Which risk abruptly increases when a communications satellite signal's frequency drifts outside the allocated band?

💡 Explanation

Adjacent channel interference emerges because frequency drift causes signal energy to spill into neighboring frequency bands using other signals, violating regulations via spectral leakage rather than encryption problems or antenna control, therefore signal integrity decreases.
