Fact Of The Post

Stephen Hawking inspired John O’Sullivan to accidentally give us all Wi-Fi.

Facts And History Related To WiFi Invention

💪💪💪 Let's Start Reading 😤😤😤

He set out to find them and prove the theory correct.

An Australian scientist named John O’Sullivan was inspired by Stephen Hawking’s theory of evaporating black holes and their subsequent radio waves.

Whilst doing so, he found that these weak signals were hard to distinguish from the louder background radio noise of the entire universe.

Fast forward to 1992…

John O’Sullivan was working for the CSIRO and was tasked with finding a way for computers to communicate without wires – a wireless system of some type.

Remembering his previous research into black holes and the tools he’d created to identify the black hole radio waves wirelessly, O’Sullivan went back to the tool he’d previously made.

Using the mathematical formula of this device he was able to modify and tweak it, using this as a basis for Wi-Fi to search out weak and fuzzy radio signals in the noisiest of environments.

This re-purposed and unintentional invention earned the CSIRO roughly $1 billion in royalties.

O’Sullivan patented it in his native country first in 1992, then later in the U.S. in 1996.

So, thank you to Stephen Hawking for inspiring John O’Sullivan to accidentally give us all Wi-Fi!

What were the signals?

These signals had traveled such vast distances and were so small and distorted by the gas and dust of space they had passed through.

This meant their waveform had altered from a sharp and easily identifiable spike to a flattened curve.

It was because of this that O’Sullivan and his research contemporaries got to work on creating a tool that could identify and filter specific radio waves.

After lots of hard work, O’Sullivan and a colleague were able to create a tool based on a mathematical formula that would help them find these waves, blocking out the extraneous radio signals to identify the useful ones.

However, they were unsuccessful in finding a black hole’s radio waves.

What is Wi-Fi short for?

Ans: Now wireless networking technology can be found in our watches, phones, televisions, and smart speakers. We know what it means, but what does Wi-Fi stand for? You may have read or educated guess that Wi-Fi stands for “wireless fidelity” just as Hi-Fi stands for “high fidelity”.

What is full-form WiFi?

Ans: Wireless Fidelity

IEEE is a separate, but related, organization and its website have stated: "WiFi is a short name for Wireless Fidelity". Interbrand also created the Wi-Fi logo.

What app gives free WiFi?

Ans: Avast Wi-Fi Finder is a free application for Android, which lets you find free WiFi networks around you. It features regular updates that keep you alerted to the latest information about WiFi hotspots nearby. When you launch the application for the first time, your device needs to be connected to the Internet.

Who actually invented WiFi?

Ans:1.John O'Sullivan
2. Terence Percival
3. Diethelm Ostry
4. John Deane
5. Graham Daniels

What are the different types of WiFi?

Ans: The five Wi-Fi technologies are A, B, G, N, and AC. B and G use the 2.4 GHz frequency; A and AC use the 5 GHz frequency, and N uses both 2.4 and 5 GHz frequencies. Your choice for your home or business will come down to three: Wireless G, N, or AC.
