The mobile phone, or simply the handset, is a mobile telephony communication device connected to the land telephone network through various traffic stations. The handset only operates in those places where the network matches the frequency of its waves.

History
The invention of the handset is attributed to Martin Cooper, one of the best engineers of Motorola society. Martin first introduced the project on April 3, 1973. Despite the company's ambitions, the new invention still had many unconvincing elements. It was only after 10 years of efforts that the first mobile project was able to develop to the point that it came to market. The first handset went on sale for about $ 4,000.

generations
Since its launch, the mobile phone has used three different operating systems that we call generations today:

0G - Radiotelephones used until the time of the first mobile phones came out.
1G - Analog phones that only work at the same wavelength or within a given telephone network.
2G The first digital handset currently known as GSM (Global System for Mobile Communications).
2.5G - GPRS (General Packet Radio System) High speed digital handsets for data exchange.
3G (III Generation) - UMTS (Universal Mobile Telephone System) Cameras equipped with photo and video cameras.
Thanks to these handsets, conversations are not only possible with listening, but also for viewing, without forgetting and sending video and audio format messages. Recently, third generation handsets have enabled internet connection thanks to WAP (Wireless Application Protocol) system. Here we must not forget listening to the radios or watching the various televisions, of course if this service is provided by the telephone company with which the individuals are contracted.

So the G3 handsets are the last word in telecommunications technology. The development has also enabled the connection of the mobile device to the computer enabling not only data exchange but also their storage such as: mobile number, sms with affective value, photos, videos, etc.

Social aspects
During the second half of the 1990s, the cellphone became a status symbol, but with its rapid expansion it became one of the most indispensable objects of everyday life. According to statistics from a European society, Italy is one of the countries where mobile has become a craze. But this development has undoubtedly brought about its effects. In the culture of many countries it is described as inappropriate behavior:

If the cellphone ringtone volume is high
Talking on the phone loud enough to force the other to listen.
Keeping your cellphone open in cult or public places (theater, cinema).
But based on statistics 34% of mobile users find it difficult to predict which ringtone their device will ring so different friends set different ringtones. Some users claim to think shortly before making a call to think about whether the schedule is appropriate, both for the price of the call and not to disturb the other. However, there are many people who turn off the device or reject the call if they are unable to communicate with the caller.

risks
Many health protection associations declare that mobile causes problems in certain groups of individuals (interesting women or children who have a direct impact on the brain as it is still unformed). To the rest of the people if the cell phone is used in a restrained and normal manner the damage is certainly reduced. For many charities that raise funds to fight cancer, using a cell phone is dangerous. Given that these associations are funded by 1/3 of the mobile phone companies' revenue, they often declare that the risk is relative by passing on a conflict of interest.

In June this year, the French Health Protection Agency (L'Agence Francaise de Sécurité Sanitaire) released a statement saying that studying the risk of mobile phones took time because their rapid development did not allow such a thing. But that agency did not exclude the risk of mobile phone waves.
