WRC Spectrum Harmonization
ITU World Radiocommunication Conference Allocations
The international regulatory treaty decisions governing which Sub-THz, FR3, and satellite frequency bands are globally harmonized for 6G.
Technical Explanation
Without global spectrum harmonization, mobile phone manufacturers would need to build dozens of regional hardware variants, raising costs and breaking international roaming. The ITU World Radiocommunication Conferences (WRC-23 and WRC-27) coordinate international spectrum treaties, identifying specific frequency bands (including 7.125-8.4 GHz, 14.8-15.35 GHz, and Sub-THz windows between 100-275 GHz) as globally harmonized allocations for IMT-2030.
Key Functions
- Global regulatory treaty decisions defining international frequency band harmonization
- Enabling single-SKU global smartphone manufacturing and seamless worldwide roaming
- Protecting passive radio astronomy and Earth exploration satellite services from interference
- Defining power limits and spectral emissions masks for commercial 6G transceivers
- Coordinating coexistence between terrestrial mobile networks and non-terrestrial satellite constellations
