A unique chip developed by NASA will significantly increase the operating time of mobile devices using Wi-Fi communication technology. NASA's Jet Propulsion Laboratory researcher Adrian Tan and UCLA professor Frank Chang have developed a Wi-Fi chip that consumes a hundred times less power than existing models.
Receiving any information from the Internet (for example, by downloading this site), the mobile device generates and sends a signal to the Wi-Fi router. That, in turn, generates a response signal and sends it back.
The new chip from NASA scientists works a little differently: instead of generating its own signal, it reflects the constant signal of the router, superimposing useful information on it. Thanks to this, the power of the power supply built into the smartphone is practically not consumed, because all the "hard" work is done on the side of the router.
Scientists claim that they obtained a data exchange rate of 40 Mb / s, while the main technical difficulty was in separating the information of the mobile device from the re-reflected signals. Negotiations are currently underway with investors to bring the development to the market.
