Colombia 900 MHz Spectrum Reform: Legal Engineering Analysis of Resolution 24 of 2026

Colombia has introduced significant changes to its spectrum management framework through Resolution 24 of 2026, issued by the National Spectrum Agency (ANE). The reform updates the National Frequency Band Allocation Table (CNABF) and establishes a more flexible regulatory approach to the Colombia 900 MHz spectrum, aiming to reduce access barriers and expand connectivity in rural and underserved regions.

Colombia 900 MHz Spectrum Update Under Resolution 24 of 2026

Resolution 24 of 2026 modernizes the allocation conditions applicable to the Colombia 900 MHz spectrum by introducing greater flexibility in its permitted use. Historically associated with legacy mobile services and more rigid technical conditions, the 900 MHz band now benefits from a framework that promotes technological neutrality and adaptive deployment models.

This regulatory adjustment enables operators to optimize the band’s technical characteristics while aligning with evolving market demands and network modernization strategies.

Strategic Importance of the 900 MHz Band in Colombia

Low-frequency spectrum such as 900 MHz provides strong propagation capabilities, including wider geographic coverage and improved signal penetration. These characteristics make the Colombia 900 MHz spectrum particularly suitable for:

• Rural and remote connectivity expansion

• Coverage in geographically complex terrain

• Cost-efficient infrastructure deployment

• Strengthening network reach in low-density areas

  
  

By enhancing flexibility in this band, ANE seeks to maximize its socioeconomic impact and improve national connectivity outcomes.

Regulatory Objectives and Market Implications

The reform reflects Colombia’s broader digital inclusion strategy. By lowering regulatory and structural barriers to spectrum use, Resolution 24 of 2026 encourages investment, promotes efficient spectrum utilization, and supports competition among service providers.

For telecommunications operators, the updated Colombia 900 MHz spectrum framework presents both compliance considerations and strategic opportunities. Companies should evaluate:

• Existing spectrum holdings and refarming possibilities

• Deployment models aligned with technological neutrality

• Long-term infrastructure planning

• Regulatory risk and licensing implications

  
  

Legal Engineering Perspective

From a legal engineering standpoint, the CNABF update reinforces the importance of aligning regulatory strategy with technical planning. Spectrum governance is increasingly dynamic, requiring operators to integrate compliance analysis into network design and investment decisions.

The Colombia 900 MHz spectrum reform demonstrates a regulatory shift toward flexible spectrum management aimed at fostering innovation, expanding rural coverage, and enhancing market efficiency.

As Colombia advances its connectivity agenda, Resolution 24 of 2026 positions the 900 MHz band as a strategic asset for sustainable telecommunications growth.
