The mobile phones are
thus named because above all they are mobile. They can be carried anywhere and
used anywhere. However, the mobile phones have another name, that is, the cell
phones. The name cell phone is derived from the fact that these phones operate
on cellular technology......
A mobile phone is a device that is or
once was only used to make and receive calls. It does so over a radio link by
connecting to a cellular network provided by a mobile phone operator.
However, in today’s world, a mobile
phone is used for much more than just making calls. Mobile phones were created because of people’s need to
communicate even while outside their homes where telephones are usually placed.
They were intended for use in cars or automobiles, hence the name mobile phone.
They get their power from the vehicle’s battery and are equipped with antennae
that connect with a service provider that has cellular sites along a wide range
of areas.These now commonly accepted and demanded
features include text messaging (SMS), MMS, email, GPS, EDGE, GPRS, Bluetooth,
Wi-Fi, radio, MP3, MP4, video recording, internet browsing, downloads, gaming
and photography. Mobile phones offering all theses features and more are called
smartphones.
Cellular technology denotes that the entire coverage area of a Base station is divided into many cells to implement frequency reuse. While, a cell phone is the proper name for these devices, many people did not know the origin of the name, and most didn’t care. Since, the most popular feature of the device was its mobility, the term mobile phones got more popular and was easier to promote.
Hence, the device is now commonly called a mobile phone in most parts of the world. The name cell phone is still commonly used in some parts of the world, especially in countries, where the cell phone was first commercially launched under this name, such as in North America.
The first hand-held mobile phone was demonstrated by John F. Mitchell and Dr Martin Cooper of Motorola in 1973. That handset weighed approximately 2.2 pounds (1 kg). The first mobile hand set that was used to make calls was available in Japan in 1979 by NTT. These worked in the metropolitan area of Tokyo.
