New technology promises to deliver WiFi battery
Future devices "Internet of things" will not work on batteries, and give power literally in the air. Appropriate technology was developed at the University of Washington in the United States. Here a group of engineers has developed a technology called WiFi Backscatter, which is a communication system that applies radio waves as a power source. devices with support for WiFi Backscatter can use electricity from the radio frequency signal, for example radio waves of television signals, cellular or WiFi-station transmitters.
Technology specially converts the RF signals into electricity. In the article the Washington experts said that their technology potentially allows you to connect to the internet "billions of IoT-devices", avoiding the production of complex solutions, as well as removing the problem of battery life from the regular battery. "IT industry says about connecting" more than one billion devices " network. However, the problem of constant charging these devices may negate the benefits of their work, "- says co-author Bruce Kellogg development.
"Traditional WiFi-devices is extremely demanding to electricity, but WiFi Backscatter can reduce the dependence on batteries." In the university have developed a special low-power energy-tag with integrated antennas and conductive components, which can be connected to a variety of devices. Tags integrate with laptops, smartphones or tablets. In addition, the tags track WiFi-signals traveling between the routers and switches. now at the University create a commercial company for market promotion of technology.
