Industry 4.0


Teltronic develops its communications systems in line with open standards, offering maximum interoperability and all the guarantees of investing in a technology with future value.

TETRA (Terrestrial Trunked Radio) is a digital radio standard defined by the European Technological Standards Institute (ETSI). This is an open standard, created to meet the needs of critical communications in the Public Safety and Emergencies market. It is the global de facto standard for highly critical environments, with more than 4 million users worldwide.


The term 5G refers to the fifth generation of mobile networks and represents substantial improvements in terms of three main benchmarks: Greater bandwidth and data transmission speed, significantly reduced latency, and high capacity, which allows for a greater number of connected devices.  5G is one of the central elements of the “Industry 4.0” program, which is almost synonymous with the “Fourth Industrial Revolution”.


LTE (Long Term Evolution) is the mobile broadband communication standard known in the commercial sphere as 4G technology. It offers end-to-end digital IP communication, and its definition and standardization are the responsibility of the 3GPP (Third Generation Partnership Project).
