You could not see the cell phones totally fifty years ago. But now everything is different for us, with the advance technology in our wonderful world, nearly all of the people have the cell phones. Men, women, and even the small children and the old people can carry around the portable models of the telephone. The cell phones have the very interesting history, through it; you can get the whole pictures for how the portable wonder became what it is at the present.
A skilled, analytical chemist named Michael Farady began exhaustive research for finding a space that could conduct electricity in 1843. He told of his findings, and these advances of 19th century science and technology have had an incalculable effect on the development of the cell phones of these days.
By the year of 1865 a dentist Dr. Mahlon Loomis became what is thought to be the first person who was able to communicate wirelessly through the atmosphere. Between 1866 and 1873 it transmitted telegraphic messages 18 miles from the tops of the Cohocton to Beorse Deer Mountains in Virginia. Dr. Mahlon Loomis developed the method of transmitting and receiving messages by using Earth's atmosphere as a conductor. He also launched kites enclosed with copper screens that were linked to the ground with copper wires. He was awarded a $ 50,000 research grant from Congress to continue his studies.
Then, a former general manager from the systems division of Motorola, Dr. Martin Cooper, became who is thought to be the inventor of the first portable handset in the year of 1973. Dr. Cooper was also the first person to make the calling with the portable cell phones. In New York, he set up a base station using the first working prototype of the cell phones which is called the Motorola Dyna-Tac. He and Motorola took this advanced technology to New York to show the public.
Later on, the cell phones went to the public and the public testing began in 1977. Chicago was the home for the first trials with 2,000 people for it. After Chicago, there were later trials in Washington, D.C. and Baltimore, and then, in 1979, it fast spread to Japan.
In 1988, the regular technologies have been changed when the CTIA - Cellular Technology Industry Association - was formed to lay out the realistic goals for the cell phone providers. The research for the new applications of the development was included for us. In 1991, the Telecommunications Industry Association set a new standard using the creation of the TDMA Interim Standard 54.
Cell phones have had quite a long journey to be what today it is. Although there was a big need for cell phones, it took about 37 years for them to become commercially available in the United States. It is the surprise and a success for the people. Almost 50 years ago, wireless service was actually invented by the great men, so it is very difficult for us to believe that just over the past couple of decades, the cell phones have only become popular. There are more than 60 million people who are using the cell phones at the present.
