Last updated on 


World Radiocommunication Conference 2019 (WRC-19)

The World Radiocommunication Conference 2019 (WRC-19) was the 2019 session of the international conference organized by the International Telecommunication Union (ITU). It took place from October 28 to November 22, 2019, in Sharm El Sheikh, Egypt. WRC-19 was a significant event in the field of radiocommunications as it reviewed and revised the international Radio Regulations, which govern the use of the radio-frequency spectrum and satellite orbits worldwide. The decisions made at WRC-19 had a substantial impact on the allocation and use of spectrum for various communication services and technologies. Let's explore the key topics, outcomes, and significance of the World Radiocommunication Conference 2019.

Key Topics and Agenda Items at WRC-19:

WRC-19 addressed a wide range of topics related to radiocommunications and spectrum management. Some of the key agenda items included:

  1. 5G Spectrum Identification: WRC-19 identified additional frequency bands for International Mobile Telecommunications (IMT), commonly known as 5G, to support the deployment of fifth-generation mobile networks.
  2. High-Altitude Platform Stations (HAPS): The conference considered regulatory provisions for HAPS, which are airborne platforms that operate in the stratosphere and provide communication services.
  3. Artificial Intelligence (AI) for Spectrum Management: WRC-19 discussed the potential use of AI and machine learning techniques for efficient spectrum management.
  4. Earth Exploration-Satellite Services (EESS): The conference addressed issues related to the protection of the Earth exploration-satellite service (passive) from interference by other services.
  5. Radio-Frequency Identification (RFID): WRC-19 reviewed the frequency bands for RFID systems, which are used for identification and tracking of objects.
  6. Satellite Constellations: The conference considered the deployment of mega-constellations of non-geostationary-satellite orbit (NGSO) satellites for global internet connectivity.
  7. Aeronautical Telemetry: WRC-19 reviewed the frequency bands for aeronautical telemetry systems used for testing and monitoring aircraft.

Outcomes and Decisions:

The decisions made at WRC-19 had significant implications for the telecommunications industry and various communication services. Some of the notable outcomes of the conference were:

  1. Additional 5G Spectrum: WRC-19 identified several frequency bands for 5G deployment, including the 24.25-27.5 GHz, 37-43.5 GHz, and 66-71 GHz bands, to meet the growing demand for mobile broadband services.
  2. Regulations for HAPS: The conference established regulatory provisions for the deployment and operation of High-Altitude Platform Stations, which are seen as a potential solution for providing broadband connectivity to remote areas.
  3. NGSO Satellite Constellations: WRC-19 addressed the coordination and protection of the radio-frequency spectrum for mega-constellations of NGSO satellites, ensuring interference-free operations.
  4. Protection of Earth Exploration-Satellite Service: The conference adopted measures to protect the passive Earth exploration-satellite service from interference, ensuring the continuity of vital remote sensing and scientific observations.
  5. AI for Spectrum Management: WRC-19 recognized the potential of AI and machine learning in spectrum management, paving the way for more efficient and dynamic allocation of radio-frequency resources.

Significance and Impact:

The decisions taken at WRC-19 have a lasting impact on the global telecommunications landscape. By identifying additional spectrum for 5G and other communication services, the conference supported the deployment of advanced technologies and enabled enhanced mobile broadband, IoT connectivity, and future innovations. Moreover, the regulatory provisions for HAPS and NGSO satellite constellations fostered the development of new communication solutions for bridging the digital divide and expanding connectivity to underserved areas.

The protection of critical services like Earth exploration-satellite and aeronautical telemetry ensures the continuation of scientific research and aviation safety. Additionally, recognizing the potential of AI in spectrum management opens up new possibilities for optimizing spectrum usage and accommodating the growing demand for wireless services.

In conclusion, the World Radiocommunication Conference 2019 (WRC-19) was a pivotal event that reviewed and revised the international Radio Regulations, shaping the allocation and use of the radio-frequency spectrum and satellite orbits globally. The decisions made at WRC-19 set the foundation for the continued advancement of communication technologies, the expansion of 5G networks, and the development of innovative solutions to meet the evolving needs of the telecommunications industry and society as a whole.
