Navigating the New Radio Regulations: ITU 2024 Updates and Their Impact on Global Communications

Published by Renair | March 2025

The International Telecommunication Union (ITU) made history in July 2024 with the release of updated Radio Regulations that took effect on January 1, 2025. These new regulations represent the culmination of four years of intensive negotiations during the World Radiocommunication Conference (WRC-23) in Dubai, attended by a record 3,994 delegates from approximately 150 ITU member states. For organizations operating in the global communications landscape, understanding these changes is not just important—it's essential for ensuring continued compliance and competitive advantage.

Understanding the Scale of Change

The 2024 Radio Regulations represent more than routine updates to technical specifications. They embody a comprehensive response to the rapidly evolving demands of modern telecommunications, addressing everything from 5G and 6G mobile communications to satellite networks, space exploration, and emerging IoT applications. The regulations provide the international framework that governs how radio-frequency spectrum and satellite orbits are allocated and used worldwide.

The significance of these changes cannot be overstated. Radiofrequencies power virtually every aspect of modern society—from the smartphones in our pockets to the satellites that enable global positioning systems, from weather forecasting networks to emergency communication systems. Unlike terrestrial networks that stop at national borders, radio waves propagate globally, making international coordination through the ITU essential for preventing interference and ensuring efficient spectrum use.

Key Changes in Spectrum Allocation

5G and Beyond: IMT Developments

One of the most significant updates involves spectrum allocations for International Mobile Telecommunications (IMT), which encompasses 5G and future 6G technologies. The new regulations identify additional frequency bands for next-generation terrestrial mobile services, including allocations in the 4400-4800 MHz, 7125-8400 MHz, and 14.8-15.35 GHz ranges.

These new allocations are crucial for supporting the growing demand for mobile broadband services and enabling the advanced applications that 5G and 6G promise to deliver. The availability of additional spectrum in these bands will help address capacity constraints in densely populated areas and support new applications requiring ultra-high data rates and ultra-low latency.

The 4400-4800 MHz band is particularly significant because it provides substantial bandwidth for 5G services while offering favorable propagation characteristics that balance coverage and capacity requirements. This band will be especially valuable for mid-band 5G deployments that need to bridge the gap between low-band coverage and high-band capacity.

Satellite Communications Evolution

The Fixed-Satellite Service (FSS) receives significant attention in the new regulations, with provisions for aeronautical and maritime V-band ESIMs (Earth Stations In Motion), small FSS antennas in Ku-band, and enhanced protection for radio astronomy in Radio Quiet Zones. These changes reflect the growing importance of satellite communications across multiple industries and applications.

New allocations for Non-Geostationary Satellite Orbit (NGSO) FSS in the 51 GHz band and FSS in 17 GHz for Region 3 provide additional capacity for satellite broadband services. These allocations are particularly important as LEO satellite constellations continue to expand and require additional spectrum resources to serve growing demand for satellite internet services.

The introduction of Equivalent Power Flux Density (EPFD) requirements for V-band FSS networks represents a significant step toward ensuring efficient and interference-free operation of multiple satellite systems in increasingly crowded orbital environments.

Mobile Satellite Services Expansion

The Mobile Satellite Service (MSS) benefits from several important updates, including allocations for MSS space-to-space links in 1518-2483.5 MHz and low-data-rate NGSO MSS in 1427-2025 MHz. Perhaps most significantly, the regulations address direct-to-device MSS connectivity in 694/698-2700 MHz bands, enabling satellite services to communicate directly with standard mobile devices.

This direct-to-device capability represents a paradigm shift in satellite communications, potentially eliminating the need for specialized satellite phones in many applications. The technology promises to provide satellite connectivity to standard smartphones and IoT devices, dramatically expanding the addressable market for satellite services.

Regional Considerations and Global Harmonization

The ITU divides the world into three regions for frequency allocation purposes: Region 1 (Europe, Africa, and Russia), Region 2 (the Americas), and Region 3 (Asia and Oceania). While the ITU aims for global harmonization, regional differences in spectrum allocation remain necessary to address local requirements and existing usage patterns.

The 2024 regulations include several region-specific allocations that reflect different regional priorities and constraints. For example, the 17 GHz FSS allocations for Region 3 address specific capacity requirements in the Asia-Pacific region, while certain frequency bands receive different treatment in different regions based on existing usage and interference considerations.

Understanding these regional differences is crucial for organizations operating globally, as equipment and services must be designed to comply with the applicable regulations in each region of operation.

Space Sustainability and Long-Term Planning

A notable addition to the 2024 regulations is Resolution ITU-R 74, which addresses space sustainability for long-term sustainable use of radio-frequency spectrum and associated NGSO satellite orbit resources. This resolution reflects growing international concern about space debris and the sustainable use of orbital resources.

The resolution calls for the creation of a handbook and ITU website page containing guidance on space sustainability practices. This initiative acknowledges that the increasing number of satellites and space missions requires careful coordination to prevent interference and ensure the long-term viability of space-based services.

For satellite operators and organizations using satellite services, these sustainability requirements will likely translate into new operational procedures and technical requirements designed to minimize the risk of creating space debris and interfering with other space operations.
