  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 (IoT). We propose a
resonant beam based SLIPT system (RB-SLIPT), 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 5 W
charging power and enable 1.5 Gbit/s achievable data rate with the moving range
of 20-degree field of view (FOV) over 3 m distance. Thus, RB-SLIPT can
simultaneously provide high-power energy and high-rate data transfer, and
mobile receiver positioning capability.
