Power Over WiFi‬ (PoWiFi)

YOUR WIRELESS INTERNET COULD POWER YOUR FUTURE DEVICES


RESEARCHERS HAVE DEVELOPED THE VERY FIRST POWER SUPPLY OVER A WI-FI SYSTEM. PoWiFi iS A SYSTEM WHICH'LL HELP CHARGE YOUR DEVICES WHILE CONNECTED TO WI-FI.




Researchers at the University of Washington have developed the very first power supply over a Wi-Fi system. PoWifi or Power Over Wi-Fi is a system which in simple terms will help charge your electronic devices, while connected to a Wi-Fi network. With a large Wi-Fi infrastructure already in place, wireless power delivery can be ensured in any place that provides a stable Wi-Fi connection.



How does it Work ?



No More Low Battery Crises‬.



Wi-Fi routers are capable of transmitting power. PoWiFi forces your wireless router to send out a constant 1W signal, which can be captured and turned into DC power by the devices connected to the network. Most people are aware of how electricity and magnetism are complementary, with corresponding fields generating one another. PoWiFi exploits this principle to generate power. Users are free to connect to the internet and go about their business as usual while the energy of their device is being replenished.

The good news: This new technology is compatible with some of the existing wireless routers, which only need a firmware update to support it.

The bad news: Federal Communications Commission (FCC) imposes a 1W maximum power output for Wi-Fi routers.
