近几十年来，微波功率传输（MPT）技术的进步使远距离无线功率传输成为可能。无线通信的最新突破——大规模MIMO、小蜂窝和毫米波通信——使无线网络成为实现MPT的合适平台。这可以消除将移动设备连接到电网进行充电的“最后一根电线”，从而解决长期存在的巨大ICT挑战。此外，MPT与无线通信的无缝集成开辟了无线供电通信（WPC）的新领域，并产生了许多新的研究方向，如信息和功率的同步传输、WPC网络体系结构以及安全高效的WPC技术。本文通过描述WPC的主要特性、揭示一系列常见问题、确定关键设计问题并讨论可能的解决方案，对WPC进行了介绍。
The advancements in microwave power transfer (MPT) over recent decades have enabled wireless power transfer over long distances. The latest breakthroughs in wireless communication - massive MIMO, small cells, and millimeter-wave communication - make wireless networks suitable platforms for implementing MPT. This can lead to the elimination of the "last wires" connecting mobile devices to the grid for recharging, thereby tackling a huge long-standing ICT challenge. Furthermore, the seamless integration between MPT and wireless communication opens up a new area called wirelessly powered communications (WPC) where many new research directions arise, such as simultaneous information and power transfer, WPC network architectures, and techniques for safe and efficient WPC. This article provides an introduction to WPC by describing the key features of WPC, shedding light on a set of frequently asked questions, and identifying the key design issues and discussing possible solutions.
