Systems for people on the move

Bringing the power of ICT to a world of mobility

Information and Communication Technologies (ICT) are revolutionizing the transport sector, increasing efficiency, reliability and safety and reducing energy consumption. We support:

  • road
  • railways
  • aviation
  • maritime transportation

with activities which are carried out by key industry players and therefore reflect true market demand.

Standardization for road transport is focused on wireless communications for Cooperative ITS, with a priority on safety.

For Railway Telecommunications, ETSI deals with interference issues with public systems and standards on the interoperability of the European rail system.

ETSI works with other organizations to develop standards and Community Specifications (CSs) for Air Traffic Management (ATM) equipment. ETSI supports the Single European Sky (SES) initiative with the development of "Community Specifications" in response to European commission mandates.

ETSI produces European Standards for communications equipment falling within the scope of the Marine Equipment Directive and the River Information Services Directive. We also produce European Harmonized Standards for communications, radar and navigation equipment falling within the scope of the R&TTE Directive.


ETSI groups in the Transportation cluster:

  • ERM (EMC and Radio spectrum Matters)
  • ERM TG 26 (Task Group Maritime)
  • ERM TG SRR (Task Group Automotive and Surveillance Radar)
  • ERM TG AERO (Aeronautics)
  • ITS (Intelligent Transport Systems)
  • RT (Railway Telecommunications)
  • SES (Satellite Earth stations and Services)

Standardization of Co-operative ITS is a global challenge and ETSI is collaborating with other standardization bodies in order to achieve worldwide interoperability and harmonized deployment.

In road transport many companies actively contribute to the standardization work - these include:

  • vehicle manufacturers
  • the automotive supply industry
  • silicon vendors
  • telecommunications network operators
  • research bodies
  • test houses

ETSI's aviation standards are developed by national regulators, air traffic management services, airport operators and aircraft manufacturers.

Much of the work performed in the cluster in support of European initiatives is done under Mandates issued by the European Commission and the European Free Trade Association (EFTA). The cluster also co-operates closely with various international organizations, including CEN, ISO, IEEE, SAE, IETF, ARIB, EUROCAE, EASA and ICAO to ensure harmonization and interoperability.


Intelligent Transport Systems

Our ITS committee (TC ITS) is leading the drive to achieve global standards for Co-operative ITS, which offers enormous potential through vehicle-to-vehicle and vehicle-to-roadside communication. Applications include road safety, traffic control, fleet and freight management and location-based services, providing driver assistance and hazard warnings and supporting emergency services.

We will fine tune our Release 1 standards, taking account of feedback received.

Release 2 will include new features and functionalities anticipated in future Co-operative ITS. In particular, it will include specifications to protect vulnerable road users such as cyclists and motor cycle riders, and for Co-operative Adaptive Cruise Control. It will also address platooning, a practice which is expected to save both fuel and space on the roads. Work is ongoing on the Co-operative Observation Service, whereby sensor information is shared between road users to, in effect, extend a driver’s field of vision, and we have initiated pre-studies into relevant use cases. We are addressing cross layer Decentralized Congestion Control for the management of Co-operative ITS.

We are also developing conformance tests, which are crucial for the commercial deployment of Co-operative ITS.

We are revising our Technical Specification (TS) on mitigation techniques to avoid interference between European CEN Dedicated Short Range Communication equipment and ITS operating in the 5 GHz frequency range.

We continue to address the spectrum requirements of Release 2.

Automotive Radar

In the Ultra Wideband automotive radar area, we are revising our Harmonised Standards for ground based vehicular radar in the 76 - 77 GHz range and high resolution automotive radar in the 77 - 81 GHz range in the light of the EC MOSARIM project on radar interference mitigation and the amended regulatory framework. We are developing a new European Standard (EN) on the use of helicopter radar to prevent accidents.


Work in response to EC mandate M/524 in support of the Single European Sky (SES) Air Traffic Management (ATM) Master Plan was discontinued in 2014 in the light of the EC’s restructuring of the SES and European Aviation Safety Agency regulations. However, the EC will still require our Community Specifications, at least temporarily.

We are therefore updating its two-part EN on the Advanced Surface Movement Guidance and Control System (A-SMGCS). We await clarification from the EC as to whether or not we should begin new work in support of M/524.

We are also extending our multipart EN on the A-SMGCS with a new part on multilateration equipment and we will revise our ENs for the ground-based VHF Digital Link Modes 2 and 4 radio transceivers for the aeronautical mobile service, in support of EC Mandate M/405 on ATM systems.

Our Aeronautics committee (TC AERO) was closed and work has been transferred to our committee ERM TGAERO.


Our Railway Telecommunications committee (TC RT) is working to resolve interference issues with public systems. We will update our TS on receiver parameters, specifically to deal with the introduction of 2W mobile handheld devices. We are developing a specification to incorporate Internet Protocol into the core network and interfaces.

We expect to complete a feasibility study into the use of GSM-R (GSM™ on railways) radio performance enhancements and resource optimisation to improve system capacity, spectrum efficiency and the robustness of the radio link. We are developing a new TS on the General Packet Radio Service (GPRS)/Enhanced GPRS features needed to operate the European Train Control System. We will work on a System Reference document on the spectrum needs for the roll-out of the Future Rail Mobile Communications System. We will also address the spectrum needs of urban rail, considering the sharing of ITS spectrum, and we will look into the possible adaptation of ITS standards and specifications for urban rail systems.


We are revising the Harmonised Standard on fixed and portable VHF equipment in the 121,5 - 123,1 MHz band for search and rescue purposes. We are updating our EN on Digital Selective Calling equipment and we are developing a new Harmonised Standard on maritime broadband radio links for ships and fixed installations engaged in off-shore activities.

Satellite transport

Our Satellite Earth Stations and Systems committee (TC SES) expects to publish a new EN on Earth Stations on Mobile Platforms (ESOMPs) operating with non-geostationary satellites in the Ka band. This will facilitate the introduction of new equipment for satellite broadband access on board aircraft and vessels. We are also developing standards aimed at adding new antenna types for ESOMPs operating with geosynchronous orbit satellite systems.
