Cellular Phones
Believe it or not, cell phones have a longer history then the radio. Cell phones started off in the 1920's and radios were first used in 1921. Some of the cell phone features were used in radios way back in the 1940s. Police used these radios.
In 1947 the idea of the cellular phone was developed as a mobile car phone. The concept of the cellular phone was produced by Bell Laboratories (also known as AT&T Bell) they introduced the cells for mobile phone stations. A device that converts light energy into electrical energy was developed by Russell Ohl. When trying to eavesdrop on the conversation there was a buzzing hornet sound and because of this the prototype was called Green Hornet. A long history of Motorola making automotive radio as two-way radios for taxicabs and police is amazing. In 1973 the actual cell phone was invented by Martin Cooper and other assisting inventors of Motorola. The "radio telephone system" is what it was called
In April 3, 1973, Cooper was the first person to make a call on a portable cell phone on to the amazement of the people walking on a New York City street. That first call was made on the first Motorola DynaTAC prototype to the head of research, Joel Engel, of the AT&T Bell Lab. This caused the technology and communications market to shift away from the place and toward the person. Cooper's vision for personal wireless communications was born.
In 1978, Bell Labs introduced the first commercial cellular network in Chicago using AMPS (Advanced Mobile Phone System). This was an analog mobile phone system. It became the primary analog mobile phone system in North America and is still widely available today, although it's used much less since the introduction of various digital standards.
The public was introduces to the large and expensive cellphone in 1984 when it made its presence. Towers war built by the cooperation of AT&T and the FCC. Something know as a "cell" or an area was created by the towers and covered a few miles. What was great was that the towers were able to transfer calls from each other.
Today worldwide the GPS cell phone is being known.
