The latest National Frequency Plan update reflects significant regulatory changes aligned with the International Telecommunication Union’s (ITU) WRC-23 decisions. Notably, this revision introduces stricter compliance obligations and redefines how spectrum is allocated and managed. As a result, stakeholders across telecommunications must carefully evaluate how these changes affect equipment design, deployment, and spectrum usage.
Shift to Mandatory Compliance Requirements
One of the most notable updates in the National Frequency Plan is the transition from recommendations to enforceable rules. Previously, several requirements were optional; however, they are now mandatory obligations.
Moreover, equipment must now be designed with interference prevention in mind. Devices are required to consider adjacent band characteristics to minimize unwanted emissions. In contrast to the 2021 version, this is no longer advisory.
Additionally, spectrum efficiency is no longer optional. Devices must implement signal processing techniques that optimize spectrum usage. Consequently, this ensures more effective utilization of limited frequency resources.
Furthermore, a critical change involves frequency tolerances. Receivers are now required to strictly match the tolerances of transmitters within the same service. Therefore, this reinforces system consistency and reduces operational discrepancies.
Explicit Classification of Mobile Technologies
The updated plan formally defines mobile technology generations. Specifically, 3G is assigned to IMT-2000 systems, while 4G corresponds to IMT-Advanced systems.
Meanwhile, 5G is linked to IMT-2020 systems, supporting enhanced broadband, low-latency communication, and massive connectivity. Looking ahead, 6G is introduced under the IMT-2030 framework.
Overall, this clear classification improves regulatory clarity and aligns national frameworks with global standards.
Spectrum Allocation Updates
A significant regulatory development is the exclusive designation of the 3300–3700 MHz band for IMT systems. As a result, this restriction prevents the use of this band for non-mobile services.
Previously, other technologies could coexist in this range; however, the updated plan now limits its use strictly to advanced mobile services.
In addition, under Note 5.293, the 470–512 MHz band is now allocated on a primary basis to fixed and mobile services in Argentina and Ecuador. This change, implemented following WRC-23 outcomes, directly impacts how spectrum is accessed and utilized.
Why This Matters
These updates represent a fundamental evolution in regulatory expectations. On one hand, clearer rules improve predictability. On the other hand, stricter obligations increase the compliance burden for manufacturers and operators.
Therefore, organizations must adopt more rigorous design and planning processes. To support this, expert guidance can help navigate these evolving requirements effectively.
