A mobile phone (also known as a cellular phone, cell phone and a hand phone) is a device which can make and receive telephone calls over a radio link whilst moving around a wide geographic area. It does so by connecting to a cellular network provided by a mobile network operator. The calls are to and from the public telephone network which includes other mobiles and fixed-line phones across the world. By contrast, a cordless telephone is used only within the short range of a single, private base station. [1]
The history of mobile phones charts the development of devices which connect wirelessly to the public switched telephone network. Early devices were bulky and consumed high power and the network supported only a few simultaneous conversations. Modern cellular networks and microprocessor control systems allow automatic and pervasive use of mobile phones for voice and data communications. [2]
