So, I’m writing a sci-fi story, which has a setting which involves human colonists crash landing on a massive, icy hellhole. The weather is extreme on the surface, and because of it, wireless communication is useless, so for settlements to connect with each other, they need to physically move messages to other settlements, or use wired communication.
This is meant to give everything an air of mystery and desperation. The humans had been able to survive for hundreds of years, stranded without the ability to call for help. This brings them back to the medieval age, practically.
So, what I’m asking essentially, is there any way that a planet’s climate could block all/most wireless signals? Without that, the worldbuilding of the story pretty much falls apart.
