003.

Hayes and his team faced a serious problem: how to make devices from different manufacturers “understand” each other? Their solution was Unified Wireless Protocol — became the basis for all modern Wi-Fi networks. In interviews, Hayes often repeated:

"We didn't invent wireless. We made it compatible and accessible to everyone."

For his services, Vic Hayes received the nickname "Father of Wi-Fi". IN In 2003 he was awarded a medal IEEE Alexander Graham Bell Medal — one of the highest awards in telecommunications. Today, Hayes continues to work as a consultant and speaks at conferences dedicated to the future of wireless technologies.

A curious episode: in In 2012 Hayes visited Australia and met with the CSIRO team. Despite the patent disputes, he publicly acknowledged the Australian scientists' contributions to the technology's development, calling their work "critical to improving the speed and reliability of Wi-Fi."

5. Myths about the invention of Wi-Fi: what's wrong with popular versions

There are many myths surrounding the history of Wi-Fi. Let's address the most common ones:

Myth 1: "Wi-Fi was invented by Apple."

Apple actually released one of the first mass-market Wi-Fi products – a base station. AirPort V In 1999However, this was after the standard had already been adopted. 802.11bThe company played an important role in popularizing the technology, but not in creating it.

Myth 2: "Wi-Fi was invented for the military."

While the military did use wireless communications (such as radar), the standard 802.11 was developed for civilian purposes. The exception is technology frequency hopping (frequency hopping), patented by the actress Hedy Lamarr V In 1942 to guide torpedoes. This principle was later used in Bluetooth and earlier versions of Wi-Fi.

Myth 3: "Cisco made the first Wi-Fi router."

Company Cisco was among the pioneers, but released the first commercial router 3Com V In 1998 - model 3Com AirConnectCisco presented its solution. Aironet only in In 1999.

Another popular misconception is:5G will replace Wi-Fi"In fact, these technologies complement each other. 5G provides mobile internet access on the street, and Wi-Fi remains the optimal solution for home and office networks due to its low cost and high speed.

Why is Hedy Lamarr called the "Mother of Wi-Fi"?

Hedy Lamarr, a famous Hollywood actress of the 1940s, and composer George Antheil invented a secret communications system for torpedo guidance using hopping radio frequencies. Their patent, No. 2,292,387 (1942), formed the basis of the technology. spread spectrum, which was later used in Wi-Fi and Bluetooth. Lamarr received posthumous recognition for her contributions to wireless technology, and in 2014 she was inducted into the National Inventors Hall of Fame.

6. Wi-Fi Evolution: From 2 Mbps to 10 Gbps

Since the first standard appeared 802.11 V In 1997 Wi-Fi speed has increased in 5000 times. Today Wi-Fi 7 (standard 802.11be) promises speeds up to 10 Gbps - this is enough for the simultaneous transmission of several video streams in 8K or download a movie in a few seconds.

Key development milestones:

• 🐢 1997 — 802.11: 2 Mbps, 2.4 GHz only, incompatibility between devices of different brands.
• 🚶 1999 — 802.11b (Wi-Fi 1): 11 Mbps, beginning of mass distribution.
• 🏃 2009 — 802.11n (Wi-Fi 4): 600 Mbps, MIMO support (multiple antennas).
• 🚀 2013 — 802.11ac (Wi-Fi 5): 1.3 Gbps, operating at 5 GHz.
• 🌌 2019 — 802.11ax (Wi-Fi 6): 9.6 Gbps, best performance in dense networks (stadiums, airports).
• ⚡ 2026 — 802.11be (Wi-Fi 7): up to 10 Gbps, latency less than 5 ms (critical for VR/AR).

Interesting fact: standard 802.11ad (2012) used frequency 60 GHz and provided speed up to 7 Gbps, but due to its short range (only a few meters), it was not widely used. Its successor is 802.11ay — used in corporate networks and for connecting VR headsets.

Today, Wi-Fi is used for more than just the internet. It powers:

• 🎮 Wireless Game Controllers (Nintendo Switch, PlayStation).
• 🔊 Smart speakers (Amazon Echo, Google Home).
• 💡 Smart home systems (Philips Hue, Samsung SmartThings).
• 🚗 Driverless cars (for communication with infrastructure).

7. The Future of Wi-Fi: What awaits us in 10 years?

Experts predict that by In 2030 Wi-Fi will become even more integrated into our lives. Here are a few trends:

1. Wi-Fi Sensors: Routers will not only distribute the Internet, but also serve as motion, temperature, and humidity sensors by analyzing reflected radio waves.
2. Terahertz networks: experiments with frequencies 300 GHz - 3 THz They promise speeds up to 100 Gbps, but for now these are laboratory developments.
3. Energy-efficient Wi-Fi: New protocols will reduce the energy consumption of IoT (Internet of Things) devices by 10 times.
4. Quantum Wi-FiChinese scientists have already conducted the first experiments in transmitting data using quantum entanglement, which will make communications impossible to hack.

One of the most ambitious projects is Wi-Fi HaLow (standard 802.11ah). It operates on a frequency 900 MHz and is designed for low-power devices (such as sensors in smart cities). The communication range reaches 1 km, and the batteries in such devices can last up to 10 years.

At the same time, competition from other technologies is growing:

• 📶 5G/6G — next-generation mobile networks.
• 🌐 Li-Fi — data transmission via light waves (speed up to 224 Gbit/s, but requires line of sight).
• 🛰️ Satellite Internet (Starlink, OneWeb).

However, experts agree that Wi-Fi will remain the dominant technology for local area networks at least until 2040 due to its flexibility, low cost and ease of deployment.

FAQ: Frequently asked questions about creating Wi-Fi

Is it true that Wi-Fi is harmful to health?

The harm of Wi-Fi has not been scientifically proven. The radiation power of a home router is hundreds of times lower than that of a mobile phone. The World Health Organization (WHO) classifies radiofrequency fields as "possibly carcinogenic" (Group 2B), but pickled vegetables and talc fall into this category as well. The risk is minimal if safety precautions are followed: don't place the router near your bed and use it at least 1 meter away.

Why is Wi-Fi called "Wi-Fi" and not "Du-W-I-F-I"?

The term "Wi-Fi" was coined by marketers as a play on words reminiscent of "Hi-Fi" (high-quality audio). It's not officially an acronym, although many mistakenly interpret it as "Wireless Fidelity." The developers of the standard themselves 802.11 Initially, the term "WLAN" (Wireless Local Area Network) was used.

Will we be able to live without Wi-Fi in 2026?

Technically yes, but it will greatly limit your options. Alternatives:

• 📡 Mobile Internet (4G/5G) - Suitable for smartphones, but expensive for permanent use on a PC.
• 🔌 Wired Ethernet — more reliable and faster, but requires cable laying.
• 💡 Powerline — Internet transmission via electrical wiring (speed up to 1 Gbit/s, but sensitive to interference).
• 📶 Li-Fi — experimental technology, requires special equipment.

For most tasks (streaming video, online gaming, smart home), Wi-Fi remains the optimal solution.
