Dynamic Spectrum Sharing 2.0 (DSS 2.0)
Sub-Millisecond 5G/6G Cross-Generational Spectrum Coexistence
Advanced spectrum sharing technology allowing 5G NR and 6G carriers to operate simultaneously within the exact same frequency band without interference.
Technical Explanation
Operators cannot afford to shut down 5G networks to deploy 6G. DSS 2.0 coordinates spectrum sharing on a sub-slot basis (under 100 microseconds). By utilizing deep learning traffic predictors, the base station dynamically allocates resource elements and antenna beams between 5G NR terminals and 6G UEs in real time, enabling smooth, zero-downtime generational spectrum migration.
Key Functions
- Shares spectrum dynamically between 5G and 6G terminals on a microsecond basis
- Eliminates the need for costly hard spectrum re-farming during the 6G rollout
- Protects 5G legacy synchronization signals while transmitting high-rate 6G packets
- Maximizes spectral utilization efficiency across evolving device ecosystems
