Smart cities like Neom require efficient and reliable transportation systems to support their vision of sustainable and interconnected urban environments. High-speed trains (HSTs) play a crucial role in connecting different areas of the city and facilitating seamless mobility. However, to ensure uninterrupted communication along the rail lines, advanced communication systems are essential to expand the coverage range of each base station (BS) while reducing the handover frequency. This paper presents the dual transceiver free space optical (FSO) communication system as a solution to achieve these objectives in the operational environment of HSTs in Neom city. Our channel model incorporates log-normal (LN) and gamma–gamma (GG) distributions to represent channel impairments and atmospheric turbulence in the city. Furthermore, we integrated the siding loop model, providing valuable insights into the system in real-world scenarios. To assess the system’s performance, we formulated the received signal-to-noise ratio (SNR) of the network under assumed fading conditions. Additionally, we analyzed the system’s bit error rate (BER) analytically and through Monte Carlo simulation. A comparative analysis with reconfigurable intelligent surfaces (RIS) and relay-assisted FSO communications shows the superior coverage area and efficiency of the dual transceiver model. A significant reduction of up to 76% and 99% in the number of required BSs compared to RIS and relay, respectively, is observed. This reduction leads to fewer handovers and lower capital expenditure (CAPEX) costs.

“…Due to the harsh optical signal propagation condition, the actual performance of FSOC is significantly affected by the outdoor optical channel characteristics in distinct application scenarios. Up to know, most works are limited to the investigation of outdoor long range, even ultra-long range FSOC channel characterization and performance optimization, which to a large extent ignore the research and exploration of middle-or short-range FSOC, especially the promising Internet of Things (IoT) scenarios [6][7][8][9][10].…”

In upcoming 6G era, free space optical wireless communications (FSOC) are viewed as promising enabling techniques for backhaul and access of next-generation wireless networks. Channel modeling and characterization is the essential composition to predict FSOC system performance and feature, especially for outdoor application. Objectively, light emitting diodes (LED) are the popular and cost-efficient optical sources for short- and middle-range outdoor FSOC links. Up to know, the concerned LED beams are assumed to follow the well-known Lambertian radiation patterns for outdoor FSOC domain, which actually ignore the diversity and effect of the non-Lambertian radiation patterns of the commercially customized LEDs. For addressing the above issue, typical LUXEON Rebel non-Lambertian optical beam is adopted to configure the distinct LED beams-based outdoor FSOC links. Numerical results illustrate that more dispersive horizontal coverage characteristic could be derived from the LUXEON Rebel non-Lambertian FSOC links.
