Simultaneous lightwave information and power transfer (SLIPT) has been regarded as a promising technology to deal with the ever-growing energy consumption and data-rate demands in the Internet of Things. We propose a resonant beam based SLIPT (RB-SLIPT) system, which deals with the conflict of high deliverable power and mobile receiver positioning with the existing SLIPT schemes. At first, we establish a mobile transmission channel model and depict the energy distribution in the channel. Then, we present a practical design and evaluate the energy/data transfer performance within the moving range of the RB-SLIPT. Numerical evaluation demonstrates that the RB-SLIPT can deliver more than 4W charging power and enable 3Gb/s achievable data rate with the moving range of 20° field of view (FOV) over 3m distance. Thus, RB-SLIPT can enable simultaneous high deliverable power and high data rate in mobile scenarios without tracking control.

移动性增强的同步光波信息和功率传输

同时光波信息和功率传输（SLIPT）被认为是一种很有前途的技术，可以应对物联网中不断增长的能源消耗和数据速率需求。我们提出了一种基于谐振波束的 SLIPT (RB-SLIPT) 系统，该系统解决了高可传输功率和移动接收器定位与现有 SLIPT 方案之间的冲突。首先，我们建立了一个移动传输信道模型，描述了信道中的能量分布。然后，我们提出了一个实用的设计并评估了 RB-SLIPT 移动范围内的能量/数据传输性能。数值评估表明，RB-SLIPT 可以提供超过 4W 的充电功率，并在 20° 视场 (FOV) 移动范围超过 3m 距离的情况下实现 3Gb/s 可实现的数据速率。因此，
