Study on feasibility of SATCOM for railway communication

Final Report
B.3 QOS PERFORMANCES
This section aims to investigate the QoS performances provided by solutions available on the market
for mobile environments (i.e. SOTM technology), paying special attention to typical railway channel
impairments.
11. (SATCOM) Are your products suitable to operate in a railway environment taking into account
that they have to provide countermeasures against the typical impairments for this type of channel
a. Doppler (e.g. train speed of up to 350 km per hour)
b. Fast fadings (e.g. periodic micro cuts due to posts)
c. Slow fadings
d. Multipath (e.g. due to the catenary reflection when omni antenna is employed)
e. Off-axis regulation due to the need for low profile antenna
f. Others (please specify):
12. (SATCOM) What products and/or services do you offer for this type of environment or similar?
a. Baseband equipment (modems, routers, etc)
b. Planar/low profile antennas and/or RF (e.g. ACU, BUC, LNB, etc) devices for remote
terminals
c. Satellite constellation (e.g. LEO, GEO)
d. Satellite ground stations
e. Others (please specify):
Can you indicate the name of the technology/product or service that you offer:
13. (SATCOM) Do you use a standardised air interface?
