Carlos Beltrá's text on mobile telephones



The first mobile telephone



BY: CARLOS BELTRÁ


A mobile phone is a phone that can make and receive telephone calls over a radio link while 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 cell phone was demonstrated by John F. Mitchell and Dr. Martin Cooper of Motorola in 1973, using a handset weighing around 4.4 pounds (2 kg). In 1983, the DynaTAC 8000x was the first to be commercially available. From 1990 to 2011, worldwide mobile phone subscriptions grew from 12.4 million to over 6 billion, penetrating about 87% of the global population and reaching the bottom of the economic pyramid. In 2013, the top cell phone manufacturers were Samsung, Nokia, Apple Inc., and LG.

  9. I like this text so much because it´s a good learn about the history and facts of a thing that we use now, it was so interesting because there were some things that i didn't know like that the first mobile was made by motorolla not like Miguel, nevertheless a thing that i don´t like of it, was that you put all the numbers and the percentage thet was the only thing that made me feel bored.
    Congratulations Carlos you did a great job!!! :)

  11. The article give´s me information I didn't know, but is not really interesting.
    The part I like the most is when it talks about the weight of the first telephone.
    It is amazing how much technology has developed since the first mobile phone
    and also how it allows to connect two people separated by thousand kilometres.
    VERY GOOD CARLOS :)
