Title:
IN-BAND COMMUNICATION FOR WIRELESS POWER TRANSFER
Document Type and Number:
WIPO Patent Application WO/2014/027710
Kind Code:
A1
Abstract:
This item defines the physical layer and the media access control layer protocols of in-band communication for a wireless power transfer system with multiple devices charging; particularly on MFAN that shares the same frequency band for both wireless power transfer and magnetic field communication. Consumers prefer this simplified improvement in a system which supplies power wirelessly to multiple devices at the same time. In order to efficiently control and manage the multiple devices charging, a magnetic field communication link provided by MFAN should be supported for a wireless power transfer system. This item defines the physical layer and the media access control layer protocol by which a magnetic field communication link provided by iWPTN is created, and data, control signals, and wireless power are exchanged between a basestation and devices.
