DYNASAT will showcase its live demonstrations at MWC 2023, the world’s largest and most influential connectivity event.

As part of the DYNASAT Consortium, Magister will be participating in this year’s Mobile World Congress (MWC) in Barcelona from February 27 to March 2 – the world’s largest and most influential connectivity event. We will be contributing by demonstrating and providing first-hand information at booth 5H80 in two of the four demos DYNASAT will be presenting. Read here what to expect:  
DYNASAT partners Fairspectrum, Magister Solutions, and Thales Alenia Space France will host four demonstrations on

  • Dynamic Spectrum Access (DSA) for Non-Terrestrial Networks (NTN) – Terrestrial Network (TN) sharing
  • assessing 5G NTN Low Earth Orbit (LEO) satellite constellation user link capacity at the system level
  • multi-connectivity for 5G NTN and TN scenarios
  • Coordinated DSA (C-DSA) for improved use of the radio frequency spectrum

The last two of the demonstrations listed above will be undertaken by Magister, while our DYNASAT partners Fairspectrum and Thales Alenia Space France will be conducting the first and second respectively. All four evaluate new techniques for bandwidth-efficient transmission and more efficient spectrum use for satellite architectures. The results will ensure a fully integrated satellite network infrastructure – essential for both professional 5G user equipment and the mass-market.

More about the four DYNASAT demonstrations here.

MULTI-CONNECTIVITY FOR 5G NTN

  • Multi-Connectivity (MC) for throughput/reliability enhancement between Non-Terrestrial Networks (NTN) and NTN/Terrestrial Networks (TN).
  • How MC node addition and traffic steering algorithms have been designed.
  • How the system architecture (measurements, signalling, and scenarios) has been designed to make optimal use of MC.
  • How MC can optimize the use of resources via dynamic traffic steering and provide throughput enhancements.

COORDINATED DYNAMIC SPECTRUM ACCESS

 

  • How the required measurements, signalling, and system architecture are designed.
  • How the frequency spectrum is limited according to each system’s current needs.
  • How effectively satellite connectivity can extend coverage where TN connectivity is not possible or financially feasible.
  • The benefits of using C-DSA over static methods of coordinated sharing.

“MWC is our last public demonstration of the DYNASAT project before it finishes at the end of March 2023” Magister’s CEO, Jani Puttonen, explains before then plunging into greater detail about the two Magister demos.

“In the multiconnectivity demo, we are looking at how mobile terminals on the ground (and possibly VSATs in the future) can be connected to both TN and NTN 5G, and can access both networks simultaneously to optimise their performance. In the C-DSA demo, we are showing how TNs and NTNs can use the same frequency band by means of a dynamic controller, which is continuously assessing how much of the spectrum should be assigned to each network”.

“The idea is that the satellite complements the terrestrial network”, Jani adds, implying that the C-DSA will always give precedence to the terrestrial network. “So if the TN is only half using the spectrum of a frequency band then the remaining spectrum on that band is allocated to the satellite”.

ABOUT MWC

With over 2000 leading companies attending this year, MWC Barcelona is a key networking opportunity for the mobile and tech industries, attracting some of the most influential decision-makers who will be sharing their insights on future connectivity trends.
