In addition, there is a global tendency to compete against the Qi standard by promoting other specifications and standards. Regarding the electromagnetic induction and magnetic resonance methods, the R6.3 subcommittee of the Consumer Electronics Association (CEA) of the US formed a working group to develop standards. And the WG4 group that develops standards for magnetic resonance is headed by technicians from Qualcomm Inc. The Telecommunications Technology Association of Korea (TTA) plans to take over the existing WPT specifications of the Consumer Electronic Association (CEA). In Germany, the Consumer Electronics for Automotive facilitates the standardization of the interface between automotive electronic control units (ECU) and portable terminals. Consumer Electronics for Automotive facilitates (CE4A, a group established by Audi, GMW, Daimler and Volkswagen in 2006, was later joined by Mercedes-Benz, Porsche, Peugeot and Citroen, and Ford. Also Participating is the Japan Automotive Software Platform and Architecture (JASPAR) through cooperation, which exchanges information with the Automotive Application Group (AAG) of the WPC.)
