GB/T 40783.2-2022 is the Chinese standard "Information technology - Telecommunications and information exchange between systems - Magnetic field area network(MFAN) - Part 2: In-band control protocol for wireless power transfer".
Its scope clause reads: This document specifies an in-band network system that can simultaneously perform wireless energy transmission and data transmission in the same frequency band.
The network and remote and continuous energy supply provide technical solutions. The design of the network is based on the principles given in ISO /IEC 15149 Magnetic Domain Networks, in this way to achieve priority in equipment control At the same time, wireless energy transmission management is performed for multiple devices in the request.
This document focuses on the PHY layer and MAC layer protocols and does not involve Matters related to upper-layer protocols. The PHY layer and the MAC layer jointly perform the following tasks. data transmission, signal control, wireless energy transmission.
This document is expected to perform well in the following use cases. ---Mobile phones. provide a ubiquitous charging environment for portable devices; ---Household appliances.
There is no need to use wires and power plugs, and electrical appliances can be arranged without restriction.
The MAC layer protocol specified in this document is expected to perform well in the following scenarios. --- Variable superframe structure for wireless energy transmission of multiple devices; ---Simple and effective network topology for efficient wireless energy transfer; ---Efficient time-sharing dynamic address allocation among multiple devices.
The PHY layer protocol specified in this document is expected to perform well in the following scenarios. --- a frequency band used for both wireless energy transfer and magnetic field communication; --- Low implementation cost and minimal error margin for convenient, robust modulation; --- Variable encoding and bandwidth for dynamic charging environments. Its clauses include terms and definitions.
