Man-Made Radio Wave ‘Bubble’ Could Protect Earth From Radiation | Smart News

Virtually nothing on Earth has escaped human influence, from the oceans to the atmosphere. But a new study suggests that human activity is also influencing the space around our planet; it’s above the space junk already swirling there. Very low frequency (VLF) emissions have created a planetary cocoon, shielding the planet from high-energy particle radiation, […]

Harnessing a wider spectrum of ambient radio waves for powerless communication with IoT devices

Most devices and sensors connected to the Internet of Things (IoT) rely on the transmission of radio waves to communicate, which requires power, which means batteries if mains power is not a option. A Disney Research team is looking to exploit a technique called ultra-wideband (UWB) ambient backscatter, which would allow devices to overlay their […]
