TETRA short for Terrestrial Trunked Radio, is a digital communication standard designed to offer secure, efficient, and versatile two-way radio communication. Although originally conceived in the early 1990s for the European Public Safety Sectors in the framework of the Schengen agreement, TETRA has subsequently been developed to fulfill the operational requirements of a variety of end users. Today it is considered as THE technology of reference WORLDWIDE across all mission and business critical market sectors including Public Safety and Security, Transport, Utilities, Extraction and Mining, Critical National Infrastructure protection and the Military.
- Global OPEN Standard
- High Availabilty
- Highly reliable and secure network
- Excellent coverage
- Less power consumption
TETRA utilizes time-division multiple access (TDMA) with four user channels on a single radio carrier, with 25 kHz spacing between carriers. TETRA supports both point-to-point and point-to-multipoint communication and includes provisions for digital data transmission at relatively low rates. TETRA Mobile Stations (MS) can operate in two modes: direct-mode operation (DMO) or trunked-mode operation (TMO) using switching and management infrastructure (SwMI), which consists of TETRA base stations (TBS). TETRA also facilitates various data communication types, including status messages, short data services (SDS), and packet-switched or circuit-switched data on dedicated channels. TETRA prioritizes security, featuring authentication for terminals and infrastructure, as well as encryption for air interface and end-to-end communication.
Enhancing security through advanced encryption and mutual verification to ensure robust and protected communication channels for utmost safety.
TETRA offers substantial capacity with four-time slots within a single carrier, making it highly efficient for handling multiple users simultaneously.
TETRA delivers exceptional communication quality, characterized by crystal-clear voice and highly reliable data transmission, making it ideal for mission-critical applications.
TETRA is VALUED for granting user organizations complete command over their radio communications, extensive user insights, and enduring product reliability and services.
