At CES, we were blown away by Sunpartners Wysips Connect sensor, which allows a smartphone to charge via solar power and receive data from light, using LiFi technology.Apparently, Alcatel OneTouch is equally impressed with this groundbreaking technology, because at Mobile World Congress, the company unveiled a phone with the sensor inside. We had a chance to go hands on with a prototype device at Sunpartners Mobile World Congress booth and see it grabbing power and data from an LED light. The sample we used was a version of Alcatel OneTouchs MPop phone, which contained the Wysips Connect strip as a transparent layer in its screen.
