Advanced air mobility (AAM) is an emerging sector in aviation aiming to offer secure, efficient, and eco-friendly transportation utilizing electric vertical takeoff and landing (eVTOL) aircraft. These vehicles are designed for short-haul flights, transporting passengers and cargo between urban centers, suburbs, and remote areas. As the number of flights is expected to rise significantly in congested metropolitan areas, there is a need for a digital ecosystem to support the AAM platform. This ecosystem requires seamless integration of air traffic management systems, ground control systems, and communication networks, enabling effective communication between AAM vehicles and ground systems to ensure safe and efficient operations. Consequently, the aviation industry is seeking to develop a new aerospace framework that promotes shared aerospace practices, ensuring the safety, sustainability, and efficiency of air traffic operations. However, the lack of adequate wireless coverage in congested cities and disconnected rural communities poses challenges for large-scale AAM deployments. In the immediate recovery phase, incorporating AAM with new air-to-ground connectivity presents difficulties such as overwhelming the terrestrial network with data requests, maintaining link reliability, and managing handover occurrences. Furthermore, managing eVTOL traffic in urban areas with congested airspace necessitates high levels of connectivity to support air routing information for eVTOL vehicles. This paper introduces a novel concept addressing future flight challenges and proposes a framework for integrating operations, infrastructure, connectivity, and ecosystems in future air mobility. Specifically, it includes a performance analysis to illustrate the impact of extensive AAM vehicle mobility on ground base station network infrastructure in urban environments. This work aims to pave the way for future air mobility by introducing a new vision for backbone infrastructure that supports safe and sustainable aviation through advanced communication technology.

“…It also issued a separate opinion on these measures following the report, containing 28 measures (RSPG, 2021a). Initiatives on spectrum management are revolutionary, as wireless communications are particularly characterised by green trade-offs arising from the theoretical relationships between spectrum efficiency, energy efficiency, deployment efficiency, latency, and performance and bandwidth (Matinmikko-Blue, 2021;Csaba, 2020). Radio spectrum, on the other hand, is an essential tool for sustainable development, enabling the data connectivity behind key wireless technologies, universal broadband coverage and the resulting digital transformation.…”

Creating climate-neutral electronic communications is a shared responsibility for the industry and urgent action is needed in the face of warming trends due to global climate change. Despite this, environmental sustainability in the regulation of the electronic communications sector in Hungary has not yet received sufficient attention, nor has there been any related research, articles or studies. Therefore, the aim of this paper is to fill this gap, to review the relevant international, EU and domestic regulatory situation and trends, to provide a comprehensive and high-level picture of sustainability initiatives in the electronic communications sector and to evaluate it in order to suggest possible directions for domestic regulatory action. It is hoped that this will serve as a starting point for launching a discourse in the industry and for properly positioning the green transition in electronic communications regulation.

Fronthaul data rates in case of mmWave wireless systems scale up to several Gbps in the currently deployed digitized radio over fiber solutions, resulting in large complexity remote radio heads (RRHs). We propose a promising solution involving optical frequency doubling and quadrupling, where all complex digital processing are moved to the centralized base band unit (BBU), thereby allowing placement of large number of low-complex RRHs at long distances. We experimentally demonstrate optical frequency doubling and quadrupling for the generation and transport of millimeter wave (mmWave) signals with OFDM containing QPSK, 16/64/256-QAM modulation formats over a distance of 2 km. These schemes enable the use of low-frequency RF signals at the BBU for the generation of mmWaves at the remote radio head (RRH). We evaluate the performance of the systems in terms of error vector magnitude (EVM) and out-of-band emissions of the upconverted data. Our results show that the proposed schemes achieve EVM values within the 3GPP 5G standard requirements. We also investigate the tunability and scalability of the proposed schemes across the n258 band (24.25 -27.5 GHz) and discuss the feasibility of implementing dense wavelength division multiplexing (DWDM) for servicing multi-channel operation required for multisector antennas. The proposed schemes can support high data rate transmission for future wireless networks including 6G.INDEX TERMS Analog radio over fiber, fronthaul, frequency doubling, frequency quadrupling, optical upconversion, mmWave 5g, mmWave generation, EVM.
