World Radiocommunication Conference (WRC)

The World Radiocommunication Conference (WRC) is a global event organized by the ITU-R to review and revise the Radio Regulations, the international treaty governing the use of the radio-frequency spectrum and satellite orbits. Held every three to four years, the WRC brings together regulators, governments, industry, and other stakeholders to harmonize spectrum use and enable the development of new wireless technologies.

Purpose and Scope

WRC conferences serve to:

• Allocate and reallocate frequency bands for specific services (e.g., mobile, satellite, radar, broadcasting)

• Revise technical and operational provisions of the Radio Regulations

• Address interference mitigation and coordination procedures

• Establish EIRP/ERP limits, protection zones, and sharing frameworks

• Define regulatory frameworks for emerging technologies such as 5G, satellite broadband, and high-altitude platforms

Examples of WRC Outcomes

• WRC-15: Harmonized 700 MHz band for mobile broadband globally

• WRC-19: Allocated additional spectrum for 5G in the 24.25–27.5 GHz band

• WRC-23: Reviewed satellite regulations, including NGSO coordination and ESIM (Earth Stations in Motion) rules

• WRC-27 (planned): Expected to address spectrum for 6G, IoT, and AI-driven spectrum access

Relevance for Manufacturers and Test Labs

WRC decisions influence national and regional regulations that govern:

• Device compliance requirements (e.g., maximum EIRP, channel plans)

• Certification conditions for RF and satellite products

• Market access rules across different ITU regions

• Test parameters in harmonized standards such as ETSI EN 301 908 or EN 303 413

Understanding WRC outcomes is essential for product developers, compliance managers, and regulatory bodies when planning spectrum strategies and ensuring forward compatibility.
