6G Spectrum Sharing Faces Technical and Economic Hurdles Despite Progress
Event summary
- 6G standardization efforts are underway, with the ITU identifying candidate spectrum bands for IMT-2030.
- ABI Research highlights the upper 6 GHz band and 7–8 GHz range as key areas for early 6G development.
- Spectrum sharing in the 6 GHz band is complex and costly, requiring significant investment to prevent interference.
- WRC-27 is expected to be a decisive moment for the future 6G frequency roadmap.
- China has allocated most of the 6 GHz band to cellular use, potentially influencing global 6G harmonization.
The big picture
The 6G spectrum landscape is evolving with the ITU and WRC identifying key bands for development. However, the technical and economic challenges of spectrum sharing, particularly in the contested 6 GHz band, pose significant hurdles. China's push for global harmonization around this spectrum adds a geopolitical dimension to the ongoing discussions, making WRC-27 a critical juncture for the future of 6G.
