5G non-terrestrial networks (NTN)
5G NB-IoT and direct-to-device satellite connectivity
Non-terrestrial networks (NTN) are wireless communication systems that operate above the Earth's surface, utilizing satellites in low Earth orbit (LEO), medium Earth orbit (MEO) and geostationary orbit (GEO), as well as high-altitude platforms (HAPS) and drones. These components play a crucial role in providing seamless coverage, extending connectivity to remote areas without access to traditional terrestrial networks. Currently, devices are categorized based on their connection to either 3GPP terrestrial networks or satellites, requiring separate devices for satellite connectivity. NTN aims to integrate all mobile devices into a unified 3GPP ecosystem, connecting them seamlessly to both terrestrial and satellite networks.
Key topics for NTN:
- Direct-to-device satellite connectivity
- NTN operator perspective
- 5G NB-IoT coverage extension for delay and disruption-tolerant networking
- Unified and resilient 3D networks
- NTN device testing solutions
