Martin "Marty" Cooper (born December 26, 1928) is an American engineer. He is a leader in the wireless communications industry, with eleven patents specifically in the radio spectrum management field. At Motorola in the 1970s, Cooper invented the first handheld cellular mobile phone in 1973 and led the team that developed it and brought it to market in 1983. Martin is considered "the father of the (handheld) cell phone" and is also cited as the first person in history to publicly call the handheld cellular phone. Cooper co-founder of several communications companies with his wife and business partner Arlene Harris; He is the co-founder and current president of Diana LLC in Del Mar, Calif. Cooper also sits on committees supporting the US Federal Communications Commission and the United States Department of Commerce. In 2010, Cooper was elected a member of the National Academy of Engineering for leadership in the manufacture and deployment of cellular portable handheld telephones.
Education
Martin was born in Chicago to Ukrainian Jewish immigrants. He graduated from the Illinois Institute of Technology (IIT) in 1950. After graduation he served as a submarine officer during the Korean War. In 1957, he joined IIT. Master's degree in Electrical Engineering from
Work and Career
At Motorola, Cooper worked on several projects involving wireless communications, such as the first radio-controlled traffic-light system he patented in 1960, and the first handheld police radio, introduced in 1967. He later served as the Vice President. and Director of Research and Development for the company (1978-83). Mobile telephones were introduced by the American Telephone and Telegraph Company (AT&T) in 1946. However, only 11 or 12 channels were available in a given area, so users often had to wait to use the system. Another weakness of the first mobile phones was that a large amount of power to run them could only be supplied from the car's battery. Thus, there were no truly portable phones but only car phones. In 1947, AT&T Bell Laboratories engineers W. Rae Young and Douglas H. Ring showed that breaking up a large area into several smaller cells could add more mobile users, but this required greater frequency coverage than was needed at the time. However, in 1968 the U.S. The Federal Communications Commission (FCC) asked AT&T for plans to employ a little-used portion of the UHF (ultrahigh frequency) television band. AT&T proposed a cellular architecture to expand its car-phone service. Motorola did not want AT&T to have a monopoly on cell phones and feared the loss of its mobile business. Cooper was put in charge of the immediate project to develop the cell phone. He thought that cell phones should not be chained to the car but should be portable. The result, the DynaTAC (Dynamic Adaptive Total Area Coverage) phone, was 23 cm (9 in) long and weighed 1.1 kg (2.5 lb). This allowed it to talk for 35 minutes before its battery drained. On April 3, 1973, Cooper presented the DynaTAC phone at a press conference in New York City. To make sure it worked ahead of the press conference, he made the first public cell phone call to AT&T's rival project chief Joel Engel, saying he was calling from a portable cellular phone. In 1983, after years of further development, Motorola introduced the first portable cell phone to consumers, the DynaTAC 8000x. Despite the $3,995 price tag, the phone was a success. That same year, Cooper left Motorola and joined Cellular Business Systems, Inc. (CBSI), which became a leader in billing of cellular phone services. In 1986 he and his partners sold CBSI to Cincinnati Bell for $23 million, and he and his wife, Arlene Harris, founded Diana, LLC. Diana served as a central organization from which she launched other companies, such as Airecom (1996), which developed software for wireless systems, and Greatcall (2006), which provided wireless service for Jitterbug. , a cell phone that meant simple features. Elderly. Cooper received the Charles Stark Draper Award from the National Academy of Engineering in 2013.
What is Martin Cooper's net worth?
Martin "Marty" Cooper is an American inventor who has a net worth of $600 million. Cooper will always be remembered as the man who invented the cellular phone. Known as the "father of the handheld cellular phone", he developed the first cellular portable handheld police radio system in 1967, and he conceived the first portable cellular phone for Motorola. On April 3, 1973, Martin became the first person to publicly make a cell phone call, and the recipient of that phone call was AT&T's Joel S. Engel was.
