FAQ's

Does 3GPP support 5G/6G deployments over Non Terrestrial Networks?

The 3GPP 5G NR standardization has already standardizes the 5G/6G non-terrestrial communication in Releases 16, 17, 18 and lately 19, to reach mass markets due to higher interoperability.

What are the benefits for 5G NTN?

The benefits are the expected huge increase in the number of potential customers in rural and urban areas with low or no reachability from the terrestrial 5G, and the opportunity to tap into a more developed, high-volume supply chain, saving development time and costs.

What are the main 5G NTN over satellite Network challenges?

The main challenges are the integration of 5G NTN services into existing network infrastructure for maximized performance, the future system configuration to support new business cases, the number of devices to register in one satellite mMIMO beam, the simultaneous scheduled and transmitting devices in one beam in a specified time period and the planning capacity question on the optimal usage of available capacity based on chosen system configurations.
