INFORMATION ABOUT CELL PHONE
Cell Phones rule the world Now
Cell Phones are everywhere and their use is growing. Exactly what is a cell phone and why the name "cell"? Basically a cell phone is a radio telephone, but why didn't we have them years ago? The answer lies in the rapid rise of digital computers and very small and powerful microprocessors. One of the most important advantages of microprocessors is their ability to do very complicated operations with high reliability. Because of this cell phones are possible today. Just a few years ago they were impossible.
Who Invented the Cellphone
The cell phone was invented by Bell Labs from about 1947 to 1967, but a controversy has arisen about this. See the discussion in the next two paragraphs. Also see the the About.Com artilce Selling the Cell Phone - History of Cellular Phones.
According to an Associated Press Article in the April 12th issue of the San Francisco Chronicle, page D3 and an April 3, 2003 Chronicle Article, the Cell Phone was invented by Martin Cooper who at that time was a vice-president at Motorola. Both articles state that he made the first cell-phone call in 1973 on a street corner in New York using a base station at the top of a tall building in that city. He called an acquaintance at AT&T who at that time was a rival and perhaps said something like "we've done it". Motorola introduced its cell phone in 1983 after five generations, 15 years, and $ 90 million; but as mentioned above, the first commercial cell phone service was started by NTT in Japan on December 3, 1979.
This by no means the whole story, however. Cooper himself in the 10th paragraph of the April-3rd Chronical article states that "Bell Labs had invented this thing called cellular technology". What Martin Cooper apparently did was build a relatively small radio telephone which could be carried by a person. He did not develop the idea and the mechanism for automatically switching over when a phone went from one cell to another. The true inventor of the cell phone is the person or group who developed the concept of small cells and implemented the automatic switchover system, and this was Bell Labs. See the In-Box posting in Phone+ Magazine Give Bell Labs Its Due. Necessity is the mother of invention. If, as explained in the About.Com article, the FCC had not limited the number of channels available for radio telephones to 23, Bell Labs would not have been under intense pressure to develop the cellular concept.
