Emulation of various radio access technologies for zero on site testing in the railway domain - the Emulradio4rail platforms
Résumé
In order to assess the reliability, availability, and maintainability of wireless links for the rail sector in the laboratory, it is necessary to develop measurement platforms able to emulate real railway radio environments. This type of testing platform should combine very new approaches, the so-called system in the loop (SITL) and hardware in the loop HITL). It allows connecting directly and coupling at radio frequency level (RF) the real equipment to be tested, the radio emulators (physical systems), and the simulators able to mimic the railway network and the railway channels’ behavior, including interferences. The Emulradio4rail platforms will support multiple emulation instances such as LTE, Wi-Fi, and SatCom networks. The paper will present the architecture of the platforms under development and preliminary assessments.
