Executive Summary
The present document describes the spectrum requirements for the following communications of urban rail systems:
• primarily trackside/infrastructure-to-train communications; and
• optionally train-to-train communications.
Standardisation work is currently ongoing in the ESOs related to EC mandate M/486 EN "for programming and
standardisation addressed to the European Standardisation Bodies in the field of Urban Rail" [i.12]. The rationale for
this mandate from the European Commision is to reduce the greenhouse gas emissions, which come for a large portion
from urban areas and urban transport. Urban rail is seen as one of the prominent solutions to offer the public other ways
of transportation while supporting a modal shift from private car and increasing demand for public transport thanks to
the economies of scale and to the administrative simplification.
In addition, since the European rail industry is a world leader, the technical harmonisation of urban rail would be
beneficial not only from the environmental point of view but also from the competitiveness point of view.
The spectrum requirements cover the needs for:
1) fundamental time-critical CBTC and safety relevant applications with very low latency; and
2) non-safety relevant applications, applying mobile networking based on internet protocol as well as other
protocols, extending the applicability of the communications equipment towards railway traffic management
tasks and other applications.
Both of these types of applications might indirectly enhance the traffic safety and system operation.
ETSI
6 ETSI TR 103 111 V1.1.1 (2014-10)
CBTC is providing automatic train control with or without driver. To drive automatically a train, a Data
Communication System is needed. When trains are moving the wireless system allows communication with a central
system. The wireless system is used to transmit traction order or breaking order in a safe mode. If trains cannot transmit
messages, they will not be authorized to move.
Each train sends its location 5 times a second and the central system sends an authorization to move for each train in the
line. All the messages use the wireless DCS. This system allows to reduce the time between trains in automatic mode
(85 s instead of 105 s with human drivers)
It is recommended to have contiguous and/or nearby frequency bands, in the upper 5 GHz frequency range designated
for items 1 and 2. It is proposed:
• for item 1: to designate 20 MHz of spectrum for CBTC and safety relevant critical applications, preferably
within the frequency range from 5,905 GHz to 5,925 GHz;
• for item 2: to designate 20 MHz of spectrum, i.e. 5,855 GHz to 5,875 GHz, for non-safety related urban rail
applications (secure control, railway traffic management and video-surveillance).
It also requested to consider in a future review of the proposed ECC Decision the designation of 5,925 GHz to
5,945 GHz for future Urban Rail applications.
Spectrum usage as proposed in the present document is to be considered on a pan-European basis. In addition to the
benefits expected from technical harmonization, the aim is to avoid coordination/protection zone issues at borders, and
to facilitate any deployment in urban areas crossing borders.
Introduction
The present document has been developed to support the co-operation between ETSI and the Electronic
Communications Committee (ECC) of the European Conference of Post and Telecommunications Administrations

4 Comments on the System Reference Document
4.1 Statements by ETSI Members
Comments from TC ITS:
During the commenting phases of the present document, one important comment regarding using the same protocol as
ITS-G5 was not answered.
TC ITS would like to point out that the proposed spectrum (5 915 MHz to 5 935 MHz) overlaps with spectrum currently
assigned to ITS-G5 (see ECC DEC(08)01 [i.1], 5 915 MHz to 5 925 MHz). This spectrum is to be used for safety-
related ITS services.
It is clear that Urban Rail systems and ITS coexist geographically. This raises the issue of coexistence in the 5 915 MHz
to 5 925 MHz band. Noting that this band is reserved for ITS
