The key idea of energy harvesting cellular communications is introducing extra energy harvesting ability at user devices. As a practical design, a co-located or integrated receiver architecture can be employed by user devices, where the information receiver and the RF energy harvester co-exist in a time-switching or power-splitting manner.
The possibility of harvesting energy from the communicated signal itself has been discussed in the circuits literature, especially in the context of biomedical implants .
The energy harvesting technology is penetrating into many hot areas, such as the IoT, BAN, and 5G communications, providing realistic solutions for large-scale, sustainable, and low-cost environment monitoring and wireless information exchange system.
To overcome this issue, energy harvesting has emerged as a promising solution. By integrating energy harvesting receivers into power-constrained devices, the concurrent utilization of radio frequency (RF) signals for both information transmission and energy delivery can be achieved.
To develop green communications, energy harvesting from energy sources such as solar power and wind power has been studied and may have potential applications in 6G systems. While here we focus on more controllable wireless energy harvesting techniques and envision their application in cellular systems.
The RF energy is a perpetual resource that is widely present both indoors (e.g., Wi-Fi signal from wireless router) and outdoors (e.g., cellular and DTV signal).
