Dr. Martin Cooper Engineer, and Inventor of the Mobile Phone Who is he? The son of Ukrainian immigrants Cooper grew up in Chicago and earned a degree in electrical engineering at the Illinois Institute of Technology. After four years in the navy serving on destroyers and a submarine, he worked for a year at a telecommunications company. Hired by Motorola in 1954, Mr. Cooper worked on developing portable products, including the first portable handheld police radios, made for the Chicago police department in 1967. He then led Motorola's cellular research. Motorola Introduces World’s First Java-Linux-Handset,A760 The Motorola A760 is the world’s first handset combining a Linux Operating System (OS) and Java™ Technology, with full multimedia PDA functionality. Worlds Smallest GSM/GPRS Chipset-Launched Skyworks has unveiled the world's first complete handset radio system that fits into a single, dime-sized package. It saves handset designers significant space, cost and design-cycle time while providing a roadmap for quad-band and 3G handsets in the future. The history of the cell phone shows that Nathan Stubblefield had a patent in 1908. However the patent was for cave radiophones and not the mobile device, as we know it today. First Generation Phones Cooper’s invention was patented on October 17, 1973. the first phone call was made by Cooper months before he applied for the patent, on April 3, 1973. He made the call to Dr. Joel Engel, a researcher at AT&T’s Bell Labs. Cooper was working at Motorola at the time, and the call was made with several media people present. The First Cellphone (1973) Name: Motorola Dyna-Tac Size: 9 x 5 x 1.75 inches Weight: 2.5 pounds Display: None Number of Circuit Boards: 30 Talk time: 35 minutes Recharge Time: 10 hours Features: Talk, listen, dial Second Generation Phones The next stage in the history of the cell phone was the development of 2G (second generation) phones. Among the earliest 2G phone systems were GSM, IDEN, and IS-95. GSM networks started appearing in 1991 (specifically in Finland). Compared with the early cell phones, 2G phones had digital circuit switched transmissions. More importantly the phone to network connection was much faster. Not only was 2G gaining ground, but the design was changing as well. As the cell phones became more powerful, their physical size was being reduced as well. It made usage much easier. Size shrinkage became possible for two reasons. One, technology made it possible to fit in more circuitry in smaller chips. Secondly, cellular sites became more powerful. 2G phones also introduced the concept of SMS text. SMS was first tried out in Britain. The first text message was done in Finland in 1993. 3G Phones Designs for third generation (3G) began after 2G phones became the standard. Japan became the first nation to try a 3G network in May 2001. A few months later in October NTT DoCoMo in Japan launched the 3G networks commercially. The following year 3G networks with CDMA2000 technology appeared in South Korea. At the beginning of 2003, 3G networks appeared in Europe. These networks first appeared in Britain and Italy. He told Click that producing the first phone cost Motorola the equivalent of $1m (£650,000) in today's money. "We had to virtually shut down all engineering at our company and have everybody working on the phone and the infrastructure to make the thing work," he said. "Even by 1983, a portable handheld cellular telephone cost $4,000 (£2,600), which would be the equivalent of more than $10,000 (£6,500) today. "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." Bring freedom Handheld phones were originally produced to help doctors and hospital staff improve their communications. He hoped the devices would help bring safety and freedom to people, but the eventual social implications were beyond his understanding almost four decades ago. Modern monster A new generation of so-called smartphones have revolutionized the mobile phone industry and changed the way people use them. The technology in handsets has shifted in focus from voice calls to include other functions such as a portable media player, web browser and camera among others. 'Slave' implant As mobile phones go to a fourth generation, with new features in each update, the inventor of the handheld phone said the handset of the future should aim to improve a user's quality of life. "Technology makes your life better, more convenient, safer, educates you, entertains you, and mostly makes you more productive," said Mr. Cooper. "The future of cellular telephony is to make people's lives better - the most important way, in my view, will be the opportunity to revolutionize healthcare," he added.
