GSC17-PLEN-23r2 Standards for Shared ICT GSC-17, Jeju / Korea 2 Highlight of Current Activities(1/2) TTA Wireless Power Transmission/Transfer (WPT) PGs developed 10 domestic Standards/Reports such as WPT use case & service scenario, definition of efficiency, evaluation method, in-band resonant WPT system and management for WPT Followings are work areas within TTA - WPT applications and services of ICT appliances' equipment standardization - WPT of IT appliances' vehicles and mobile device standardization - WPT technologies and measurements standardization to operate chips or cells - Affects on human body Source : ISO 17465

GSC17-PLEN-23r2 Standards for Shared ICT GSC-17, Jeju / Korea 3 Highlight of Current Activities(2/2) Source : ISO TTA PGs actively participate in related international standardization activities such as APT AWG, CJK and GSC for the collaboration and interoperability on WPT Particularly, in this year TTA PGs will review De-facto Technical specifications from WPC, A4WP, etc. for adoption as TTA Standards. Also, TTA PGs will review the TTA Standard on ‘Management Interface for WPT Multi-devices (TTAC.KO ) (see Supplementary Slides)’ accommodating multiple power source from different technologies method for example resonance and inductive WPT.

GSC17-PLEN-23r2 Standards for Shared ICT GSC-17, Jeju / Korea Strategic Direction Interoperability among the WPT products in same application should be achieved by standardization effort to the maximum extent possible. Sharing related information and collaborating among GSC members are important to encourage technology development as well as global harmonization. GSC needs to offer opportunities to its members to discuss related issues including standard deveopment activities

GSC17-PLEN-23r2 Standards for Shared ICT GSC-17, Jeju / Korea 5 Challenges Product Diversification - As market is increasing, each Alliances make the WPT Technical Specifications which has different structure & protocol Frequency/Regulation Issues - International standards and harmonized radio frequency, EMI/EMC, and SAR (Specific Absorption Rate) regulations are necessary for its effective global solution deployment - It is reported that magnetic resonant WPT products for portable device and CE devices using lower WPT power are expected to come out in the market in 2014 in some countries, which may utilize the current radio regulations intended for the existing products. - For WPT for Electronic Vehicle and high-power applications, the earliest deployment is expected in 2015 as new regulatory discussions are necessary to introduce

GSC17-PLEN-23r2 Standards for Shared ICT GSC-17, Jeju / Korea 6 Next Steps / Actions Sharing information in the CJK and other SDOs is important to achieve regional and global harmonization in WPT technology standardization and regulation. It is time to prepare further development of global harmonization in technology and regulation to achieve maximum interoperability. It is proposed to set up Task Force (TF) for developing GSC Report on WPT based on CJK WPT TR 1 including other SDO’s information and further global direction before GSC-18.

GSC17-PLEN-23r2 Standards for Shared ICT GSC-17, Jeju / Korea 7 Proposed Resolution It is proposed to modify Resolution GSC-16/34 taking into account current status that have occurred in the WPT standardization area - to change the title of WCS into WPT considering ITU and ISO’s terms - to work together through GSC TF and report to GSC-18 Attachment: Proposed Modification of Res. GSC-16/34
