The first car phone service was
launched in 1949. The Mobile Telephone Service (MTS) was called. Italian
physicist Guglielmo Marconi, wireless communications sent by wireless signals a
successful and a half miles, but the beginning, when in 1895, began several
years ago.
In 1896 Marconi wireless telegraph system in the world for the first patent was awarded. The Wireless Telegraph and Signal Company formed in 1897. In the same year successfully sent wireless signals a distance of twelve miles.
Curvature of the Earth in 1901, Marconi succeeded in sending wireless signals proved that is affected. St. John's, Newfoundland, a distance of two miles, Cornwall, England, and he proved that transmit the signal.
Other scientists and researchers with Marconi, wireless transmission continued to do research. 1932 Caster Gandolfo and the Vatican City the world's first microwave radiotelephone link, a small Italian town founded by the Pope's summer residence at a distance of about thirty miles.
America's 400 miles to beach the ship in 1922, held talks on the radio - be the first ship. Inter-continental United States and England in the 1930s in the midst of telephone contact.
As technology advances, interest on a car phone service was established. The first car is a mobile phone service was introduced in 1949, but was large and heavy equipment. Phone is a great receiver (a large piece of luggage on the scale) is required. The vehicle was placed in the trunk. Talking on the phone to have a button away. Ask the other person, the button must be released. Using a two-way radio was more like. It's not about a person can listen at the same time. Technology came later.
Direct phone calls the first mobile phone service is not known. Instead of mobile phone operator in a service call. Telephone company operator to operator, which call attached to the collar. Technology has progressed through the beginning of 1960, but was only slightly. Step out of line in operation. The first mobile phone to connect to a telephone call to save the operator was able to connect directly to telephone company. "Mobile telephone service reform" better service or to be invited to IMTS.
The early part of 1980 full-duplex capable phone. This is a person who does not speak and listen at the same time could mean. However, there were still heavy caller and the receiver.
Today's technology continues to improve and upgrade will continue. Cell phones are very popular. Today he is a true mobile device and are easy to transport. Cell phone only weighs a few ounces today. Some cell phones are very small as a little button, but can be difficult to use.
Cellular technology continues to improve. In the United States, carriers move to digital technology with analog technology. Even calls to digital and more secure network, but is still far from completely secure.
Today, some people dropped calls, and networks, which are to be welcomed in some areas through the extension of the experience.
