The use of orthogonal frequency-division multiplexing with adaptive bit and power loading results in a peak data rate of 1041 Mb/s at a bit-error ratio (BER) of 2.2×10−3 under short-circuit conditions. The receiver is shown to provide power harvesting with an efficiency of 41.7% under the irradiance of 0.3 W/cm 2 and simultaneous data communication with a rate of 784 Mb/s at a BER of 2.8×10−3 . The experimental system is envisioned to become a paradigm for next-generation wireless backhaul communications and Internet-of-Things applications.enPhotovoltaik5G mobile communicationenergy harvestinggallium arsenideInternet of ThingsOFDMphotovoltaic cellsimultaneous lightwave information and power transfervertical-cavity surface-emitting lasersIII-V- und Konzentrator-Photovoltaik621535697journal article
