DVB-S2X, DVB-RCS2, DVB/5G NR performance

Customer Perspectives

“Magister Solutions’ simulators will allow us to simulate and improve our 5G NB-IoT constellation and optimize QoS.

Thanks to their platform, we will be able to model critical scenarios, including our store & forward capability, ensuring reliable messaging in areas without terrestrial coverage.”

Marco Guadalupi

CTO & co-founder, Sateliot

“We received a recommendation from the European Space Agency (ESA) to use Magister’s help for simulating 5G NR over satellite.

The project with Magister helped us better understand how 5G NR would work in a NTN context. The main takeaway is a more complete understanding of how 5G NR compares to traditional DVB technologies for SatCom.”

Edvin Lindqvist
CTO, Forsway

“We knew DVB’s specifications for NGSO satellite constellations promised impressive performance, but we didn’t know quite how impressive until we commissioned a set of simulations from Magister Solutions.

These in-depth system-level simulations compared the performance of DVB-S2X and DVB-RCS2 to NR-PUSCH, the return link standard for transmitting data from mobile devices back to the network in a 5G New Radio (NR) environment.”
