The technology of energy transfer via Wi-Fi
Radio waves WiFi-signal can be made to transmit not only information, but also energy. The site tells about the amazing razrabotke.Rasprostranenie latest wireless data transmission has committed a small revolution in our lives. Now we connect to the network everywhere, and stay in touch almost always, and on the mass of clutter escaped. I stayed next bastion - a charge - and it looks like he is about to collapse. Engineers of the University of Washington reported the development of technology PoWiFi, that allows you to pass through the air and more energy
«We are for the first time able to show that you can use WiFi to power sensors and other devices, - says one of the authors of development WAYS Talley. - < A system that can simultaneously work as a WiFi-router and as a source of power; wireless signal quality during charging wirelessly not impaired. " Present technology is planned in December 2015 at a conference in Germany CoNEXT.
Unfortunately, for charging smartphones or laptops question. PoWiFi intended for devices that consume very little power - a level comparable to the peak power capacity of radio waves WiFi-signal. However, this includes not only the abstract "sensors", but it is clear to all bracelets and fitness trackers webcam.
For this purpose an ordinary WiFi-router is upgraded so that from time to time he sends the data packets are not, and energy, using unoccupied information transmission channels. Made prototype proved effective enough to without problems (without wires) to feed a small video camera VGA to a distance of 5 m. A charging fitness tracker Jawbone Up24 41% it took him about 2, 5 hours. At the same time the quality of the network channel Communication is not affected.
It is hoped that the authors will find a way to improve the development and transfer of energy is more - so that was enough even for a smartphone.
