“…In this perspective, how the access networks, metro, core networks, high-performance cloud data center networks (DCNs), as well as the associated edge services and Internet of Things (IoT) devices are designed and deployed will be affected [1][2][3]. Furthermore, the emergence of IoT devices has brought about the unprecedented expansion of Internet connections [4,5]. Their proliferation and effective support for several innovative applications and services such as cloud computing, augmented reality (AR), massive machine-to-machine communication, and emerging web applications have considerably contributed to the growing increase in machine-and usergenerated data traffic.…”

This paper reviews recent progress on different high-speed optical short- and medium-reach transmission systems. Furthermore, a comprehensive tutorial on high-performance, low-cost, and advanced optical transceiver (TRx) paradigms is presented. In this context, recent advances in high-performance digital signal processing algorithms and innovative optoelectronic components are extensively discussed. Moreover, based on the growing increase in the dynamic environment and the heterogeneous nature of different applications and services to be supported by the systems, we discuss the reconfigurable and sliceable TRxs that can be employed. The associated technical challenges of various system algorithms are reviewed, and we proffer viable solutions to address them.

“…Um dos principais desafios das redes 5G atuais é o alto consumo de energia das redes de acesso de rádio (RANsradio access networks) [4]. Aproximadamente 30% do custo total da rede está relacionado aos gastos com energia, sendo que somente a estação rádio base consome em média cerca de 60% da potência total disponível nos sistemas celulares [5].…”

“…Nessa arquitetura, o processamento do sinal é concentrado na central de operações (CO), reduzindo o consumo de potência das RAUs. Consequentemente, a densificação de small cells se torna viável, uma vez que a CO é conectada a várias RAUs por meio de enlaces de fronthaul baseados em fibra óptica [4,8]. No entanto, à medida que o número de small cells implantadas aumenta, a distribuição de energia se torna um desafio nas redes 6G.…”

Resumo-Este trabalho relata a implementação experimental de um sistema radio-over-fiber (RoF) bidirecional baseado na transmissão óptica de energia e dados por meio da técnica powerover-fiber (PoF). No sistema proposto, um módulo RoF utilizado para transmissão/recepção bidirecional de sinais é alimentado utilizando PoF. O desempenho do sistema PoF foi avaliado em termos de eficiência e estabilidade de potência, enquanto que medições de EVM RMS demonstraram o funcionamento do sistema RoF. Aproximadamente 2,7 W de potência elétrica foram obtidos para alimentar o sistema RoF, resultando em taxas de transmissão de até 3,2 Gbps para downlink e 1 Gbps para uplink.

The evolution in the Information and Communications Technologies industry results in excessive energy consumption and carbon dioxide emission in the wireless networks. In this context, energy efficiency in mobile networks has been attracting considerable attention as green communications and operational expenditures reduction depend on it. Although the Internet of Things is to be supported by devices that are low-energy consuming, the power consumption of the huge number to be connected for several applications and services demand significant attention. To offer insights into green communications, this paper reviews various energy efficiency improvement techniques. Also, we consider a hybrid model in which the main grid power and dynamically harvested green energy from renewable energy sources can be leveraged to support the energy demand of the radio access network. In this regard, we reformulate the energy consumption model and consider an energy-efficient power allocation algorithm for green energy optimization. Numerical results show that with resource allocation algorithm exploitation, the energy efficiency can be enhanced. Besides, the amount of the grid energy consumption can be considerably minimized, resulting in the greenhouse gas emissions reduction in the wireless networks. Keywords 5G • 6G • cloud RAN • dense networks • energy efficiency • energy harvesting • green communications • green energy • power consumption • wireless network.
