Can Wi-Fi signal charge our gadget?
Researcher are developing ways on how the Wi-Fi signals can be use to charge devices.
Many people regard Wi-Fi as the King, since the development of Wi-Fi in the technology world, it has change possible things that we can do with our gadget. Wi-if has been around about 15 years now, though it still in its infant stage, the wireless networking standard has developed rapidly over the years.
A group from the University of Washington is developing this technology to allow us charge or boost our batteries without attaching any plug to our devices. they called it "PoWi-Fi" or "Power over Wi-Fi"
The tech uses two access point: a router and a custom sensors. The sensors uses radio frequencies and change them to direct current power. By splitting your Wi-Fi channel on the router into three rather than one, the group can ensure strong power delivery without disrupting the connection.
So in layman's terms, you may soon be able to charge your gadget from up to 28 feet away without slowing down the signal you're receiving while you scroll through your Instagram feed.
So will it be safe to ditch that charger once and for all? Not yet.
The team has installed the technology in six Seattle-area homes. During the trial phase, one household found the added technology sped up connectivity, while another had trouble viewing a YouTube video. But overall, the test was a success.
The team has also tested it with cameras and rechargeable batteries. They've founded a startup to help turn their research into an actual product. But for now, there's no time frame for when we might see the technology in our own homes, corner cafes or workplaces.
