Real World Example

Imagine trying to shout across a busy street to get your friend's attention without losing your voice or being misunderstood. This is similar to how a satellite sends signals back to Earth, ensuring the message is clear despite the vast distance and potential interference. In this analogy, the busy street represents the space between the satellite and the Earth, your voice is the satellite’s signal, and your friend is the Earth station, demonstrating the challenge and importance of accurately transmitting information across long distances.
