Strategic DirectionTTA’s plansMarket analysis

Use

case & service scenario (4Q in 2011)

Standard

Wireless Charging protocol (1Q in 2012)

Wireless Charging interface (1Q in 2012)

Transfer efficiency

measurement

(4Q in 2012)

Collaboration

TTA plans to cooperate with other SDOs

Slide7

7

ChallengesProduct DiversificationAs market is increasing, each vendor makes the Wireless Charging system which has different structure & protocolWireless Charging is possible only between systems having the same structure & protocol

Frequency Issues

Each vendor considers different frequency bands for Wireless Charging which causes lack of interoperability between Wireless Charging systems

Regulation Issues

Each country has different regulations for EMI/EMC, EMF, etc.

Slide8

8

Next Steps / ActionsStandardization Activities for product diversificationSystem & interfaceControl & management protocolConformance test & certification

Regulation Coordination & Compromise

Frequency band

EMI/EMC

EMF

Activities toward the global harmonization

Collaboration and sharing information is needed among SDOs towards Global Standard
