At the time, the failure of the picture phone, launched in the late '60s in the US by AT& T, was due to a number of causes, in this case not strictly related to the technology itself which, however recharge api already working, at least potentially. From the point of view of the infrastructure, in fact, the major technical obstacle was the fact that it can not guarantee a perfect for the whole line, and this, of course, due to the fact that the images, compared with only voice traffic.

 

Require it a greater load to the line. To this we must also add, and it is not an issue to overshadow the fact that the service was very expensive. There is also to be considered that, on the one hand technology manufacturers push faster introduction and rapid succession of in order to sell mobile recharge sites new equipment always proposing (and potentially only) phone models are very sophisticated, the other emerges clearly the fact recharge api that the lovers of technology for technology, seen almost as a status symbol, are the minority of users.

 

 The large audience of mobile devices seeking simple and inexpensive. It being understood that sometimes the technical difficulties can be an obstacle to the spread of technology, in the case of the video phone a factor which affected much has been, however, the idea that this tool could somehow violate the privacy domestic: l 'idea, in fact, to open their recharge api home to the world of having able to have control of their image was one of the major deterrents to the adoption and diffusion of this technology.

 

Currently, all mobile phone devices of third generazione4 have already incorporated features that allow the transmission of images and sounds; yet the number of users using the full multimedia services offered by this technology is history of the spread of mobile telephony, in the thirty years between its first appearance today, clearly shows the path recharge api of spread and consolidation of a technology is highly creative and uncertain outcome. This young people appear to be more users are very innovative and various mobile recharge sites research to prove it.

 

An example, which in part has been discussed useful site previously about the use of pagers in Japan, are SMS (Short Message Service), born initially as an additional service to that voice, have become today, but for teenagers Italian not only, the preferred way to communicate within the peer group. The use of mobile recharge api phones for young people that often marks the transition from childhood to adolescence, you charge so strong symbolic meanings. 

Highlights some independence from family control and, therefore, greater autonomy in communications with the group of pari6. The mobile phone also becomes a tool of construction and consolidation of personal identity and the group that, in fact, is built right around a series of important site teenagers as exclusive protagonists. If in fact the introduction of the mobile phone within the home environment has shifted, in a sense, the boundary between the public and the privato7 because even more the house is exposed to the outside world.

At the same time this means, being a tool of personal communication- even if you have the ability recharge api to call a fixed number is often preferred, in fact, make mobile recharge sites direct contact with the person sought by mobile phone, allows each family member to be able to entertain personal communications within domestic space, carving out a space within private in an environment that already looks like a niche protected.
