Specialist Task Force 390:
Receiver Performance: improved mobile receiver characteristics and test
procedures for GSM-R nearly interference free operation
Who we are:
Team Leader: Mr.
Dirk Schattschneider Deutsche Bahn AG
Team Members: Mr. François Deroche RFF
Mr. Kalle Tuominen OMNITELE LTD, behalf of Finnish Railways
Mr. Horst Fenske TRIORAIL GmbH & Co.KG

Dr. Massinissa Lalam SAGEM Communications SAS
What we do:
The STF 390 is dealing with the improvement of the GSM-R mobile receivers and
the corresponding test procedures to guarantee a nearly interference free
Since GSM-R is relevant to railway-safety specific regulations apply. This
includes the obligation under the directive 96/48/EC on the interoperability of
the trans-European high speed railway network and directive 2001/16/EC on the
interoperability of the conventional trans-European Railway network and the
related technical requirements specifications. Therefore, GSM-R is expected to
be in operation even beyond the year 2020-2025 timeframe.
Increasingly putting into operation GSM base stations in 900 MHz frequency band
beside the ER-GSM band causes interferences which are reported to affect
operation of GSM-R terminals in several European countries. Since several month
there are also interferences caused by placing UMTS in the frequency range above
the existing GSM-R frequencies in some countries.

Why we do it:
of the work is to achieve a better co-existence between the GSM-R and public
mobile services by providing standards for better mobile receiver performance
like amended blocking capabilities and IM3 interference response rejection.
How we do it:
The STF 390 will provide by the end of October 2010 an ETSI Technical
Specification on the improved mobile receiver parameters (blocking capability,
IM3, ACS, etc.) needed by GSM-R for nearly-interference-free usage in
- DTS/RT-EGSM-R-002 “Railway Telecommunications GSM-R improved
receiver parameters” (NWI)
To be published as version1.1.1.
The STF will produce the deliverables according to the following time scale:
TB adoption of WI 2009/07/08
Draft for approval 2010/09/17
WG approval (delete
if no WG) 2010/10/12
TB approval (RT#39) 2010/10/14
This specification will be based on existing 3GPP specifications and identifies
improved receiver characteristics and applicable test cases.
The work of the STF390 will also encompass a concept of internal or external
filters, installation requirements in railway trains for both receive and
The results of the work are also intended to be given to the 3GPP
standardization process to ensure compliance with the 3GPP specifications on
