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.
