T/CA 110-2020 Information technology - Inter-system remote communication and information exchange - Magnetic field networking - Part 2: In-band wireless charging control protocol

Scope

Main technical content: This document specifies an in-band network system that can simultaneously perform wireless energy transmission and data transmission within the same frequency band. The network provides technical solutions for remote and continuous power supply and stable network operation. The network design is based on the information given in ISO/IEC 15149, which enables priority control of devices while managing wireless energy transmission to requested devices. This document describes the PHY layer and MAC layer protocols and does not address issues related to upper-layer protocols. The PHY layer and media access control layer should be able to jointly perform the following tasks: data transmission, signal control, and wireless charging. This document is applicable to the following environmental scenarios: - Mobile phones: Provide a ubiquitous charging environment for portable devices; - Home appliances: Allow unrestricted placement of appliances without the need for wires or power plugs. The MAC layer protocols specified in this document are applicable to: - Variable superframe structures for wireless charging of multiple devices; - Simple and effective network topologies for efficient wireless charging; - Dynamic address allocation for efficient time-sharing among multiple devices. The PHY layer protocols specified in this document are applicable to: - A frequency band for wireless charging and magnetic field communication; - Convenient, robust modulation with low implementation cost and fault-tolerant performance; - Variable coding and bandwidth for dynamic charging environments.
