Summary

Recommendation ITU-T Y.4202 defines a framework for wireless power transmission (WPT) application service by describing concept, functional model, requirements, basic service flows and use cases. Wireless power transmission is a technology to transmit electric power wirelessly.

Applications using WPT technology are expanding to mobile and portable devices, home appliances and office equipment, and electric vehicles. In particular, WPT technology is useful in providing electric power to the Internet of things (IoT) devices in constrained environments. The WPT application service is an application service to realize various types of WPT charging for devices capable of receiving electric power wirelessly.
