Finally, only 20% of the participants indicated that their products are compliant with railway norm
EN-50155 (see Figure 52), lower even than those who could not provide an answer. When asked to
provide more details about the railway norms their products complied with, most SATCOM
respondents showed little or no specific conformance to such norms.

Despite a low degree of conformance to railway-specific norms (see Section §7.2.2.2), most SATCOM
providers report a high qualitative assessment on the suitability of their products for the railway
domain (see Figure 53).
