Australia did not invent Wi-Fi. The technology behind Wi-Fi was actually developed in the 1990s by a team of researchers at the Commonwealth Scientific and Industrial Research Organisation ( #CSIRO) in #Australia, but it was not invented by Australians. The team, led by John O'Sullivan, was working on a project to detect black holes using #radio #waves, and they discovered a way to send and receive data over the airwaves using a series of complex #algorithms. This technology was eventually adapted and commercialized by other companies to create the Wi-Fi technology that we know today. So, while Australia played an important role in the development of Wi-Fi, it was not the country where the technology was originally invented.
