Soon Your Wi-Fi is not just your wireless provider of internet connection but it will also provide power to your devices as it will charge your devices to equipped it with power minus the wires. This is what researchers from the University of Washington have found out. These researches developed a system called power over Wi-Fi which recharges batteries through the air from up to 28 feet away.
The system main components includes two components that includes a router as the access point and sensors. Vamsi Talla, a researcher on the project said in connection with why there should be a custom-built sensors, is that, “The goal of the sensors is to harvest RF (radio frequency) power and convert it into DC power,” he then added that, “The second piece, the access point, there we actually developed a custom solution on it, just a software modification that would enable the access point to act both as a good power delivery source and, simultaneously, also as a good Wi-Fi router.”
Literally, it gets power over Wi-Fi and in that particular manner the two components can work well with each other without interfering individual functions. Although there’s already a certain company called Energous which have develop and already marketed a device called WattUp which according to the company is a groundbreaking technology that can relay power through the air using the RF cignal but it requires an entirely new dedicated hardware without the Wi-Fi. There is a difference with the new study of the researchers from the University of Washington since the router can become an internet and power source simultaneously. Data and Energy were provided by one single hardware device at the same time.
The researchers came up with a resolution, therefore the hardware can provide balance between charging and connectivity with this, another researcher on the project Bryce Kellogg, explains that, “If we wanted to just blast as much power as we possibly can, that would kill your Wi-Fi, because you’d have power on the channel all the time,” he goes by saying that, “We optimized the router so that we can deliver what seems like, to the sensor, constant power without impacting your Wi-Fi too much. Instead of having continuous power on one of your Wi-Fi channels, we split it among your three non-overlapping Wi-Fi channels. That allows us to deliver about the same amount of power without impacting any one channel very much.”
However, researchers still needs ample of time to nail it down exactly of where this system will work best, the time will show us all of how useful will this new system will be. In the meantime, the best we can do is just wait and see.
