Telephone - Cell Phones

History 1911 � American Telephone and Telegraph (AT & T) acquire the Western Union Telegraph Company in a hostile takeover. They purchased stocks in the company covertly and the two eventually merged.

In this article we're going to discuss what is arguably the greatest invention since the first telephone was made over 100 years ago, the cell phone.

The telephone was certainly a great invention. No question about it. We could make calls to our friends to invite them over for dinner, our boss to tell him we'd be out sick and our spouses to tell them we'd be home late for dinner. But once we were out of reach of a phone, our communication with the outside world came to a complete stop. If we had to make an emergency call while out on the road we had to either find a pay phone or some business kind enough to let us use theirs, which wasn't likely.

History 1946 � Worlds first commercial mobile phone service put into operation. It could link moving vehicles to a telephone network via radio waves.

Today, that has all changed with the invention of the cell phone. Actually, the concept of the cell phone began in 1947 when researchers looked at crude mobile car phones and realized that if they used small cells they could increase the traffic range of mobile phones. Unfortunately, the technology needed to do this did not exist yet.

History 1900 � First coin operated telephone installed in Hartford, Connecticut.

It wasn't until 1973 when a man by the name of Dr. Martin Cooper, a former GM for Motorola, made the first call on a portable cell phone in April of that year. He made the call to a rival of his, Joel Engel, who was Bell Labs head of research. Ironically, though, it was Motorola that were first to incorporate to the technology into a portable device, the first one to be designed to be used outside of the car.

History 1874 � Principal of the telephone was uncovered.

In 1977 AT&T and Bell Labs constructed their first cellular system. A year later were the first public trials of this new system with over 2000 trial customers. Two years later, in 1979, the first cellular system was put into use in Tokyo.

It wasn't until 1982 that the FCC finally authorized commercial use of cell phones in the United States. One year later the first cellular phone service was established in the United States called the Advanced Mobile Phone Service (AMPS). It was made available in Chicago by a company called Ameritech.

History 1876 � Alexander Graham Bell invents the telephone, beating Elisha Gray by a matter of hours.

In spite of the incredible demand for cell phones, it took cell phone service 37 years to become available in the United States. But by the year 1987 there were over one million cell phone subscribers and the airwaves were already overcrowded. Because of this, improvements needed to be made, which included increasing frequencies allocation, splitting of existing cells and improving the technology.

Today, we have probably the most sophisticated cell system that anyone could ever want, including cell phones that even take photos. But this hasn't come without many prices to the consumer and the general public around them.

History 1877 � The very first permanent outdoor telephone wire was completed. It stretched a distance of just three miles.

Aside from the high cost of cell service, especially if you go over the minutes allocated to you, there are the increased hazards and annoyances that these phones cause to others, such as going off in the middle of the big finale at a Broadway play or the danger of people using these phones in places like hospitals where the operation of sophisticated equipment can be affected.

Yes, we have our cell phones and all the wonders and headaches that go with them. Like they say, you don't get nothing for nothing.
