Colombia 900 MHz Update Enables Flexible Use
Colombia has officially redefined the regulatory framework for the Colombia 900 MHz band. Through Resolution 000024 of January 23, 2026, the National Spectrum Agency (ANE) modified several provisions of Resolution 105 of 2020 and updated the National Frequency Allocation Table (CNABF), introducing a more flexible approach to spectrum use.
This Regulatory Update marks a significant policy shift. Previously reserved exclusively for International Mobile Telecommunications (IMT), the 900 MHz band will no longer be limited to that designation.
Key Changes Under Resolution 000024 of 2026
According to Resolution 000024 of 2026 , ANE modified Articles 1.2.10, 1.7.1, 1.7.2, and national note CLM 21 of Resolution 105 of 2020.
Removal of IMT Exclusivity
Previously, the 900 MHz band was established and reserved for IMT operation. However, the update removes this exclusive reservation. While IMT technologies remain permitted, the band is no longer prioritized solely for nationwide commercial mobile operator deployment.
Moreover, ANE clarified that identification of IMT bands under ITU Radio Regulations does not prevent alternative uses where national administrations determine otherwise.
New Band Plan and Technical Conditions
The updated band plan applies to:
-
896–915 MHz (uplink)
-
941–960 MHz (downlink)
The allocation supports mobile and fixed radiocommunication services under an FDD configuration. Permitted channel bandwidths are 1.4, 3, 5, 10, and 15 MHz.
Additionally, the Resolution establishes interference mitigation obligations. If harmful interference arises from systems operating in the adjacent 850 MHz band, the 900 MHz assignee must implement necessary protection measures .
CNABF Update (902–928 MHz)
ANE also updated the CNABF in the 902–928 MHz range. The modification aligns national allocations with ITU Region 2 provisions and removes the IMT reference in the 902–905 MHz segment, adjusting national note CLM 21 accordingly .
Licensing and Spectrum Management Implications
Although flexibility has increased, this is not an unlicensed allocation. The 896–915 MHz and 941–960 MHz segments remain licensed spectrum, requiring a permit from the Ministry of ICT (MinTIC).
Therefore, the Colombia 900 MHz update represents a spectrum management reorganization rather than deregulation. Equipment operating in these bands will be treated as licensed mobile or fixed service infrastructure.
Furthermore, Resolution 105/2020 was updated to reflect these changes, including the removal of IMT exclusivity and the revised national frequency table .
Policy Objective: Connectivity and Efficiency
The Resolution emphasizes efficient spectrum use and expanded coverage, particularly in underserved areas. By enabling flexible use instead of exclusive IMT reservation, ANE seeks to support diverse radiocommunication applications aligned with national connectivity goals.
This approach prioritizes optimized spectrum management while maintaining regulatory oversight and licensing controls.
