The History of Mobile Telephony
"Hey Joe, I'm talking to you from a real cell phone," he told him. "Even though we didn't have the best of relationships, he treated me very nicely," Cooper said years later in an interview. Bell got its revenge in 1978, building the first mobile phone test network, which was necessary for the development and commercialization of the mobile phone.
The first automated mobile phone network operated in the early 1980s in Scandinavia. Until the late 1980s mobile phones were bulky to carry in the pocket so they were mainly installed in cars. The first mobile phone to receive approval was Motorola's DynaTAC8000X model. It was the flagship of the so-called first generation (1G) mobile phones.

[/P]The beginning of the 90s saw the take-off of mobile phones, with the digitization of networks (GSM) and devices. Mobile phones became smaller (100-200 grams), fitting in the palm of the hand and fitting even with difficulty into the user's pocket. So we moved on to second-generation (2G) mobile phones, which offered other facilities such as sending short text messages (SMS) and taking photos.
At the beginning of the 21st century came third-generation (3G) mobile phones, with their unlimited multimedia capabilities. Today, mobile phone penetration on the planet is growing by leaps and bounds, especially in the world's poor countries, such as Africa. The number of active devices exceeds 6 billion, and the trend is upwards. The South Korean company Samsung, with a market share of 23% (December 2012), is the world leader in mobile phone sales.
