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 and Dr Martin Cooper of Motorola in 1973, using a handset weighing around 2.2 pounds (1 kg). 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. 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%. In 2012, for the first time since 2009 mobile phone sales to end users declined by 1.7 percent to 1.75 billion units. Contents
