The mobile phones’ history:

The history began in the Second Mundial Word, when the people realized that they need communicated through the distances. Then Motorola’s company made an equip calls Handie Talkie H12-16, what work with avenue wave of radio.
Martin Cooper is considerate like the father of the mobile phones; he fabricated the first radio telephone in 1970, in EE.UU. They appeared in Tokyo, Japan in 1979; in Scandinavia in 1981 and in Chicago in 1983.
Just in 1980 created an equip for people, generally for successful businessman who must be communicated.
In 2001 appeared the mobile phones in colors, so the camera also. And together with this innovation appeared the text messages and late the Multimedia messages.
Finally Nokia made a games’ centre, where you can play games 3D, watch television and videos.

Generations of the mobile phone:

1º generation: created in 1979, required radio’s waves. They weigh 1kg and were very large.
2º generation: created in 1990, used Digital Technology. They had text and multimedia message.
3º generation: use in the actuality.


MY OPINION:

I think the mobile phones improvement very quickly and they are perfect communicate equips. Everybody have one. We are very used to depend of them so I think it’s impossible them disappear.
But I’m disagree to become obsessed to get the last one model because all of them are similar and just have to device to talk and communicate each other not to compete.
