Which technology enables dynamic spectrum sharing between 4G and 5G on same frequency band?
- Carrier Aggregation
- DSS
- MIMO
- Beamforming
Answer: DSS
DSS (Dynamic Spectrum Sharing) allows 4G LTE and 5G NR to coexist on same frequency band by dynamically allocating resources based on real-time demand. Enables faster 5G rollout using existing spectrum without refarming. Trade-off: slight capacity reduction vs accelerated coverage. Key for operators transitioning from 4G to 5G.
