Marketing – acting as a beacon in the 5G satellite R&D community and beyond, towards terrestrial players


Critical Technology Elements CTE Approach

5G NR Simulation

Harmonized proxy node Integration of the satellite network as 5G access (demonstrated as untrusted non-3GPP)

Backhaul carrier aggregation Management of the multiple available backhaul links

Dynamic data paths support Adding more UPFs, data path selection, re-selection and handover scenarios, Chaining of SMFs

Automatic management of remote nodes Providing a solution for the automatic management of a large number of edge nodes

Support for on the move communication Careful control of intermittent backhauls

Convergence layer adaptation Adapting the convergence layer for the specific communication

5G multicast support Providing a new solution for the broadcasters

Background bearers support Providing connectivity to edge caches with background bearers

Security and privacy Providing security apps to the edge nodes, securing the edge nodes themselves

Validation Use Cases

11

UC1 – video delivery

UC2 – video and IoT content acquisition

UC3 – NB-IoT

UC4 – LoRA

UC5 – eMBB

UC6 – direct connectivity

UC7 – nomadic and mobile node

UC8 – NTN NR (simulation)


Video Delivery

12

Conclusion: The use case behaved as expected


NB-IoT, LoRA, IoT content acquisition

13

Due to the specific transmission model, the satellite connectivity did not impact the communication

Delay in the expected range (no constraints considered by the applications)

No perceived limitation due to the size of the data packets


Video Acquisition

14

A very strong transcoding was needed in the edge node to fit the satellite connectivity uplink (~3Mbps)

A delay of 2 seconds was perceived in the connectivity


Direct connectivity

15

Due to the specifics of the NTN base station, two core networks were used (OTT over the satellite network)


Nomadic and mobile node

16

Forward link Return link

Data rate Dresden in Mbits/s 4.51 5.10

Data rate Erlangen/Ilmenau in Mbits/s 14.7 7.73


SATis5 Use Case Validation

17

Each of the use cases were validated separately

The Satellite link is very stable (with expected jitter)

None of the use cases presented anomalies

Use cases were in the expected target range (i.e. worked)

Unexpected: very complex process to establish a new terminal

Complicated acquisition of radio equipment + modem

Highly complicated deployment


Successful SATis5 demonstrations
