teletekniikassa

Teletekniikka (telecommunication engineering) is a branch of electrical engineering focused on the design, implementation, and operation of systems that transmit information over distances. It covers both fixed and mobile communication networks, including voice, data, and video transmission, as well as broadcasting, satellite, and industrial communications. The field integrates aspects of electronics, signal processing, networking, and information technology to enable reliable connectivity.

Core topics include transmission media (fiber, copper, wireless spectrum), modulation and coding, RF design, digital signal processing, network architecture, and protocol design. It also encompasses network management, performance optimization, quality of service, security, reliability, and standardization work with bodies such as ITU, IEEE, and 3GPP. The practical focus is on designing and maintaining systems that can carry large volumes of data with low latency and high availability.

Applications span telecommunications operators, internet service providers, data centers, and industrial sectors such as transportation and energy. Professionals in teletekniikka may work in network planning and deployment, equipment design, system integration, testing, and cyber-physical security.

Education in teletekniikka is typically part of electrical engineering with specialization in communications or teletekniikka. Students gain knowledge of circuit theory, signals, programming, simulation tools, and project-based design. The field continues to evolve with trends such as 5G/6G, fiber access, software-defined networking, network function virtualization, and edge computing.
