Integration of Hybrid RF and Optical Wireless Technologies in 6G

Dear Colleagues,

The upcoming 6G networks aim to revolutionize the way we connect and communicate, with ambitious key performance indicators (KPIs) that push the boundaries of what is currently possible, attending to the forecasted increasing demands in terms of coverage, data rate, security, and energy consumption. To achieve these targets, the integration of hybrid radio frequency (RF) and optical wireless communication (OWC) technologies presents a promising solution.

Hybrid RF/OWC schemes combine the strengths of both RF and OWC technologies to address the increasing demands for ultra-high data rates, enhanced security, low energy consumption, and ubiquitous coverage in 6G networks. RF technologies, such as millimeter-wave and terahertz communications, offer high data rates and wide coverage, while OWC technologies also provide high data rates, security, energy efficiency, and robustness to EMF. The integration of these technologies can overcome the limitations of individual technologies and enable seamless communication in diverse environments, ranging from urban to rural, and from terrestrial to aerial and satellite networks.

Moreover, AI-assisted network optimization is also a key aspect of the integration of hybrid RF/OWC technologies in 6G. AI can play a crucial role in optimizing the performance of such hybrid systems, including intelligent resource allocation, network planning, interference management, beamforming, and routing. Machine learning techniques can also enhance security, privacy, and reliability in hybrid RF/OWC networks.

This Special Issue invites original research articles, reviews, and perspectives on the latest advances, challenges, and opportunities in the integration of hybrid RF and Optical Wireless Communication technologies for 6G networks.

Topics of interest include, but are not limited to,

• System architectures;
• Channel modeling;
• Waveform design;
• Modulation and coding techniques;
• Networking protocols;
• Network planning and optimization;
• AI-assisted network management;
• Deployment scenarios;
• Experimental evaluations and standardization efforts.

We aim to bring together researchers, practitioners, and industry experts to share their insights and contributions towards shaping the future of 6G networks through the integration of hybrid RF and OWC technologies, with a focus on AI-assisted network optimization.
