How are nets stacked in Link 16?

• A. Nets are stacked with the same time slots, just different hopping patterns
• B. Nets are stacked by alternating frequencies only
• C. Nets are stacked by time slots in different frames
• D. Nets do not share timing and operate independently

Answer: (A)

Nets in Link 16 are multiplexed in time using TDMA, so time is divided into frames and slots. To fit multiple nets into the same time slots, each net uses its own frequency-hopping pattern. This means several nets can occupy the same time slot, but they are kept separate by using different hopping sequences. The hopping pattern provides the spectral separation that prevents collisions and maintains jam resistance, while the shared time slot structure maximizes efficiency. So, nets are stacked in the same time slots, distinguished by their different hopping patterns. Using only alternate frequencies wouldn’t guarantee separation in time, and spreading nets across different frames or treating them as timing-unique would waste capacity and reduce efficiency.
