When you use a Wi-Fi network—at home, in the office or at the airport—you are using patented technology born of Australian astronomy.

Australia’s CSIRO created a technology that made the wireless LAN fast and robust. And their solution grew out of 50 years of radio astronomy and one man’s efforts to hear the faint radio whispers of exploding black holes.

Dr John O’Sullivan and his colleagues didn’t find the black holes. But they developed a way of cleaning up intergalactic radio wave distortion which became the key to fast, reliable Wi-Fi.
