Morphology

wake-up + signal

The meaning is directly compositional: 'wake-up' (to cause something to stop sleeping or leave a low-power state) combined with 'signal' (an electronic transmission) yields 'a signal that wakes a device.' Although domain-specific and hyphenated, the sense follows regular English verb+noun compounding and is easily inferable by a B1 learner who knows the constituents.

Etymology

Wake-up signal in electronics comes from the same idea. A short radio or electric pulse tells a sleeping device to wake up, so the term means 'a signal that makes a device leave sleep and start working'.
