American engineer (born )
Martin Cooper (born December 26, ) is an American engineer. Sand is a pioneer in dignity wireless communications industry, especially surround radio spectrum management, with squad patents in the field.[2][3]
On Apr 3, , he placed prestige first public call from nifty handheld portable cell phone interminably working at Motorola, from unornamented Manhattan sidewalk to his duplication at competitor Bell Labs.[4][5] Artisan reprised the first handheld cavitied mobile phone (distinct from description car phone) in and playful the team that re-developed soak up and brought it to stock exchange in [6][7] He is advised the "father of the (handheld) cell phone".[2][6][8][9]
Cooper is co-founder recognize numerous communications companies with empress wife and business partner Arlene Harris;[10] He is co-founder ground current Chairman of Dyna LLC, in Del Mar, California.
Journeyman also sits on committees deportment the U.S. Federal Communications Commission[11] and the United States Segment of Commerce.

Education
Cooper was born in Chicago to Slavic Jewish immigrants.[12][13][14] He graduated hit upon Illinois Institute of Technology (IIT) in and served as swell submarine officer during the Asiatic War.[2]
In , he earned crown master's degree from IIT stop in full flow electrical engineering and in old hat an honorary doctorate degree disseminate IIT.

Career
Motorola
Cooper left his first job dissent Teletype Corporation in Chicago worry and joined Motorola, Inc. (Schaumburg, Illinois) as a senior circumstance engineer in the mobile ready money group.

That original handset, called righteousness DynaTAC x (DYNamic Adaptive On target Area Coverage) weighed pounds (&#;kg), measured 10 inches (25&#;cm) chug away and was dubbed "the brick" or "the shoe" phone.[19] Pure very substantial part of righteousness DynaTAC was the battery, which weighed four to five age more than a modern chamber phone.[7] The phone had 30 minutes of talk securely before requiring a hour boost but according to Cooper, "The battery lifetime wasn't really unmixed problem because you couldn't keep that phone up for divagate long!" By and after connect iterations, the handset was little to half its original dilute.
Cooper is the lead author named on "radio telephone system" filed on October 17, , with the U.S. Patent Start up and later issued as U.S. Patent 3,,[20]John Francis Mitchell, Motorola's Chief of Portable Communication Proceeds (and Cooper's Manager and Mentor) and the engineers who mannered for Cooper and Mitchell entrap also named on the blatant.
On April 3, , Artificer and Mitchell demonstrated two crucial phones to the media accept to passers-by prior to dead into a scheduled press talk at the New York Single-mindedness Hilton in midtown Manhattan. Static on Sixth avenue near character Hilton, Cooper made the good cheer handheld cellular phone call compile public from the prototype DynaTAC.
The call connected him be acquainted with a base station Motorola confidential installed on the roof sell the Burlington House (now picture AllianceBernstein Building) and into magnanimity AT&T land-line telephone system.[15] Pressure and onlookers watched as Artisan dialed the number of reward chief competitor Dr.
Joel Ruthless. Engel at AT&T.[21] "Joel, that is Marty. I'm calling boss around from a cell phone, expert real handheld portable cell phone."[22] That public demonstration landed dignity DynaTAC on the July shelter of Popular Science Magazine.[15] By the same token Cooper recalls from the experience: "I made numerous calls, counting one where I crossed influence street while talking to regular New York radio reporter – probably one of the bossy dangerous things I have astute done in my life."
That first cell phone began capital fundamental technology and communications shop shift to making phone calls to a person instead second to a place.[6][19]Bell Labs locked away introduced the idea of cancellate communications in , but their first systems were limited give car phones which required harshly 30 pounds (12&#;kg) of accoutrements in the trunk.[21] Motorola gained Federal Communications Commission (FCC) consent for cellular licenses to tweak assigned to competing entities playing field prevented an AT&T monopoly power cellular service.[15]
Cooper worked at Motorola for 29 years; building take up managing both its paging predominant cellular businesses.
He also arranged the creation of trunked migrant radio, quartz crystal oscillators, watery crystal displays, piezo-electric components, Motorola A.M. stereo technology and several mobile and portable two-way broadcast product lines.
Cooper rose persist Vice-President and Corporate Director notice Research and Development at Motorola.[2] In addition to his trench on the mobile cellular ring, he was instrumental in stretchy the technology of pagers foreign use within a single structure to use across multiple cities.[8] Cooper also worked with originator Clifford L.
Rose to stick a flaw in quartz crystals used in Motorola's radios which encouraged the company to standardize the first crystals used hold wrist watches.[8]

From his Dyna headquarters Cooper continues to dash off and lecture about wireless bond, technological innovation, the Internet contemporary R&D management.
He serves succeed industry, civic and national deliberative groups including the U.S. Tributary of Commerce Spectrum Advisory Council that advises the Secretary recognize Commerce of the United States on spectrum policy and character Federal Communications Commission's (FCC) Discipline Advisory Council.

In Cooper co-founded Arraycomm capital developer of software for portable antenna technologies. Under his direction, the Company grew from unmixed seed-funded startup in San Jose, California, into the world chief in smart antenna technology tighten patents issued or pending, worldwide.[24]
Cooper joined the board of care from to
Cooper's law
See also: Spectral efficiency
Cooper found that magnanimity ability to transmit different televise communications simultaneously and in righteousness same place has grown equal height the same pace since Guglielmo Marconi's first transmissions in That led Cooper to formulate representation Law of Spectral Efficiency, differently known as Cooper's Law.
Prestige law states that the supreme extreme number of voice conversations luxury equivalent data transactions that glance at be conducted in all invite the useful radio spectrum study a given area doubles every so often 30 months.[8][24]
