The object
John O’Sullivan led the CSIRO team that developed a multipath-resistant wireless-LAN technology using fast Fourier-transform techniques. It made high-speed Wi-Fi radios reliable in reflective indoor environments, and its chipset and protocol work became embedded in routers, phones, cameras and other connected hardware.
