The Qualcomm QCP-2700, a mid-1990s candybar style phone, and an iPhone 5, a current production smartphone. A mobile phone (also known as a cellular phone, cell phone, and a hand phone) is a device that can make and receive telephone calls over a radio link while moving around a wide geographic area. It does so by connecting to a cellular network provided by a mobile phone operator, allowing access to the public telephone network. By contrast, a cordless telephone is used only within the short range of a single, private base station. In addition to telephony, modern mobile phones also support a wide variety of other services such as text messaging, MMS, email, Internet access, short-range wireless communications (infrared, Bluetooth), business applications, gaming and photography. Mobile phones that offer these and more general computing capabilities are referred to as smartphones. The first hand-held mobile phone was demonstrated by John F. Mitchell[1][2][3] and Dr Martin Cooper of Motorola in 1973, using a handset weighing around 2.2 pounds (1 kg).[4] In 1983, the DynaTAC 8000x was the first to be commercially available. From 1990 to 2011, worldwide mobile phone subscriptions grew from 12.4 million to over 6 billion, penetrating about 87% of the global population and reaching the bottom of the economic pyramid.[5][6][7][8] In the first quarter of 2012, Nokia, which had been the global market leader in mobile phones since 1998, slipped into second place with 22.5% market share behind Samsung with 25.4% with Apple Inc. trailing in third place with 9.5%.[9] In 2012, for the first time since 2009 mobile phone sales to end users declined by 1.7 percent to 1.75 billion units.[10] Contents
