Cell phones or cell phones are now one of the main needs for many people. An electronic that has a small form is useful as a means of verbal communication. However, for now cell phones or cell phones have many innovations that have dual features besides communicating like a smartphone.
Yes, it was Marty Cooper who played the role of the inventor of the cell phone, which deserves to be dubbed the father of the cell phone. Before the existence of mobile phones, initially cellphones could only be used in cars, you know because they needed a battery capacity like a car battery.
The following is an explanation of the inventor of the cellular phone that we can use as inspiration for all of us.
1. The life story of Marty Cooper
Martin “Marty” Cooper was born December 26, 1928 in Chicago, United States, the American engineer who led the team that in 1972-1973 built the first cell phone and made the first cell phone calls.
Cooper graduated from the Illinois Institute of Technology (IIT) in Chicago with a bachelor’s degree in Electrical Engineering in 1950. He joined the US Navy and served during the Korean War. After the war, he joined the Teletype Corporation, and in 1954 he began working at Motorola. He obtained a master’s degree in electrical engineering from IIT in 1957.
At Motorola, Cooper worked on many projects involving wireless communications, such as the first radio-controlled traffic light system, which he patented in 1960, and the first handheld police radio, introduced in 1967. He later served as vice president and director of invention and development in 1978-1983 for company.
2. The history of the invention of the cell phone
Cell phones were introduced by the American Telephone & Telegraph Company (AT&T) in 1946. However, in certain areas only 11 or 12 channels were available, so users often had to wait to use the system. Another drawback of the first phones was that the large amount of power needed to run them could only be supplied by the car’s battery. So, no cell phone is truly portable but only a car phone.
In 1947 AT&T Bell Laboratories, engineers Rae Young and Douglas Ring demonstrated that more cell phone users could be added by breaking a large area into many smaller cells, but that it required much more frequency coverage than was available at the time. According To Motherboard Know to meet the inventor of the first cell phone
However, in 1968 the US Federal Communications Commission asked AT&T for plans to employ a small portion of the UHF (ultra-high frequency) television band. AT&T is proposing a cellular architecture to extend its mobile phone service.
Motorola didn’t want AT&T to have a monopoly on cell phones and feared the end of its cellular business. Cooper is assigned to an urgent project to develop a cell phone. He thought that cell phones should not be chained to cars but should be portable. The result, the GynaTAC Phone (Dynamic Adaptive Total Area Coverage), is 23 cm tall and weighs 1.1 kg. That allows 35 minutes of talk before the battery runs out.
On April 3, 1973, Cooper introduced the DynaTAC telephone at a press conference in New York City. To make sure it worked before the press conference, he placed the first public cell phone call, to recruit Joel Engel, head of rival project AT&T, and happily said he was calling from a portable cell phone.
3. The first mobile phone was founded by Marty Cooper
In 1983, after years of further development, Motorola introduced the first portable mobile phone to consumers, the DynaTAC 8000x. Despite having a high price, this phone is a success.
4. Marty Cooper’s sequel
In the same year 1983, Cooper left Motorola and founded Cellular Business Systems, Inc. (CBSI), which is a leading company in mobile phone service billing. In 1986 he and his partners sold CBSI to Cincinnati Bell for $23 million, and he and his wife, Arlene Harris, founded Dyna, LLC.
Dyna served as the central organization from which they launched other companies, such as ArrayComm (1996), which developed software for wireless systems, and GreatCall (2006), which provided wireless service for Jitterbug, a mobile phone with simple features meant for the elderly. Cooper received the Charles Stark Draper Prize from the National Academy of Engineering in 2013.
That’s a little story about Marty Cooper in Hindi, the inventor of the cell phone. Wow, I have to thank you very much, here we are with Mr. Cooper!
