teletehnika

Teletehnika is a field of technology and engineering focused on the design, development, installation, and operation of systems for transmitting information over distance. It encompasses transmission media such as copper, fiber, and wireless, as well as core networks, access networks, and related equipment including switches, routers, base stations, antennas, and signal processing hardware and software.

The field evolved from the practices of telegraphy and telephony to the modern digital communication networks used today. Key milestones include the transition from analogue to digital transmission, advances in modulation and coding, and the deployment of broadband and mobile networks, along with satellite and broadcasting technologies. Teletehnika integrates principles from electrical engineering, computer science, and information theory.

Subfields include network engineering (planning, provisioning, and management of telecommunication networks), transmission technology (RF engineering, optical communications, microwave), digital signal processing, telecommunications systems and switching, network security, and the development and application of telecommunications standards and protocols.

Education in teletehnika typically leads to degrees in telecommunication engineering or teletehnika, with courses covering circuits, signal processing, communications theory, data networks, wireless technologies, optical networks, and field installation. Careers span equipment manufacturing, network operators, system integration, research, and technical services.

Current trends in teletehnika include extensive fiber-optic deployment, development of 5G and beyond, IP-based transport, software-defined networking and network virtualization, Internet of Things connectivity, and advances in satellite communications. The field prioritizes reliability, efficiency, and security in the global exchange of information.
