Current development of the railway industry is primarily driven by projects aimed at establishing high-speed railway lines which serve as a key catalyst for the growth of all economic sectors in light of the high levels of urbanization in developed countries. High rates of motion preclude the use of traditional wireless railway communication networks (such as the widely adopted GSM-R), necessitating the design, modeling and implementation of next-generation wireless communication systems. These communication systems must exhibit resilience against interference encountered in railway scenarios. Developing railway wireless communication networks based on radioEthernet (Wi-Fi) technology within Trackside Network (TSN) architectures is seen as the solution by many. Despite the initially limited applicability of radioEthernet technology in scenarios involving moving objects, it remains the preferred option for TSN due to its high achievable data rates [1]. This paper discusses the development and implementation of a Link-Level Simulator (LLS) for railway wireless communication networks utilizing radioEthernet 802.11ax technology.
