Today, for modern man, the Internet is a very common element of life. It is worth noting that during the Titanic people became acquainted with the possibility of rapid communication only in the ocean. On May 7, 1895, Oleksandr Stepanovych Popov demonstrated a device he called a “lightning detector” designed to record the radio waves produced by the storm front. In 1896, Italian Guglielmo Marconi applied for a patent “for improvements in wireless telegraphy” in Great Britain. The device presented by Marconi repeated Popov’s design, which was repeatedly described in European popular science magazines at the time.

Lighthouses and ships became the first recipients of the telegraph. The luxurious Titanic was equipped with a state-of-the-art wireless telegraph under Marconi’s direct control.

The device can transmit messages 300 miles (555 km) during the day and 1,000 miles (1852 km) at night due to the refraction of long-wave radiation in the ionosphere. The telegraph’s range allowed passengers to send messages ashore in the form of a speech stream that later became deadly.

At around 23:40 on April 10, 1912, the Titanic collided with an iceberg that damaged the ship’s hull, causing the ship to collapse. Ten miles (19 km) from the sinking ship was the steamer SS Californian and could help the Titanic’s passengers, but the ship’s captain ignored the situation.

In 1912 there was no separate frequency for emergencies. Passengers and crew mixed the communication channels with random conversations, using the same radio waves for communication. The captains of some ships turned off the receivers due to the annoying noise from the Titanic’s electronics. Other ships, including the SS Californian, were instructed to remain autonomous without interfering with the Titanic’s message. The closest SS Californian did not hear the distress signal due to an order not to interfere with the sinking ship’s radio.

CQD (Come Quickly, Danger ) He reached the RMS Carpathia 90 miles (167 km) from the crash site. The Titanic was completely sunk when the ship arrived, but the Carpathia crew managed to save the lives of more than 700 people sailing in lifeboats.

The tragedy of the Titanic led to a rapid increase in the safety of radio equipment in the months after the accident. The United States and the United Kingdom have introduced 24-hour radio communications on every first-class ship. Operators should also use the same wavelength to transmit signals and periodically maintain radio silence to listen for potential distress signals.

The International Telecommunication Union (ITU) has allocated a separate 600 meter frequency band for ships only. Special technical measures have been taken to reduce interference from appliances and electronic devices.

The crash of the Titanic is one of the most famous tragedies in the world. On April 10, 1912, five days after her voyage from Southampton to New York began, the British ship collided with an iceberg and sank. More than 1,500 people died in the icy waters of the Atlantic Ocean, 700 passengers survived thanks to new technologies.
