A short story about mobile phones

A short story about mobile phones The concept phone was created at the end of 1940. Scientists have discovered that small cells, with a frequency re-use that could create something like a phone. Technology that existed at that time, however, meant that it was impossible. Bell is responsible for the design of mobile phones, but only for use in automobiles. The first inventor of a portable phone is that Dr. Martin Cooper made his first call in 1973. He made his call to his rival Bell, which is in close contact with him to win the race of the cell technology. In 1977, the phone has been created and given to more than 2,000 customers to test. Continue to test mobile phone in the end 1970 and early 1980. Mobile phones in 1982 were finally approved for public use in the United States. The phone has become a great demand among consumers and in 1987 the airways filled with cellular frequencies. Since the FCC has refused to allow the mobile industry has a greater bandwidth, mobile phone company started to expand and upgrade its technology. Today, mobile phones are found in virtually every home and many people could not imagine life without them. Now we have phones that include camera tricks, such as cellular phones, phones that download music, video and camera phones to text messages. The mobile telephony services have come along way since the idea was conceived in 1947, and we have Dr. Martin Cooper and thank Joel Engel.
