Railway model
23
� At the end of 2006, the TETRA association (TETRA MoU) created the TETRA Rail Forum
� The goal is to analyse the railways’ communications requirements and decide whether the TETRA’s successful Metro model can be used for this industry or not
� Outside Europe TETRA is already a serious alternative to GSM-R; although there are also technological reasons the main one is economical => Coverage studies demonstrate
TETRA Rail Forum
24
main one is economical => Coverage studies demonstrate TETRA can cover the same area than GSM-R with the half base stations
� Next Steps for the TETRA Rail Forum:– To understand the railway industry requirements
– To define the additional supplementary services that might be needed
– To analyse the set of safety standards to be accomplished
– To define a roadmap of TETRA for railways applications
� Safety related electronic systems for signaling (EN 50129)
� Software safety (EN 50128)
� Key Concepts
– Safety Case (SC): 6 documents
– Safety Integrity Level (SIL): from 1 to 4 (*)
– 10-9 < SIL 4 < 10-8
Main ETSI Standards of applications in railways
25
– 10-9 < SIL 4 < 10-8
– 10-8 < SIL 3 < 10-7
– 10-7 < SIL 2 < 10-6
– 10-6 < SIL 1 < 10-5
� TETRA industry has started to apply for SIL certifications according
to Safety Cases
(*) THR (Tolerable Hazard Rates)
� TETRA achieves or improve the voice requirements of
Railways systems (i.e. Call setup < 300 ms)
� TETRA current data rate (i.e. 19200 bps packet data rate) is
more than enough for most of railway related applications.
TEDS (expected during this year) will provide a significant
higher bandwidth.
TETRA vs. GSM-R
26
higher bandwidth.
� TETRA works in 380-470 Mhz, requiring half the base stations
(cost effective)
� TETRA doubles the frequency efficiency (4 channels in 25
Khz)
� TETRA has proven its conformance with high speed mobile
operation, working at 574.8 km/h (ALSTOM, France, 2007)
� Professional Mobile Radio is dominant in transport today
� TETRA is the most implemented technology
� TETRA has proven to be the most adequate and cost effective technology for AVL, providing efficient voice and data communications with one communications system
� TETRA is suitable to support exploitation in Metros (Manual or Automated)
Conclusions
or Automated)
� TETRA allows to remotely control the trains, providing enhanced security, efficiency and cost effectiveness
� The new challenge for TETRA industry is to export its success in buses, trams and metro environments to railway industry.
