Mobile Phones

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 regarding the mobile phone company is the Motorola DynaTAC 8000X with its model. The model was designed by engineer Rudy Krolopp Motorola in 1983. The model weighed just under a kilo and a value of almost $ 4000. Krolopp was later incorporated to the team's research and development led by Martin Cooper Motorola. Krolopp Cooper as both appear as owners of the original patent. 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. Telephone communication is made possible by the interconnection between mobile and central government. According to the bands or frequencies on which operates the mobile phone, can function in one part or another of the world. Mobile telephony is a combination of a network of radio transmitter / receiver (repeater, base station or BTS) and a series of telephone switching 1st and 5th level (MSC and BSC, respectively), which allows communication between portable telephone terminals (mobile telephones) or between terminals and telephones in the traditional fixed network.
