Propagation
Propagation refers to how radio signals travel through space and different environments. It's like understanding how radio waves move from one point to another, similar to how ripples spread across water. In telecommunications jobs, this knowledge is crucial for setting up wireless networks, mobile phone systems, and radio communications. When you see this term in resumes, it usually means the person knows how to plan and optimize wireless coverage, solve signal problems, and ensure good communication quality. Think of it as mapping out how well a cell phone signal or radio broadcast will work in different areas and conditions.
