The Telecommunications Authority of Trinidad and Tobago (TATT) has published Version 4.0 of the Trinidad and Tobago Frequency Allocation Table (TTFAT), covering the range from 8.3 kHz to 3000 GHz and replacing Version 3.1 from February 2025.

This update incorporates the ITU Radio Regulations 2024 edition and WRC-23 outcomes for Region 2, defining spectrum allocations, permitted radiocommunication services, licensing conditions, and national footnotes for orderly spectrum use under Section 41 of the Telecommunications Act.

The plan optimizes spectrum management for modern telecommunications (5G, NTN, broadcasting), promoting efficiency, competition, and innovation, while impacting existing operational plans and licenses without introducing new product-level technical standards.

Why?

The TTFAT Version 4.0 fundamentally updates Trinidad and Tobago's national spectrum allocation framework across 8.3 kHz to 3000 GHz, incorporating ITU Radio Regulations 2024 and WRC-23 outcomes for Region 2. This has major implications for spectrum planning, licensing, national footnotes, and deployment strategies in the telecommunications sector. While no new device-level technical standards (safety, EMC, SAR, etc.) or certification requirements are introduced, the changes are structural, affecting operational compliance, interference management, and service rollouts for modern networks like 5G and NTN.

Who?

Mobile network operators (national/territorial) Fixed wireless and broadcasting providers Spectrum license applicants and holders Infrastructure vendors (base stations, satellite equipment) Regulatory compliance and spectrum planning teams Rural broadband and emergency service developers Industry associations and stakeholders

Conclusion

This is a high-impact strategic regulatory update for Trinidad and Tobago's telecom sector. It modernizes the spectrum framework, aligns with global standards, enables efficient use for emerging technologies, and supports competition—without immediate new product certification burdens.
