- 5G NTN expands connectivity through low-, medium-, and high-orbit satellite networks.
- It offers global coverage, low latency and greater communication resilience.
- It will be applied in IoT, transportation, emergencies and smart cities.
- It faces challenges such as spectrum optimization and cost reduction.
Global connectivity is constantly evolving and the 5G NTN (Non-Terrestrial Networks) plays a crucial role in this revolution. This technology seeks to extend coverage beyond terrestrial networks, reaching remote places where traditional mobile signals do not reach.
Thanks to the combination of terrestrial and satellite networks, the 5G NTN will allow for a more seamless connection experience reliable, even in rural, maritime and air areas. But how exactly does it work and what are its main applications? Let's find out in detail.
What is 5G NTN?
The term NTN (Non-Terrestrial Networks) refers to telecommunications networks that operate beyond the earth's surface. This includes the use of satellites in low (LEO), medium (MEO) and geostationary (GEO) orbits, as well as high altitude stations (HAPS) and drones.
El 3GPP (the body that defines mobile communications standards) has worked on integrating 5G NTN to make it compatible with conventional devices, so that the Units can connect directly to satellites without the need for hardware additional.
Advantages of 5G NTN
The use of non-terrestrial networks offers multiple benefits that will impact both individual users and industrial sectors.
- Global coverage: It will enable connection at any point on the planet, including rural, maritime and air regions.
- Low latency: Thanks to low orbit satellites (LEO), latency is drastically reduced compared to traditional satellites.
- Greater resilience: It complements terrestrial networks, ensuring connectivity in the event of natural disasters or failures in terrestrial infrastructure.
5G NTN Use Cases
Technology 5G NTN will transform several industries. Some of the most notable applications include:
- IoT and smart cities: Constant connectivity for sensors and IoT devices anywhere.
- Transport connectivity: Crucial for aviation, maritime navigation and autonomous vehicles.
- Emergency management: Communication guaranteed in natural disasters and hard-to-reach areas.
5G NTN Challenges
Despite its advantages, this technology faces significant challenges:
Radio spectrum optimization: Availability frequency bands adequate is key to efficient operation.
Cost reduction: The manufacturing and launching of satellites It remains expensive, which may affect its popularization.
Interoperability: Full compatibility between terrestrial and satellite networks is required to ensure seamless connection.
Everything indicates that the commercial deployment of 5G NTN will become a reality in the coming years, improving global connectivity and expanding communication possibilities in key sectors.
