RT is Responsible for those aspects of Global System for Mobile
communications (GSM ™) standardization which are specific to Railway and
Private Mobile Radio (PMR)operations (GSM-R).
The GSM-R standard implements a number of applications and requirements
specific to the railway environment, which use the common GSM platform.
Thirty two members of the Union Internationale des Chemins de Fer (UIC) have
signed a Memorandum of Understanding (MoU)supporting GSM-R for their radio
GSM-R has now been selected by nearly all the European railways.Eighteen
railways have already signed an Agreement of Implementation (AoI) to start
implementation of the essential requirements,and additional countries in
Eastern Europe and around the world are backing this ETSI standard.
Supported by a group of specialists and funded by its railway and
industry members,ETSI Technical Committee Railways Telecommunications is
continuing the work of ETSI's former Special Mobile Group, that accomplished
the original standardization of GSM-R. TC RT's main task is to maintain the
specifications for the use of GSM to meet the requirements of the railways,
and to update and develop the existing ETSI standards in response to
relevant European Directives. This will include the use of the General
Packet Radio Service (GPRS) in railway applications, and its
interoperability with GSM-R. In addition, first implementations have raised
issues on specifications and roaming for international trains, which are
currently being addressed. Work is well underway, and several Change
Requests have been issued to improve the operation of the GSM-R system and
to answer the needs of users.
TC RT has investigated the huge potential for the application of GSM-R
world-wide and presentations were made in Europe, the US and China.
In the future, in collaboration with the railway industry, TC RT will
continue to improve the GSM-R standards and to meet the developing need for
harmonized international communications for trains crossing European
borders. New requirements from users in Europe and world-wide will also be
