ORIGINS
Cell phones may be new devices, but they originated in the 1920’s. Radios were used since 1921. Features were put into these radios in the 1940’s, and they were used by police. The concept of the cellular phone was developed in 1947 which originated from the mobile car phone. The concept of the cellular phone was produced by Bell Laboratories.
The first actual cell phone was made in 1973 by Martin Cooper of Motorola and other assisting inventors who used the idea of the car phone and applied the technology necessary to make a portable cell phone possible. Cell phones were first made available to the public in 1984. Back then, they were very large, expensive instruments.
First Generation Cell Phones
While the technology had been developed, it was not until 1971 that AT&T submitted a request to the FCC for cellular service. It took more than 10 years for an approval and in 1982, the FCC allocated the frequencies of 824-894 MHZ Band to Advanced Mobile Phone Service (AMPS).
In 1983, Motorola unveiled the first truly portable cellular phone to the world. It was called the Motorola DynaTAC 8000X.. The DynaTAC800X was extremely lightweight for its time and only weighed about 28 ounces. It was 13 inches x 1.75 inches x 3.5 inches and was known as the Brick for its shape. It was largely developed with the help of Dr. Martin Cooper of Motorola.
Cell phones have evolved immensely since 1983, both in design and function.
From the models old until the iPhone 3G, which can take a picture, play a video, or run one of the thousands applications available from the Apple Store.
