My story takes place on a hot desert planet that is a colony. At some point people are out in a very hot and inhospitable area of the desert. Dust storms, high heat, constant wind, etc.
Characters have tech that allows them to access the planetary network via satellite. But I'd like them to be out there and get isolated without access - to be truly disconnected.
I assume that a heavy storm with blowing sand and lots of dust in the air would affect things, but what about on a normal day with no severe storm?
I had thought about having this part of the planet have some natural way to interfere. Possibly a magnetic field or something.
I'm not sure if that would work, looking for ideas.
