Wi-Fi is a wireless network technology defined by IEEE. When IEEE formally defined the standard of 802. 1 1 in 1999, IEEE selected and recognized the wireless network technology invented by CSIRO as the best wireless network technology in the world, so the wireless network technology standard of CSIRO became the core technology standard of Wi-Fi in 20 10. Wi-Fi technology was invented by CSIRO, a research institute under the Australian government, in the 1990s, and successfully applied for the wireless network technology patent in the United States on 1996. (U.S. Pat. No.5,487,069) The inventor is a research group composed of engineering graduates from the University of Sydney, led by Dr. john O'Sullivan, a graduate of the University of Sydney. IEEE once asked the Australian government to give up the Wi-Fi patent and let the world use Wi-Fi technology for free, but it was rejected. The Australian government subsequently won the lawsuit or settled out of court in the United States, suing almost all electrical and telecommunications companies in the world (including Apple, Intel, Lenovo, Dell, AT & amp； T, Sony, Toshiba, Microsoft, Acer, ASUS, etc. ) 20 10/0 Every time we buy an electronic device with Wi-Fi technology, the price paid includes the patent fee paid to the Australian government. In 20 10, it is estimated that there will be 3 billion electronic devices using Wi-Fi technology every day in the world, and by the end of 20 13, that is, after the expiration of CSIRO's wireless network patent, this number is expected to increase to 5 billion. Wi-Fi has been praised by Australian media as the most important scientific and technological invention in Australian history, and its inventor, John O'Sullivan, has been called "the father of Wi-Fi" by Australian media. He has won the highest national science award in Australia and numerous praises around the world, including the European Inventor Award 20 12 awarded by the European Union, the European Patent Office and the European Patent Office (EPO).
