👉 Telephone engineering, also known as telecommunications engineering, involves the design, development, and maintenance of systems that enable voice communication over various media. It encompasses the creation of hardware (like switches, routers, and transceivers) and software (such as protocols and network management systems) that facilitate the transmission and reception of voice signals. This field deals with the physical layer, which manages the electrical and mechanical aspects of signal transmission, and the data link layer, which handles error detection and correction. Telephone engineers also focus on network architecture, ensuring efficient routing and bandwidth allocation, and implementing security measures to protect against eavesdropping and interference. They work on improving voice quality, reducing latency, and integrating advanced technologies like VoIP (Voice over Internet Protocol) and 5G networks to meet the growing demands of modern communication.
