Artificial and Natural Radio wave interference

Click For Summary
SUMMARY

The discussion centers on the interference between natural radio waves emitted by the sun and artificial radio communication devices. It establishes that natural radio noise spans all radio frequencies, necessitating that communication signals be significantly stronger to overcome this background noise. The analogy of conversing in a noisy bar effectively illustrates the challenge of transmitting information amidst natural radio interference. The conversation highlights the importance of signal strength in effective communication.

Hi everyone, I'm a beginer in communication science. I have very fundamental question.

We know that natural radio waves are emmited from sun to Earth (as a part of their electromagnetic spectrum); what will happpen if our communication devices uses radio waves of same frequency and wavelength matching this? Can information be passed between devices in this case?

And currently are we using frequency ranges (for communication devices) out of this natural radio waves frequency range? Pls help me in understanding this.

It is a question of signal strength. It is fair to say that natural radio noise covers all radio frequencies. Therefore, the only way we can ever communicate by radio is to make signals so strong that they overwhelm the noise.

Think of the analogy of sound. You can conduct a conversation in a noisy bar despite the background noise.
