At the Mobile World Congress 2016 in Barcelona, nok9 joined AirCharge and Rohm at the Wireless Power Consortium (WPC) booth to actively promote wireless charging technology. Visitors had the chance to learn how Qi works and observe a complete ecosystem from commercial product to chip manufacturer to test tool supplier. Visitors with Qi enabled devices could also “test” them on-site with nok9 test systems, to see how their performance compared with the latest world standards.
