This scenario is incentivising cellular and LEO Satcom operators to work together more intelligently, reliably, and securely.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>LEO Satcom<\/strong> \u2013 combined with <strong>cellular networks<\/strong> &#8211; represent a cost-effective solution to bridge coverage gaps and improve resiliency, reducing reliance on ground infrastructures whereas telecom traffic is not sufficient to justify dedicated networks.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Proprietary satellite terminals, with limited interoperability, that instead is a fundamental requirement for the standard ERTMS system, are no more necessary. In fact, LEO Satcom have recently embraced the <strong>3GPP<\/strong> standards for <strong>D2D direct-to-device<\/strong> communications, in which satellites communicate directly with standard user equipments.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">These telecom frontiers open to new solutions for the future of railway communications, including the <strong>FRMCS,<\/strong> as demonstrated by <strong>S5LECT<\/strong> project, funded by <strong>EUSPA<\/strong> and led by SNCF R\u00e9seau in a consortium with Hitachi Rail, Radiolabs and other partners. LEO satcom in conjunction with public mobile networks allow to reduce investments, lead time, civil works impacting on train circulation, energy &#8211; lowering CO2 emissions &#8211; thus contributing &nbsp;for deploying and operating the new standard <strong>5G-based FRMCS<\/strong> network, the successor of the obsolete GSM-R network.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">At the final event of the S5LECT project &#8211; held October 8<sup>th<\/sup>, 2026, at Hitachi Rail in V\u00e9lizy &#8211; project&#8217;s main results were shown, including field trials and laboratory simulations performed by the <strong><em>end-to-end<\/em> LEO satcom emulator<\/strong> developed by Radiolabs in collaboration with its associated laboratory at University of Roma Tor Vergata.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The results have clearly confirmed the suitability of LEO satcom \u2013 already operational &#8211; and with further constellations to become operational &#8211; including the European <strong>IRIS\u00b2<\/strong> &#8211; a new telecom ecosystem will be available for the FRMCS. That scenario was anticipated by Radiolabs in 2015 when &#8211; first in Europe &#8211; had developed and validated a multi-bearer satcom and cellular platform on the railways lines in Sardinia with Ansaldo STS (now Hitachi Rail STS) and RFI &#8211; &nbsp;laying the groundwork for the use of public networks in anticipation of GSM-R obsolescence.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Since \u201cthe journey continues\u201d as stated at the S5LECT event in Velizy, Radiolabs is now focusing its research on <strong>AI techniques<\/strong>, to gathering a comprehensive data set of LEO satcom performance in operational scenarios. These data \u2013 once categorised &#8211; will be the basis for the training <strong>AI-driven trusted multi-bearer<\/strong> networks using non-trusted public networks.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Radiolabs is also involved on developments of <strong>hi-fidelity simulation and validation<\/strong> tools to assess the performance of multi-bearer platforms without relying on extensive and not exhaustive tests on field. LEO Satcom and 5G represent a viable alternative also for the wireless networks as an alternative to the cables for connecting central posts with the numerous wayside object controllers along the railways lines.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/s5lect-project.eu\/\" target=\"_blank\" rel=\"noreferrer noopener\">https:\/\/s5lect-project.eu\/<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Concluding S5LECT project new opportunities arise After years of 5G operative services, new LEO Satcom constellations have emerged &#8211; backed by billionaire investments &#8211; to expanding coverage and capacity of terrestrial networks.
