Why Terrestrial Trunked Radio (TETRA) Still Matters
The global communications landscape continues to undergo significant transformation, driven by the universal rollout of 5G networks, gigabit broadband, LEO satellite constellations and continuous advancements in RF technologies. These changes are fundamentally reshaping how wireless networks and devices are designed and built, especially in consumer and enterprise sectors where ultrafast uplink and downlink speeds are taken for granted.
In parallel, critical communications infrastructure, spanning public safety, utilities, transportation, and defence sectors, remains heavily reliant on PMR systems such as Terrestrial Trunked Radio (TETRA) in Europe and the Middle East, and APCO P25 in the USA. Countries in the Far East use a mixture of technologies, including TETRA, PDT (China) and RCR STD-39 (one of many standards used in Japan). Despite rapid progress in wireless technologies, TETRA’s proven reliability and resilience mean it continues to be the preferred technology for safety-critical operations.
