In this paper, the application of simultaneous lightwave information and power transfer (SLIPT) for the fronthaul link of an aerial base station (ABS) is studied. SLIPT is a particularly attractive solution for such links, since the directive free-space optical link can provide ultra-high throughput as a fronthaul, while simultaneously transferring considerable amounts of energy to extend the flight duration of the ABS. In general, large receiver areas can be utilized by a SLIPT system to enhance both its data rate and the harvested power, as they balance out the geometric spreading of the beam. However, a larger solar cell area naturally leads to a heavier load for the ABS increasing its power consumption and, in turn, lowering its expected lifetime. Therefore, it is crucial to study the ensuing trade-off between the size of the solar cell and the performance of the ABS. Moreover, SLIPT performance is heavily influenced by the …
