Technology offers multiple technical solutions and standards

Today we can state that it is possible to meet ALL the requirements but …..

…….. at the condition that we aim to just one

There is no global end-to-end management

Each one for himself

Separated in the big family of telecommunications4

Actual telecommunication requirements of a railway operator concern both the rail infrastructure (rails, trains, monitoring devices, level crossing, exchanges, etc.) needing different data rates and the several fixed premises needing broadband communications and each one needs different QoS

The Railway system is a (very) complex system and as such its telecommunication requirements cannot be satisfied by just one technology

Railway infrastructure partially covered by one single system

Even where covered not always the required performance for some kind of services are guaranteed

• Bandwidth• Flexibility• QoS• Security

The integration of different systems can guarantee the best performance for a meaningful set of services

Generation Technology

1 Analogue

2 Digital, circuit switching, narrow band (GSM)

3 Digital, circuit and IP packet switching, wide band (UMTS)

4 Larger bandwidth and data rate (LTE)

5 Larger bandwidth, SDN, NFV, lower power consumption, billions of connections

1. compute and storage services provision • distributed computer, with processes and applications

dynamically created, moved, deleted

2. explosion of IoT and M2M comms• effective authentication, naming, addressing, routing

and related functions for a vast number and kind of terminals

3. vertical sectors (Automotive, Industry 4.0, Entertainment, Energy and E-health)

• transport and computing services as virtual distributed computers under complex SLAs

• 1000 times higher mobile data volume per geographical area.

• 10 to 100 times more connected devices.• 10 to 100 times higher typical user data rate.• 10 times lower energy consumption.• End-to-End latency of < 5ms.• Location precision < 3m• Mobile speed up to 500 km/h• Ubiquitous 5G access including low density areas.

2025 deadline to cover big cities and transport infrastructures

Costs independent on distance (within one satellite coverage)

Collecting and broadcasting characteristics

Particularly suitable and cost effective for multicasting

• Disruptive to feed CDN nodes

• Efficient to distribute security keysIrreplaceable in areas with scarce or no infrastructures

Irreplaceable in case of disaster

Suitable for large coverage areas and long range mobility

Relatively short deployment time

Flexible architecture

Bypass very crowded terrestrial networks

With the same infrastructure both fixed and mobile services

• Disruptive to feed CDN nodes

• Efficient to distribute security keys

to being the element that can

meaningfully contribute to

achieve the “zero latency” and to

efficiently face the multi-domain issue

From being a problem due to

delay

9

Advantages• Large coverage areas

• Flexibility in bandwidth utilization

• Cost/technical effectiveness for broadcast and multicast

• Coverage in areas not covered by terrestrial networks

• Low impact of Doppler effect

• Same infrastructure for signaling and data

Disadvantages• High delay

• Big terminals

• Terminals and service costs

Applications

• Rail communications

• Mobile Internet Access

• Support to the broadband fixed network– Remote locations, construction sites, infrastructure

monitoring, level crossing

– Broadcast and multicast services10

Architectures• Hybrid terrestrial-satellite

• Mobile Infrastructure (satellite far from urban areas and stations, terrestrial otherwise)

Protocols• TCP Noordwijk or Wave

• Optimized BoD

• Caching

• DTN

• SPDY

• Fixed Infrastructure (satellite in areas not covered by terrestrial and to feed the ICN and CDN)

Athena-Fidus (Access on THeaters for European allied forces Nations-French Italian Dual Use Satellite) is a French-Italian telecommunication satellite providing high-throughput communications in “dual use”: military and civil.

The satellite provides an overall 3 Gbit/s throughput, using mostly Ka-band links. It carries 14 antennas including 7 mobile spot antennas, enabling positioning of steerable 1750 km diameter spot beams over operational theatres requiring a high bandwidth.

Innovative system based on geostationary satellite

Services in a new governmental frequency band (EHF/NATO Ka band) and in civil Ka band

Civilian telecommunication standards (DVB RCS and S2) allowing high telecommunication capacities, for civilian and commercial applications

Launch 2013, position: 37.8° E

All-IP platform, Small user antenna, bi directional communications

Example of Ka-band spot over Italy, up to 2 Mbit/s uplink and 20 Mbit/s downlink
