When did the wireless operator Wake up?

The wireless operator "Wake Up" refers to a notable incident in radio communication history that occurred on April 15, 1912, when the RMS Titanic sank. The ship's wireless operators sent distress signals using the Marconi system, which played a crucial role in alerting nearby ships. The phrase "Wake up" was used to instruct other operators to pay attention to the urgent messages being transmitted. This incident highlighted the importance of wireless communication in emergency situations.
