Ambient backscatter: Free energy harvesting from TV signals, to power a ubiquitous internet of things
2013-07-08 14:14:32| Extremetech
Researchers have created a new method of wireless networking that allows devices to communicate with each other without batteries or their own source of power. Dubbed "ambient backscatter," this method sucks power out of the air from TV and cellular transmissions, and then modulates this signal with its own data. These modulated signals are then picked up by other devices in the same ambient backscatter network. In theory, this could be the breakthrough to finally allow for a ubiquitous internet of things, where every location is blanketed with devices and sensors that communicate with each other, creating truly smart homes, offices, and cities.
