Signal propagation

Signal propagation refers to the way signals, such as radio, TV, or internet data, travel from one point to another. These signals are typically waves that move through the air, space, or over cables. Their speed and strength can change depending on the environment, obstacles, and distance. For example, radio waves travel through the air and can be affected by buildings or weather. The goal is to transmit the signal efficiently so it reaches its destination clearly and reliably, whether it’s a cellphone call or a Wi-Fi connection.
