TETRA solutions

When a fault in the system are unacceptable!


TETRA is the first open standard for professional digital radio (Professional Mobile Radio - PMR), which is supported by many established global manufacturers of infrastructure and subscriber equipment operating under this standard. The standard was created as a single pan-European digital standard for professional radio, so until April 1997 TETRA is the acronym meant "trans-European trunked radio" (Trans-European Trunked Radio). Due to the great interest shown in the TETRA in other regions of the world TETRA abbreviation begins to decipher as "Terrestrial trunked radio" (Terrestrial Trunked Radio).

In 2004 the specifications of the system interface between the ISI (Inter-System Interface) were approved. In 2005 is established the standard for high-speed data transmission known as TEDS (TETRA Enhanced Data Service), which provides data transmission in TETRA networks at speeds up to 115/230 kbps. Currently development of the standards is contineuing.

Motorola Solutions is one of the first participants in TETRA Consortium and participates actively in the development and improvement of the package TETRA standards. Motorola Solutions is one of the largest manufacturers of TETRA infrastructure and subscriber equipment.







Dimetra IP Micro provides business critical trunked voice and short data services including full duplex telephony calls. The solution is simple to deploy, operate, and maintain. It employs a Web-based Network Management GUI. The sites are linked through an Ethernet interface, potentially saving the cost of leased lines. Remote access allows system monitoring and diagnostics, this reduces maintenance cost. Interface to existing systems allows smoother migration for customers with analogue systems looking for advanced digital solutions. It is designed to reach a wide range of industrial, commercial and corporate customers - industrial enterprises, hotels, campuses, in construction, manufacturing, miningindustries and etc.

Dimetra IP Compact is based on an enhanced IP architecture. This allows optimum call setup performance and ensures high system availability. The IP architecture also gives you the inherent benefits of IP networking – these include economical network operation and system modularity to help minimise capital outlays. An added benefit is the option to carry IP traffic from network sites, over E1 or Ethernet  allowing you to take advantage of the lowest cost transmission technologies. To maximise operational efficiency, the system design leverages the latest virtualisation technology and world class IT server hardware. Dimetra IP Compact supports a number of capabilities that help you maximise system availability.
