Why Terrestrial Trunked Radio (TETRA) still matters - A CML Micro Whitepaper

16 June 2025

CML Micro’s latest whitepaper explores the importance of Terrestrial Trunked Radio (TETRA) in mission-critical communications. Despite the evolution of LTE/5G networks, TETRA remains vital due to its resilience, reliability, and secure voice-centric capabilities.

Key Topics Covered Include:

  • The Critical Communications Landscape Today: An overview of the current state of communications infrastructure and the slow transition from TETRA to mobile broadband systems.
  • Why TETRA Remains the Backbone: TETRA’s unmatched network coverage, rapid call setup, and robustness during emergencies continue to support public safety and utility operations worldwide.
  • Networking Advantages: Superior coverage and emergency call prioritisation make TETRA indispensable in high-risk scenarios.
  • Operational Integration: Deep integration across blue light services, transport, utilities, and defence, with significant investment making migration costly and complex.
  • The Shortcomings of TETRA: Limited data capability and ageing infrastructure pose challenges, especially with component availability.
  • Why CML Micro Supports TETRA: With decades of RF experience, CML Micro continues to invest in high-performance components to sustain and evolve TETRA systems.
  • New PA Products for Mission-Critical Communications: Introduction of CMX90A007 and CMX90A009 amplifiers designed for TETRA applications.
  • Real-World Testing and Validation: Lab results demonstrating improved adjacent channel performance and reduced noise.
