![]() ![]() While many of the switchboards were owned by private companies - initially Bell and then eventually companies like AT&T - state governments oversaw the resource to ensure it reached all citizens effectively. But, in the dawn of telephone communications, counties and cities directed calls via an operator through a manually operated telephone switchboard. Mobile phone operators have two-digit growth rates every day and mobile phone is becoming a tool almost more useful than normal telephones.With a smartphone in hand, it’s easy to forget where telecommunications started. Thinkers also defend, slowly but surely, that being continuously reachable does not have only disadvantages anymore. In Turkey, mobile phone is a part of daily life and the user number of networks increase day by day. Germany is 14th, behind Portugal and Greece. ![]() Over 60 percent of the population in Finland uses mobile phones. Because the real giant of mobile communication is the Finnish. Even though Europe is the center of big advancements, you would be mistaken if you think Germany is a mobile communication country. Not only that, there are one mobile phone in each home, actually one per person, and many people conduct their telephone calls over such digital networks. Though the telephones were used as even as telephones, even for a short time, today there is a phone in almost each house today. ![]() Since Bell, many changes have happened in the world of telephone. And the transmission was made in 10th of March in 1876 not by Sherlock Holmes, but by Alexander Graham Bell, the inventor of telephone. These words were the ones in the first telephone communication. Watson, can you come here? I need your help. In ten years, it was spread in America, and then in the whole world. Bell, armed with his profound knowledge regarding human ear amplifying vibrations, realized that it was possible to transmit human voice through wire. Even if other inventors had heard this faint sound, it was evident that they could not grasp the big difference. During his experiments, he heard the sound vibrations reflected from the wire he drew from one room to the other. And he was also trying to advance telegraph and make money out of it. ![]() Bell had dedicated all his life for the education of the deaf. But Bell managed to achieve this all by himself. In 1870s, many people were working to advance the telegraph. Before telegraph, which was viewed as a new method for its time, emergency messages had to be transmitted using horse messengers, smoke signs, pigeons and ships. But in telegraph use, there was no possibility of transmitting human voice over wires. Before Bell's invention, the fastest way to convey a message was to transmit it through telegraph lines via Morse alphabet. When Alexander Graham Bell invented the telephone in 1876, a new era was opened in human communication. Telephone networks were first installed in urban areas and then transformed into inter-city, international installments and entire world was connected in communication via satellites. The main principle in telephone's operation is the sound waves coming out f the mouth being turned into electrical signals first, and then being transmitted away by various sending methods, and then transforming the electrical signals back to sound waves that can be heard by ear. Telephone is an electrical voice exchange device that enables information exchange between people and systems in distant locations. ![]()
