It reflects a constant signal sent by a customised router instead of generating its own original signal.

The JPL/UCLA Wi-Fi reflector chip.
A NASA researcher has developed a Wi-Fi chip for wi-fi telephones, computer systems and wearable units that makes use of one hundred occasions much less energy than conventional receivers.
Adrian Tang, researcher at NASA’s Jet Propulsion Lab in California and University of California-Los Angeles developed this new Wi fi and the best part of this device is that it can extend the battery life of every device that uses Wi Fi. This needs to be represented somehow in the system the wearable device uses to communicate, as per a PTI report. The router does almost all the work, allowing the chip to run on a very small amount of energy.
The USP of this chip is that it does not need power as the WiFi signal is not being generating, but instead it is just being imprinted on the signal when it is reflected.
The researchers stated that by reducing the power necessary to transmit and receive information through a wearable device to a computer, cellular or Wi-Fi network, users can use their the technology they are wearing to the maximum extent.
The research team claims to have reached speeds of 330 megabits per second when transferring files with this chip. And to solve this issue, Tang and Chang created a wireless silicon chip which senses and suppresses background reflections by enabling the Wi-Fi signal to be transmitted without interference from surrounding objects. It’s also the sort of technology that could find a home in space vehicles.

NASA and UCLA are now in talks with a partner looking to bring this technology to the commercial market, which means we may soon be saving a good deal of battery power in our mobile devices.
