Non-Terrestrial Networks (NTN)

Non-Terrestrial Networks (NTNs) are communication networks that utilize non-ground-based infrastructure, such as satellites and high-altitude platforms, to provide connectivity. These networks offer various advantages, including global connectivity, resilience, and faster deployment. NTNs can play a vital role in bridging the digital divide and enabling new applications across multiple industries.


There are two main types of NTNs:

1. Satellite Networks: Communication networks that use satellites orbiting Earth to provide communication services. Satellites can be in Low Earth Orbit (LEO), Medium Earth Orbit (MEO), or Geostationary Earth Orbit (GEO).
2. High Altitude Platform Systems: Platforms operating at altitudes of 20 - 50 km above the Earth's surface, carrying communication equipment. HAPS can be unmanned aerial vehicles (UAVs), balloons, or airships.

NTNs face challenges such as high costs, latency, and regulatory hurdles. However, they hold immense potential for revolutionizing global connectivity and enabling new applications in various industries. Notable NTN projects include SpaceX's Starlink and Alphabet's Project Loon.
