radio blackout
Communication dead zone
A radio blackout is a period when radio communication becomes impossible or severely degraded.
Solar flares can cause radio blackouts by disrupting Earth's ionosphere.
Military operations may impose deliberate radio blackouts to prevent detection: Maintain radio blackout until we reach the target.
Spacecraft experience blackouts during atmospheric reentry when plasma blocks signals.
