Abstract

Simultaneous lightwave information and power transfer (SLIPT) has been regarded as one of the enabling technologies to enhance the battery-life and data-rate for mobile electronics in the Internet of things (IoT). The existing SLIPT schemes face the challenge of achieving narrow beam transmission and mobile receiver positioning simultaneously. In this paper, we propose a simultaneous mobile information and power transfer (SMIPT) approach using the energy-concentrated resonant beam, which can realize self-alignment with the mobile receiver. To reveal the mobility mechanism of SMIPT, we present a geometric model of the mobile transmission channel and an analytical model of mobile energy and information transfer. Refraction is ignored in the geometric model and Fresnel/paraxial approximations are adopted in the above analytical model. Numerical evaluation illustrates that the exemplary SMIPT system can deliver 5 W charging power and enable 9.5 bps/Hz spectral efficiency with the moving range of 40-degree field of view (FOV) over 3 m distance. Thus, SMIPT exhibits a viable solution of simultaneous narrow beam transmission and mobile receiver positioning for high-power and high-rate SLIPT.
