In Japan, ISM equipment up to a transmitted RF power limit of 50 W can use this band without permission. New rules on the specification”, which exempt permission of individual “type equipment installation application for WPT equipment, allowing transmission power greater than 50 W, came into effect in 2016. The reasons why 6 7656 795 kHz may be favoured for magnetic resonance WPT technology are summarized as follows: ISM band. – Several standardization development organizations are developing WPT standards for use – in 6 765-6 795 kHz. Small physical dimensions are possible for WPT components for example; power – transmitter coils and receiver coils. In Korea, the 13.56 MHz band is used for WPT charged 3D glasses to watch 3D TV.
