FWIW, the US communication systems are designed to work in insanely degraded EM environments, they push the bounds of information theory. Bandwidth won’t be great but they will work. The other side of this is that any system that can degrade the environment to that extent is painting a giant target on itself, and the US has purpose-built “seek and destroy” platforms for anything that is aggressively limiting available bandwidth. A lot of US systems are designed to be functional with bandwidth that is significantly less than an old dial-up modem. In the average case that doesn’t happen but it is an explicit design target to enable operation in severely compromised environments.
