Martin Cooper - Inventor of cell phone (Mobile phone)
Inviato: 8 aprile 2013, 19:30Martin Cooper (born 26th December 1928 in Chicago, Illinois, USA) was a vice president and division manager who led the Motorola team that developed the handheld mobile phone (as distinct from the car phone). Cooper is the CEO and founder of ArrayComm, a company that works on researching smart antenna technology and improving wireless networks, and was the corporate director of Research and Development for Motorola. The original Motorola DynaTAC handset, weighed 2.2 pounds and had 35 minutes of talk time. Cooper has said "The battery lifetime was 20 minutes, but that wasn't really a big problem because you couldn't hold that phone up for that long." By 1983 and after four iterations, Cooper's team had reduced the handsets weight by half. The list price was around $4,000 (2010: $10,000). Cooper left Motorola before they started selling handheld mobile phones to consumers.
