The Titanic was equipped with a Marconi Wireless system invented by Guglielmo Marconi. The system was of great use at the time because it didn't require you to stay in one place to send and receive messages. Communication could continue up to 400 miles during the day and 2,000 miles at night. Passengers thought that having this system was a great luxury, being able to send messages to family and friends while on a moving ship. It was the most powerful system in use at that time.

The Marconi Wireless system was powered by a five kilowatt motor generator located within Titanic's lighting system. The main transmitter was a rotary spark design. There was a four wire antenna suspended between Titanic's two huge masts. These wires are what transmitted the electronic impulses to the shore.

The wireless system on Titanic used Morse Code to relay their messages. There were two wireless operators, or telegraphists, that were employed by the Marconi Wireless company, who sent and received any and all messages aboard their ship. Harold Bride and Jack Phillips. They relayed all of the ice messages to the bridge on the fateful night Titanic sank.

The wireless system aboard Titanic was her only link to the shore. She was out on wide open sea with no telephone, no nothing. When she left Belfast, she received messages of good luck, and by the time she had passed Queenstown, she was already receiving ice warnings. But these messages weren't posted, and the officers only knew of one posting. This could be part of the reason Titanic foundered, due to the lack of all wireless operators on board Californian not being at their posts to receive Titanic's distress call-
