What is the cellular phone we all love?

Mobile telephony, also known as cellular telephony, basically consists of two main parts: a communications network (or mobile network) and terminals (or mobile phones) that allow access to that network.

The cell phone is a wireless device that allows electronic access to the network or cellular phone. Its main feature is its portability, which allows communicate from almost anywhere. Although its main function is the voice communication such as telephone conventional, its rapid development has incorporated other functions such as camera, calendar, Internet access, video playback and even GPS.

The first precedent regarding the cell phone is the Motorola company, with its model DynaTAC 8000X. The model was designed by the engineer Rudy Krolopp Motorola in 1983. The model weighed slightly less than one kilogram and was worth nearly $ 4,000. Krolopp was later to incorporate research and development team led by Motorola Martin Cooper. Both Cooper and Krolopp appear as owners of the original patent.
