Anything to save smartphone power is a bonus and of course it is been worked on by all manufacturers worldwide,at that we have power saving options on our devices and settings to adjust but it does not cut it for many power user’s especially ,also on top of this we now see batteries getting bigger but often the case it proves pointless due to the phones internal spec and screen’s which again is getting more powerful year by year,after this we have the option of portable chargers and so on…
Popular Science reports – A researcher at NASA’s Jet Propulsion Lab, Adrian Tang, working with UCLA professor M.C. Frank Chang, has developed a Wi-Fi chip for use in mobile electronics that uses 100 times less power than traditional receivers. This could extend battery life in nearly every device that uses Wi-Fi, and Tang is trying to focus on the expanding market for wearables.
To do something on the internet (like view this website), your smartphone generates and sends a signal out to your router, and your router generates and sends a new signal back to it. Tang’s Wi-Fi chip reflects a constant signal sent by a specialized router, instead of generating its own original signal. Data is imprinted on the signal when it’s reflected, so all the heavy lifting is essentially done on the router’s side.
“Because you’re only imprinting on a Wi-Fi signal, you’re not generating it, you don’t need power,” Tang said.
The researchers claim to have reached speeds of 330 megabits per second when transferring files with this technique, which outpaces a majority of consumer Wi-Fi routers. (In more real-world terms, 330 megabits per second is just over 40 MB/s.) They did this test with a mock wearable, built in their lab
“When you send a signal to the room, the whole room reflects back to you,” Tang said. “So you need to figure out what’s coming from the wearable and what’s coming from the background and get rid of the background.”
NASA and UCLA have joint ownership of the idea and are in talks with a commercial partner to bring the technology to market, but they also see this technology being used to conserve energy in space.
This all sounds pretty cool and if NASA is involved it surely will be….
