“…The target signal level is at 15 dBm (minimum, suitable for Mode 2 operation) and 25 dBm (suitable for Mode 3 operation) for a reliable signal. For a variable mmWave-Li-Fi 5G transceiver, the active semiconductor devices process technologies and subsystem design topology determine the receiver sensitivity [22][23][24][25][26][27][28].…”

Despite modern vehicles having the necessary advanced driver assistance systems (ADAS) for autonomous operation, current implementations rely solely on sensor information from the surrounding environment or data from smart infrastructure. However, shortcomings in current implementations and standards around cost-effective variable latency and data rate have prevented widespread adoption of the technology to enable autonomous operation. This paper presents a proof-of-concept (PoC) reconfigurable design and performance of a hybrid high-ultra-high bands [i.e., millimetre-Wave (mmWave)-light fidelity (Li-Fi)] fifth generation (5G) architecture for autonomous vehicular communication applications. The hybrid multiple input multiple output (MIMO) system architecture design is mathematically modelled and presented. The reported prelim PoC validation focuses on the Li-Fi experiment and results. The proposed hybrid system's effectiveness was evaluated using the open-source "Model-based Autonomous Traffic Simulation" (MOBATSim). The simulation results of a potential Li-Fi system and a PoC prototype are presented to demonstrate the role of the Li-Fi system in the proposed hybrid mmWave-Li-Fi 5G architecture. Three models of LED/lamp and two models of photodiode were simulated at three different vehicle speeds to ascertain the potential of the system. Promising results are reported at low speeds with received power values of up to -8.39 dBm and signal to noise ratios of up to 29.39 dB. Practical prototype simulations showed auspicious results including received power of -24.6 dBm to -34.12 dBm at the vehicle speeds of 10 MPH to 30 MPH respectively. The implemented PoC Li-Fi technology component has demonstrated the ability to transmit information with a theoretical output of 333 bits per second at 1.92 m, without the use of any highpower processors, components, and modulation techniques. The proposed system yields high data rates due to reconfigurable high bandwidth channels; many simultaneous multimedia mmWave-Li-Fi connections enabled due to spatial reuse with narrow beams; and easier mmWave-Li-Fi ultra-low latency support occasioned by smaller packet sizes. This holds a great promise for the hybrid 5G/6G mmWave-Li-Fi autonomous vehicular communication use case and/or applications.

“…One of the V2V communication system methods is using a VANET (Vehicular Ad hoc-Network). VANET has characteristics in the pattern of data transmission, namely by forming the path from the sender to the most remote recipient by utilizing the vehicle around it as a node to determine the shipping path [10]. Another method is using Visible Light Communication (VLC), a communication system using Light Emitting Diode (LED) lights as transmission media.…”

Based on data from the Indonesian Traffic Corps by September 2019, the number of car accidents was dominated by rear-hit crashes with 6,966 accidents. Most of these accidents occurred during car convoys. It needs a car-to-car communication to increase driver awareness. One of the technologies that can be applied is Visible Light Communication (VLC) and infrared communication. The transmitted data are the vehicle speed data, throttle position, and brake stepping indicator. The data are obtained by reading the Engine Control Unit (ECU) in the car. The data are packaged from the three data and sent to other cars at day and night using VLC and infrared communication. The experimental results show that in a communication system that uses VLC, data can be exchanged between cars during the day up to 2 meters and at night up to 11 meters. Otherwise, in infrared communication, vehicles can communicate during the day up to 2 meters and at night up to 0.7 meter. The test was also carried out with some conditions such as rain, smoke, passers, and other vehicle lights.

“…Various aspects of the Li-Fi technology have developed rapidly over the past decade: various modulation schemes have been investigated [13], new emitters have been developed [14], and the integration of Li-Fi into existing networks has been studied [15]. To provide the vehicle communication via Li-Fi, a number of works suggest using lighting equipment on the front and back of vehicles, as well as integrating it into traffic lights [16][17][18][19][20]. In these studies, the main focus is on electrical circuits and on common circuits for constructing communication networks.…”

One of the features of an intelligent transport system is the formation of communication channels between vehicles. Vehicle-to-vehicle communication will help reduce the number of road accidents. Li-Fi technology is considered as a method for communication. Li-Fi uses visible light for data transmission. A single source of radiation may not be sufficient to provide a certain signal level at the receiver, so multiple sources must be used. Also, signal transmission should be in all directions in the horizontal plane. The study addresses the problem of designing optical systems of circular radiation with several multidirectional sources. It proposes the modification of the ray mapping method for the task of designing optical elements for the Li-Fi wireless communication technology between vehicles. Also, it describes the algorithm for calculating optical systems of circular radiation for a signal source and signal receiver. Finally, the results of calculating and virtual prototyping of devices designed by the proposed method.
