It transmitted signals from Ballycastle, Northern Ireland, to Rathlin Island.

Marconi's name made headlines when he reportedly received the first transatlantic radio signal on Signal Hill in Newfoundland using an antenna supported by a kite.

This transmission was groundbreaking, as many believed that radio signals could only be transmitted in a straight line.

The Poldhu station in Cornwall used a powerful spark gap transmitter that delivered signals significantly more powerful than previous attempts.

The received message consisted of three dots denoting the letter "S".

Although some dispute the validity of this achievement, it has sparked a serious scientific debate about the propagation of radio waves.

The Marconi device reliably received messages at a distance of more than 2,500 kilometers at night and 1,100 kilometers during the day.

His company, Marconi, carried out regular transatlantic news broadcasts.

He built a station near Wellfleet, Massachusetts, which later conveyed the famous message of the President of the United States to the King of the United Kingdom.

His innovations laid the foundation for modern radio communications, despite the ongoing debate about the true origin of radio technology.

Conferences are among the most significant and large-scale professional events that attract a wide audience and cover a wide range of topics. These events last several days, providing participants with an opportunity to interact with a diverse group of professionals, scientists and industry leaders. Large conferences can attract thousands of participants, providing a platform for both knowledge sharing and networking.

A typical conference program includes various events designed to meet different interests. Key presentations by leading experts set the tone by providing food for thought, while panel discussions and presentations go deeper-into the study of specific topics.

To participate in the conference, speakers need to prepare in advance. For those who want to make a presentation, sending abstracts is an important step. This short document is usually up to 350 words in length. When accepted, the speakers prepare detailed materials and deliver a report that attracts and informs the audience. Such a preparation ensures high quality materials that benefit all participants.

Conferences are not only aimed at personal development; they also contribute to the growth of industries and academia. By participation in person or online, attends gain access to highly specialized knowledge and unique opportunities to broaden their professional's horizons.
