On June 18, 2025, Colombia’s Communications Regulation Commission (CRC) published Circular 162 of 2025, introducing the second update to the technical standards for the homologation of terminal equipment. This update responds to recent spectrum auctions and international trends, particularly the allocation of the 2,500 MHz and 3,500 MHz bands for IMT services, including 4G and 5G technologies.

The circular establishes detailed technical requirements for mobile terminal equipment, fixed telephones, and satellite phones regarding network connection and electromagnetic exposure. It specifies the applicable frequency bands, network connection standards (such as FCC, ETSI, and 3GPP), and radiation standards (IEEE Std.C95.1 or ICNIRP, in line with ITU-T K.52). The regulation aligns Colombia’s requirements with international best practices and ensures compatibility with newly assigned spectrum bands.

Circular 162 of 2025 repeals Circular 155 of 2024, consolidating all updated technical requirements into a single document. The update is mandatory for all stakeholders involved in the approval, importation, and commercialization of terminal equipment in Colombia. Non-compliant devices will not be eligible for homologation or legal sale in the country.

The measure aims to guarantee user safety, interoperability, and efficient spectrum use, while facilitating the deployment of next-generation mobile networks. The CRC’s action positions Colombia at the forefront of regulatory adaptation to technological advancements in telecommunications.

This update is classified as High Impact.

Key reasons for high impact:

• Mandatory update to technical standards for homologation of a broad range of terminal equipment (mobile, fixed, satellite).
• Introduction of new frequency bands (2,500 MHz and 3,500 MHz) for IMT services, including 4G and 5G.
• Alignment with international standards (FCC, ETSI, 3GPP, IEEE, ICNIRP) for network connection and electromagnetic exposure.
• Repeal of previous requirements (Circular 155 of 2024), making compliance with the new circular obligatory.

Who is affected?

Manufacturers, importers, certification bodies, telecom operators, and distributors of mobile, fixed, and satellite terminal equipment.

Conclusion:

All stakeholders must ensure that devices comply with the updated technical standards to obtain homologation and access the Colombian market. Immediate review and adaptation of compliance processes are required.
