A University of Washington team is presently undergoing a new and interesting research through which the so called “power over Wi-Fi” system is being developed.
The above mentioned system will most probably be able to recharge your gadgets’ batteries wirelessly, through the air, so no more wires or plugs shall be needed. It will do so from up to 30 feet away.
The Wi-Fi network which is currently being used only to connect devices to the internet, will soon be able to do two things at once, so to speak. It will charge devices’ batteries as well as connect them to the Internet thanks to the efforts of the masterminds of University of Washington.
Vamsi Talla, who takes part in the project argued that part of the already existing Wi-Fi infrastructure could be better usedby redistributing and re-purposing it to wirelessly power charge devices in offices and homes.
“Power over Wi-Fi” contains two components, a router and custom-built sensors which could harvest radio frequency then convert it into DC power.
As far as the router is concerned, Vamsi Talla explains that his team has already tried its hands at implementing
a custom solution on it, meaning that through a software adjustment, the access point will be able to act as a system of power delivery as well as a functional Wi-Fi router.
The team has done a good job extending the distance to up to 30 feet, so the router could be strong enough to charge a device even through a brick wall.
However, there are also a few drawbacks concerning the project.The most frequently raised question is whether a single router could output sufficient power to be able to both charge and provide connectivity uninterruptedly.
The research members are confident however, and let out that through their router optimization, they will be able to split the power between the three non-overlapping Wi-Fi channels instead of using a single Wi-Fi channel continuously. They have put their words to practice and and tested the system’s capability in six homes from Seattle.
Five of the six homes’ owners have given positive feedback, declaring that while the router was charging their gadgets they did not experience any sort of difficulty surfing on the Internet at the same time.
The research is at its dawn for the time being, yet they are examining the marketing possibilities and are also on a constant outlook for any technological updates and improvements.
