Abstract
This paper provides technical and economic analysis supporting spectrum identification for 6G at the World Radiocommunication Conference 2027 (WRC-27). We quantify the spectrum needs for 6G in the 7-15 GHz upper mid-band range, projecting that 2-4 GHz of contiguous bandwidth is needed per operator for 6G deployment. Our coexistence studies with incumbent services (satellite, radar, fixed links) show that sharing is feasible with appropriate protection zones. Economic analysis estimates that timely spectrum allocation would generate $800B in cumulative GDP impact by 2035.
AI Summary
- Technical and economic analysis for 6G spectrum at WRC-27.
- 2-4 GHz contiguous bandwidth needed per operator in 7-15 GHz band.
- Coexistence with incumbent services feasible with protection zones.
- $800B cumulative GDP impact from timely spectrum allocation by 2035.
Key Findings
- 17.125-8.5 GHz is the most globally harmonizable segment for initial 6G deployment.
- 2Contiguous wide bandwidth is essential for 6G high-capacity use cases.
- 3Delayed spectrum decisions could cost the industry $200B in lost innovation.
Industry Implications
National regulators should actively support 6G spectrum agenda at WRC-27.
Industry must provide sharing studies to address incumbent concerns.
Early certainty on spectrum enables timely equipment development.
