If we were to ask someone to name a few Australian inventions, that would be the case. But there are: Australians have invented the black box of aircraft, the first pacemaker, the electric drill, and one of the most important tools of online communication: the wifi.
Wifi is now a global standard that everyone uses; there is no modern computer that can not connect to a wireless network. Today we know how much more comfortable our lives. But wifi was not a satisfying requirement for a crowd:
THE CONDUCTORS OF THE MINIATRIC BLOCK ARE TESTED TO DEVELOP A NEW DEVICE ONLY.
John O’Sullivan, an Australian physicist, knew Stephen Hawking’s theory of evaporation of black holes, where energy became a matter of substance and hence the mass of the black hole was reduced. O’Sullivan considered that these microscopic black holes could be detected with the appropriate frequency radio waves, so he began to develop a device to detect their existence.
He did not succeed.
The signals from the black holes were too weak to separate them from the cosmic microwave background noise that fills the whole universe. The signals examined by O’Sullivan came from too far, and they were intimidated by gases and nebulae; the resulting waveforms could not be used to prove the existence of Hawking radiation. O’Sullivan then started working with his colleagues – Terence Percy, Graham Daniels, Diet Ostry, and John Deane – to develop a tool to isolate weak signals.
THE EXERCISER HAS BEEN DISCOVERED.
In 1992, O’Sullivan worked at CSIRO where he was assigned the task of developing a wireless data transfer protocol for computer systems. He recalled that the previously developed radio astronomy device could also be used for the data transfer protocol. The device used to detect black holes was used to detect weak and confused radio signals in the darkest environment. O’Sullivan redesigned the system so that it can be used for data transfer between computers.

The wifi (or the so-called Wi-Fi) patent was registered in Australia in 1992 and then in the United States in 1996. A year later, the 802.11 protocol, which was also known today, provided two megabits per second transmission speed. The Wi-Fi Alliance was established in 1999, which is a wifi patented technology. This was a smart idea as the wifi was then happy and unhappy with it.
In April 2009, 14 technology companies agreed to pay a total of $ 1 billion in royalties to CSIRO for the use of wifi – which was officially recognized as a wifi Australian invention. Three years later, the Wi-Fi Alliance swept an additional 220 million for misuse of the patent. Although Hawking radiation has failed to detect, most of the Earth’s population would not even heat their dinner. However, they know how much more convenient to use the network cables without internet connection and therefore can not be grateful enough.
