Communications blackout
There are two related events which the term "
communications blackout" refers to. In
military science, such a blackout is the intentional decision of a
military unit not to use radios; this is done in an attempt to "hide" from the
enemy. In more general
telecommunications, the term has the following meanings, which can also apply to military units:
1. A cessation of communications or communications capability caused by a lack of power to a communications facility or equipment.
2. A total lack of communications capability caused by propagation anomalies, e.g., those present during strong auroral activity or during the re-entry of a spacecraft into the Earth's atmosphere.
