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 whilst 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 Dr Martin Cooper of Motorola in 1973, using a handset weighing around 1 kg. In 1983, the DynaTAC 8000x was the first to be commercially available. In the twenty years from 1990 to 2011, worldwide mobile phone subscriptions grew from 12.4 million to over 5.6 billion, penetrating the developing economies and reaching the bottom of the economic pyramid.
Whippoorwills call, evenin' is nigh
Hurry to my Blue Heaven
Turn to the right, there's a little white light
Will lead you to my Blue Heaven
You'll see a smilin' face, a fireplace, a cozy room
Little nest that nestles where the roses bloom
Molly and me, and the baby makes three
We're happy in my, in my Blue Heaven
You're gonna see a smilin' face, fireplace, cozy room
And a little nest nestled where the roses bloom
Just Molly and me, and the baby is three
We're so happy in my Blue Heaven
We're happy in my Blue Heaven
