What is NTN?

Non-Terrestrial Networks (NTN) typically refer to communication networks that do not rely solely on traditional terrestrial infrastructure, such as land-based cellular towers or fiber optic cables. Instead, NTN leverages various non-terrestrial technologies and platforms to provide connectivity.

Here are some key elements and examples of NTN:

• Satellite Networks: One of the most common forms of NTN is satellite communication. Satellites in geostationary orbit or in lower Earth orbits (LEO) can provide broadband internet access, telecommunication services, and data connectivity to remote and underserved areas.
• High-Altitude Platforms (HAPs): HAPs are platforms that float at high altitudes in the Earth’s atmosphere, such as stratospheric balloons or solar-powered drones. They can serve as relay stations for wireless communication and internet access.
• Aerial Platforms: Some NTN solutions use drones or other aerial vehicles equipped with communication equipment to create temporary communication networks, especially in disaster-stricken areas or during events where traditional infrastructure is insufficient.
• Underwater Communication Networks: While not always included in the term NTN, underwater communication networks are another example of non-terrestrial connectivity. These networks are used for applications such as oceanographic research, underwater surveillance, and offshore energy operations.
• Hybrid Approaches: Some NTN solutions combine various technologies, such as a combination of satellites and high-altitude platforms, to extend network coverage and improve reliability.
