System concepts for HST-systems
For a suitable radio system concept in train applications, some key facts are
important:
1.
Track topology:
The radio coverage is highly dependant from the track topology and the track
environment.
2.
Tunnel:
How many tunnel sections/stations are to be considered for the track.
3.
Infrastructure:
What infrastructure is available alongside the track (e.g. masts, data network backbone,
power supply).
4.
Trains (number and configuration):
How many trains are to be considered? What kind of configuration they have?
5.
Data rate:
What is the mandatory data rate for all data services (peak/average).
6.
Availability/coverage:
Which availability and constant radio coverage is required in the overall system concept
to provide the data services.
TRainCom® radio system
PAGE 24
TELEFUNKEN Radio Communication Systems
Different infrastructure concepts
Some scenarios:
1. Worst Case:
No available infrastructure (green field approach). The complete TRainCom radio system must
be built up from scratch ( very low antenna mast distance < 2,5 km).
2. Bad Case:
No available infrastructure, but average mast distance is increased to a realistic value of 4 km.
3. Low Infra:
Antenna masts e.g. for GSM-R are partly available for antenna installation. Additional masts
and complete cable infrastructure must be built up. (Mast distance ~ 4 km)
4. Medium Infra:
Available masts and cable infrastructure. Some additional masts and Infrastructure to be
considered.
5. Good Infra (like GSM-R):
Sufficient available infrastructure (Mast, Power and Backbone) useable for TRainCom, due to
similar radio propagation like GSM-R.

Conclusion

By using available infrastructure the invest costs (CAPEX) for
TRainCom can be significantly reduced.

The TRainCom radio system provides real broadband radio links for
passenger and operational data services simultaneously. Its capability
can be used to provide additional services (advertisement) to refinance
its costs.

Increasing passenger figures by improved train attractivity will generate
additional revenues.

The TRainCom system concept provides additional potential/resources
for future growth.

Usage of a hybrid radio solution with narrow band services (e.g. GSM)
is recommended to extend the services into low density areas or to
cover ancillary tracks.

Conclusion on hybrid solutions

TRainCom HST radio systems are optimized for various passenger data
services including high volume applications and can also support all
services of the train operator.

Due to acceptable costs for the low volume data transmission and the
wide coverage of the GSM network, a hybrid system part is an ideal
partner to complement data services of a TRainCom radio system.

Further it will also enable a rapid coverage of the entire rail network of a
rail operator at least with a with a basic system performance, prior to the
implementation of TRainCom system parts.

For all low traffic rail tracks (e.g. ancillary tracks) a hybrid GSM service is a
very cost effective solution.

TRainCom HST complements a public network in critical areas where no
coverage is given (e.g. tunnels, stations, etc.)

HST- simple business model
Hypothesis:
Every passengers pays 1 additional Euro per ticket (= 2%).
(Assumption Ø Ticket price = about 50.- € / 250 km)
Calculation:
Daily usage 100.000 passengers
100.000 Pax * 360 Tage * 1 € = 36 Mio. € / p.a.
With 36 Mio. € per year and an average interest rate of 8%
you can finance
about 400 Mio. € invest.
