Document Type and Number:
WIPO Patent Application WO/2012/091211
Kind Code:
A1
Abstract:
The present invention relates to a method of charging a multi node wireless charging system using magnetic field communication, which effectively charges a plurality of nodes through magnetic field communication, prepares a magnetic field communication protocol for wireless charging, and selects an appropriate wireless charging device accordingly for charging during an appropriate time. The wireless charging method of the present invention includes: transmitting an association request frame, receiving an association response frame from the wireless charging device, transmitting a charging requirement request frame, receiving a charging requirement response frame from the wireless charging device, transmitting a charging preparation request frame, and transmitting power during a receiving section of a charge requirement response frame for the charging preparation request frame.
