5G-PICTURE ICT-07-2017 Nº 762057

Demo objectives

Key Objectives:

• Demonstrate the performance of mmWave links (throughput, latency, jitter)

• Check the link behaviour on adverse weather conditions

• Build the new Train Access Network (TAN) architecture comprising mmWave, passive WDM and Ethernet aggregation technologies

• Demonstrate that TAN can be sliced to provide public services for passengers and railway operational services

Network Components

- Train Access Network (along the track) • mmWave APs along the track

• A passive WDM interconnecting the APs with fibre

• An Ethernet Aggregation Level to collect the data along a complete track

- Train Communication Network (on the train) • mmWave modems (front and rear)

• A 10G Ethernet ring along all train

• Service level equipment (Wi-Fi/CCTV)

5G-PICTURE Demo Location Train Details:

• Max speed 90 km/h • 3 vehicles (60 m total

length) • Capacity for 780

passengers

Service components: • Internet

Antenna Modules

A PCIe cable links each Antenna Module

on the roof with the corresponding Host

Processor Module inside the train

• Two units per train to

maximise mmWave

throughput and coverage.

• Each module contains a dual

antenna & dual baseband

unit

• Positioned as close to front

and rear of train as possible

for maximum trackside

visibility.

• Both train units include two

antennas. Forward facing

and rear facing.

• For maximum line of sight,

the train units should sit

proud of any other equipment

on the train roof.

Train Communication Network (TCN)

• One FGC train will be equipped with a TCN • Two on-board mmWave units, mounted at the front and rear of the train, with their Host Processor Modules

connected to both ends of a 10G Ethernet ring. • This 10G ring will be consist of three Ethernet switches interconnected (ADVA FSP 150CC-XG210); each of them

in a different vehicle • One Wi-Fi AP will be connected to each switch to provide Internet Access • CCTV cameras will be connected at some points of the TCN

Separation of masts < 2 * range + train length

Handover details

• Due to the movement of the trains, the connection between the mmWave on-board units and the trackside units will continuously change over time.

• This represents a problem for the network functionalities since the return paths of the packet replies dynamically change.

• Thus, it not possible to preserve network sessions if no handover management functions are implemented.

• Range in our case is 400 m 11

5G CTORINext steps and Large-Scale Demos

21/10/2019 14

Integration of commercially relevant, operational environments required for the demonstration of the large variety of 5G-VICTORI vertical and cross-vertical use cases

• Exploit extensively the existing ICT-17 5G infrastructures interconnecting main sites of all ICT-17 infrastructures:

• 5G-VINNI, 5GENESIS and 5G-EVE and the 5G UK test-bed 5G-VICTORI

Objective: common platform for Mission Critical (MC) voice and video and other MC rail-related data and signalling services addressing on-board and trackside elements.

• a softwarized end-to-end MC services solution that will enable the enhanced support of railway specific services

• A softwarized MC solution for rail environments enabling control and management of the on-board elements and trackside components (i.e. interlockings)
