What is a Mobile Phone?
Mobile telephony, also called mobile phones, basically consists of two parts: a communications network (or mobile network) and terminals (or mobile phones) that allow access to that network.
The mobile phone or cell phone is an electronic device that allows wireless access to the network or mobile phone. It’s called due to the cellular antenna that make up the network, each of which is a cell, although there are satellite mobile telephone networks. Its main feature is its portability, which allows you to communicate from almost anywhere. Although its primary function is voice communication, like phone, its rapid development has added other features such as camera, calendar, Internet access, video playback and mp3 player and GPS.
The first step is regarding the mobile phone company Motorola, with its model DynaTAC 8000X. The model was designed by the engineer of Motorola Rudy Krolopp in 1983. The model weighed just under a kilo and a value of almost $ 4000. Krolopp was subsequently incorporated the research team and development of Motorola, led by Martin Cooper.

From the DynaTAC 8000X, Motorola would develop new models like the Motorola MicroTAC, launched in 1989 and the Motorola Startac, launched in 1996 to market.
