❓ Frequently Asked Questions
What is Terahertz (THz) in wireless communications?
THz refers to frequencies roughly 0.1–10 THz. This band offers very wide bandwidths for ultra-fast wireless links, typically over short ranges and line-of-sight paths. It’s an active research area due to hardware and propagation challenges.
What are the main challenges of terahertz links?
Key challenges include strong atmospheric absorption (water vapor and oxygen), high path loss, weather effects, and current limitations in THz transceivers, antennas, and beamforming.
What are Non-Terrestrial Networks (NTN)?
NTN uses satellites and high-altitude platforms (e.g., balloons or aircraft) to provide connectivity and backhaul, extending coverage beyond ground-based networks.
How do NTN and terrestrial networks complement each other?
NTN expands coverage to remote or disaster zones and provides backhaul, while terrestrial networks deliver high-capacity local access. Integration requires managing latency, mobility, Doppler effects, and spectrum coordination.
