Which of the following statements about Link 11B is true?

Link 11B operates as a half-duplex system, which means that it can transmit data in one direction at a time, either sending or receiving but not both simultaneously. This feature is critical for understanding how data is managed in tactical communications environments where Link 11B is deployed. In a half-duplex setup, devices take turns communicating, which is often sufficient for many military operations where the timing of information exchange is crucial but doesn't require simultaneous bidirectional communication.

Furthermore, the other characteristics of Link 11B, such as its secure nature and operation type, are defined within different contexts and specifications. Recognizing the operational constraints of a half-duplex system helps in understanding how Link 11B integrates with other communication networks and how it affects the flow and timing of operational data.
