Experimental mmWave channel sounding in the 60 GHz band in railway environments
Résumé
Railways are facing an ever increasing needs for safe and secure wireless communications with the generalisation of automatic and driverless trains. In this context, frequency scarcity is a real bottleneck. To overcome this blockage, opportunities offered by mmW frequency bands are explored. Due to the specificity of environments, researches conducted for general 5G and beyond deployments can not be transposed easily. Channel sounding in the mmW bands in real railways environments should be conducted. In this context, this paper presents preliminary experimental results in a railway environment with a relative low cost and reconfigurable channel sounder operating at 60 GHz.
