“…In some cases, visible light is a considerable drawback when the barrier prevents communication from progressing when no other path is accessible [ 43 , 52 , 53 ]. Furthermore, communication links can be provided while using intelligent reflecting surface (RIS) technology, digital twin technology [ 54 ], and multi-hop relaying techniques [ 55 ].…”

Visible Light Communication (VLC) has recently emerged as an alternative to RF-based wireless communications. VLC for vehicles has demonstrated its potential for Intelligent Transportation Systems (ITSs) to exchange information between vehicles and infrastructure to achieve ITS core goals, such as improving road safety, passenger comfort, and traffic flow. This paper seeks to provide a detailed survey of vehicular VLC systems. This paper presents an overview of current developments in vehicular VLC systems and their benefits and limitations for experienced researchers and newcomers.

“…By controlling and monitoring the virtual replicas in a real-time manner, it can be feasible to detect and subsequently address any maintenance issues and bottlenecks that may arise in the said industry, including device and machine complete failures, unsuccessful service delivery attempts, and material shortages, among many others. To enable the digital twinning of the manufacturing industry, THz communications/sensing systems and networks can be deployed to acquire, transmit, and receive data (and at some points enrichment information) between the physical objects and virtual replicas of the manufacturing systems, enabling real-time control, accurate decision-making, and autonomous optimization [454].…”

“…Second, in reference [456], the authors proposed a framework that is based on the THz communications system and aimed at implementing the digital-twin prediction for enabling extremely security-sensitive systems and objects. Finally, reference [454] studies the delay minimization optimization problem within the context of THz communications system and visible light communications system. In their study, the authors claim that their approach reduces up to 33.2% transmission delay in comparison with the traditional methods.…”

The sub-6 GHz spectrum and the millimeter wave frequency band, with its huge spectrum, have been exploited in the past years to meet the traffic demands of wireless communication networks. However, the limited and licensed spectrum of these bands cannot support the massive connectivity requirements, the exponential growth of data traffic, and the strict quality-of-service requirements for 6G and beyond wireless systems. Extremely high frequencies, such as optical and terahertz, which offer much wider transmission bandwidths with extreme data rate capabilities, are expected to play key roles in the 6G and beyond era. As a result, futuregeneration wireless networks will transition from single-band and heterogeneous networks to multi-band networks (MBNs), where various frequency bands coexist. Despite the great potential of MBNs, they face novel challenges from channel modeling, transceiver and antenna design, programmable simulation platforms, standardization activities, and resource allocation. This paper provides a tutorial overview from the communication design perspective of the various frequency bands, elaborating on the above issues. Then, we introduce and examine typical MBN architectures for future networks and provide a detailed overview of state-of-the-art resource allocation problems for existing MBNs that typically operate on two frequency bands. The considered resource allocation optimization problems and solution techniques are discussed comprehensively. We then identify key performance metrics and constraint sets that should be considered for resource allocation optimization in future MBNs and provide numerical results to depict how various system parameters and user behaviors can influence their performance. Finally, we present several potential research issues as future work for the design and performance optimization of MBNs.
