Hello everyone, today I would like to talk about my interest of science. It’s Passive Wi-Fi .
Now, Wifi is the best for sent data, but it’s used battery so much. “we want to know that we can send data over Wifi using minimal battery?” Shyam Gollakota and his team from University of Washington told. Which is exactly what Passive Wi-fi do.We can use wi-fi with less energy than what is best now to 10000 times. They separate between digital and analogue in radio waves. Passive Wi-Fi then can reflect radio waves and create a new signal while it can absorb the energy to signal that it was being used as a cycle of power. In the future I think we can use Passive wi-fi without fear low battery.
