TN-NTN Convergence Node
Dual-Stack Terrestrial/Satellite Anchor
A core network anchor that combines terrestrial cellular towers and LEO satellite links into a single unified data pipe for user devices.
Technical Explanation
Rather than treating satellite and terrestrial mobile networks as separate SIM cards or disconnected services, the TN-NTN Convergence Node unifies them. If a user is walking through an urban downtown, traffic flows over terrestrial Sub-THz micro-cells; the instant they enter a rural valley or national park without towers, traffic seamlessly transitions to an overhead LEO satellite without interrupting an active video call or resetting TCP sessions.
Key Functions
- Seamless multipath bonding and packet switching between terrestrial cells and LEO satellites
- Zero-latency handover transition when leaving terrestrial cellular coverage zones
- Single unified subscriber profile and authentication credential for both satellite and ground
- Dynamic multipath aggregation combining satellite and terrestrial bandwidth simultaneously
- Ubiquitous 100% geographic coverage spanning remote wilderness, oceans, and urban centers
