WiFi is our main wireless communication source, yet it still drains battery power like no other. We’ve recently seen companies using LiFi, which uses light instead of radiowaves, in addition to projects that enable users to sell their leftover WiFi data. Jeeva Wireless, have now developed a solution that uses 10,000 times less power than traditional WiFi networking equipment. The team of student researchers have created a microchip that, instead of generating its own WiFi signal, piggybacks WiFi from another source. It makes use of a process called ‘backscattering’. WiFi is information sent through radiowaves, an energy intensive process. Energy can…
