Ironically, though, it was Motorola that were first to incorporate to the technology into a portable 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.

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.

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 d

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.

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.

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 cel
