Railway scenarios present several specific features that difficult the deployment of a radio communication
network, especially for high speed environments. Rilway passenger’s demand for high capacity communication systems
for personal purposes is continuously growing. This demand drives the installation of public commercial communication
systems: 3G, LTE, which not only coexist next to GSM-R system infrastructure, but may be also deployed in frequency
bands which lie next to GSM-R ones. This fact may lead to interference issues between both systems, as reported by several railway operators. Regarding the critical nature of railway communication systems, it is advocated the avoidance of interference issues in advance. However, this process is a complex task that must be addressed with specific software tools that takes into account the specificities of high speed railway communication systems. In this paper, the authors present a novel software tool designed for the evaluation of coexistence between high speed railway communication systems and public commercial ones.
