Telecommunications engineering, or telecoms engineering, is an engineering discipline that brings together all electrical engineering disciplines including computer engineering with systems engineering to enhance telecommunication systems. The work ranges from basic circuit design to strategic mass developments. A telecommunication engineer is responsible for designing and overseeing the installation of telecommunications equipment and facilities, such as complex electronic switching systems, copper wire telephone facilities,fiber optics cabling,IP data systems,Terrestrial radio link systems for conventional communications and process information. Telecommunication engineering also overlaps heavily with broadcast engineering.

Telecommunication is a diverse field of engineering which is connected to electronics, civil, structural, and electrical engineering. Ultimately, telecom engineers are responsible for providing the method for customers to have telephone and high-speed data services. It helps people who are closely working in political and social fields, as well accounting and project management.
