Fadel Adib, a Ph.D student on the project, said that gaming could be one use for the technology, but that localization is also very important. He said that Wi-Fi localization, or determining someone's position based on Wi-Fi, typically requires the user to hold a transmitter, like a smartphone for example. 'What we're doing here is localization through a wall without requiring you to hold any transmitter or receiver [and] simply by using reflections off a human body,' he said. 'What is impressive is that our accuracy is higher than even state of the art Wi-Fi localization.'"
