“…Moreover, ordinary solar panels can turn sunlight into energy and at the same time act as data detectors for high-speed optical wireless signals [285]. A last-mile proof-of-demonstrator of an ordinary solar panel acting as an optical wireless data receiver and energy harvesting device has been deployed at the Orkney island in Scotland/UK [300].…”

The fifth generation (5G) wireless communication networks are being deployed worldwide from 2020 and more capabilities are in the process of being standardized, such as mass connectivity, ultra-reliability, and guaranteed low latency. However, 5G will not meet all requirements of the future in 2030 and beyond, and sixth generation (6G) wireless communication networks are expected to provide global coverage, enhanced spectral/energy/cost efficiency, better intelligence level and security, etc. To meet these requirements, 6G networks will rely on new enabling technologies, i.e., air interface and transmission technologies and novel network architecture, such as waveform design, multiple access, channel coding schemes, multi-antenna technologies, network slicing, cell-free architecture, and cloud/fog/edge computing. Our vision on 6G is that it will have four new paradigm shifts. First, to satisfy the requirement of global coverage, 6G will not be limited to terrestrial communication networks, which will need to be complemented with non-terrestrial networks such as satellite and unmanned aerial vehicle (UAV) communication networks, thus achieving a space-air-ground-sea integrated communication network. Second, all spectra will be fully explored to further increase data rates and connection density, including the sub-6 GHz, millimeter wave (mmWave), terahertz (THz), and optical frequency bands. Third, facing the big datasets generated by the use of extremely heterogeneous networks, diverse communication scenarios, large numbers of antennas, wide bandwidths, and new service requirements, 6G networks will enable a new range of smart applications with the aid of artificial intelligence (AI) and big data technologies. Fourth, network security will have to be strengthened when developing 6G networks. This article provides a comprehensive survey of recent advances and future trends in these four aspects. Clearly, 6G with additional technical requirements beyond those of 5G will enable faster and further communications to the extent that the boundary between physical and cyber worlds disappears.

“…In OWC, the photodetector converts the propagated optical signal into an electrical signal. The works in [178]- [181] proposed an OWC receiver using a solar panel as a photodetector so that it can convert the optical signal into an electrical signal without any external power and even generate extra energy. Thus, OWC offers great potential for realizing 6G, especially when it is powered by solar energy, considering the high data rate and SSNs of 6G.…”

<div> <div> <div> <p>Renewable energy (RE)-powered base stations (BSs) have been considered as an attractive solution to address the exponential increasing energy demand in cellular networks while decreasing carbon dioxide (CO2) emissions. For the regions where reliable power grids are insufficient and infeasible to deploy, such as aerial platforms and harsh environments, RE has been an alternative power source for BSs. In this survey paper, we provide an overview of RE-enabled cellular networks, detailing their analysis, classification, and related works. First, we introduce the key components of RE-powered BSs along with their frequently adopted models. Second, we analyze the proposed strategies and design issues for RE-powered BSs that can be incorporated into cellular networks and categorize them into several groups to provide a good grasp. Third, we introduce feasibility studies on RE-powered BSs based on the recent literature. Fourth, we investigate RE-powered network components other than terrestrial BSs to address potential issues regarding RE-enabled networks. Finally, we suggest future research directions and conclusions. </p><p><br></p> </div> </div> </div>

“…Based on the previous discussion, our proposed solution procedure for (P1) proceeds as shown in Algorithm I. At first, a set of initial solutions F is created using the feasibility problem (P4) solution along with two equal allocation vectors, that will be discussed later (they are added to F if they satisfy the energy harvesting requirement) as indicated in lines (2)(3)(4)(5)(6)(7)(8). Afterwards, (P1)…”

“…In addition, such systems can be very beneficial in providing indoor localization services with a great accuracy [4]. Furthermore, energy can be harvested from light and used to support limited energy devices [7], [8]. Energy consumption at the user equipment has become a very important aspect in new wireless communications networks especially with the evolution of Internet-of-things paradigm [9].…”
