ETSI's Director-General speaks of the future of railway mobile communication systems at COIT event

Sophia Antipolis, 28 June 2021

On 23 June, as part of the commemoration of the European Year of Rail, the COIT Smart Railways Working Group conducted an online session to publicise the features and advantages of the FRMCS (Future Railway Mobile Communication System). This system will replace the current GSM-R and technologically mark the next decades of a means of transport that is living its best moment.

ETSI is pleased to announce the release of the first two Group Reports developed by its Terahertz Industry Specification Group (ISG THz). They are addressing key elements in this initial phase of the pre-standardization works for THz communications: the use-cases and the spectrum. The role of ETSI ISG THz is to develop an environment where various actors from the academia, research centres, industry can share, in a consensus-driven way, their pre-standardization efforts on THz technology resulting from various collaborative research projects and global initiatives, paving the way towards future standardization. Complementing the work of other ETSI Technical Bodies and other SDOs, the group concentrates on establishing the technical foundation for the development and standardization of THz communications.

Optical fiber-based distributed communications systems that provide and support both RF communication services and digital data services are disclosed herein. The RF communication services and digital data services can be distributed over optical fiber to client devices, such as remote antenna units for example. In certain embodiments, digital data services can be distributed over optical fiber separate from optical fiber distributing RF communication services. In other embodiments, digital data services can be distributed over common optical fiber with RF communication services. For example, digital data services can be distributed over common optical fiber with RF communication services at different wavelengths through wavelength-division multiplexing (WDM) and/or at different frequencies through frequency-division multiplexing (FDM). Power distributed in the optical fiber-based distributed communications system to provide power to remote antenna units can also be accessed to provide power to digital data service components.

Intrapersonal communication systems and methods that provide an optical digital signal link between two or more local devices are disclosed. In some embodiments, the system includes a first signal converter disposed at a first end of the optical digital signal link and configured to convert between electrical digital signals from a first local device and optical digital signals from the optical digital signal link. The system can include an optical connector having a non-contact portion configured to couple optical digital signals between the first signal converter and the optical digital signal link across a gap. The system can include a second signal converter disposed at a second end of the optical digital signal link and configured to convert between electrical digital signals from the second local device and optical digital signals from the optical digital signal link.
