MOBILE TECHNOLOGY
The cell phone goes back to the beginnings of World War II, where it already saw that the distance was necessary comunicacióna is why the Motorola company created a team called Handie Talkie H12-16, which is a computer that allows contact with troops via radio waves at that time did not exceed more than 600 Khz.
It was only a matter of time before the two technologies Tesla and Marconi join and give light communication using radio phone: Martin Cooper, a pioneer and considered the father of cellular telephony, he made the first phone radio between 1970 and 1973, in the US, and in 1979 appeared the first systems for sale in Tokyo (Japan), manufactured by NTT Company. European countries were not far behind and in 1981 a similar AMPS (Advanced Mobile Phone System) was introduced in Scandinavia.
In 1985 he began to refine and shape the characteristics of this revolutionary new system because it allowed communicate remotely. So in 1980 came to create a team that occupied similar resources to Handie Talkie but was intended for people who were usually big business and should be reported, is where the mobile phone is created and marks a milestone in the history of wireless components since this team could talk anytime and anywhere.
The first teléfonocelular
This is the first cell phone in history, the grandfather of what we know today. His name is Motorola DynaTAC 8000X and first appeared in 1983. It was something heavy, 28 ounces (about 780 grams) and measuring 33 "x 9" x 4.5cm.. "Obviously it was analog, and had a small display LEDs. the battery was only for an hour of conversation or 8 hours in stand-by. the quality of very poor sonidoera, it was heavy and unattractive, but still, there were people who paid the USD $ 3.995 costing, making it he became a luxury and only accessible to certain social spheres, even though its design and weight.
The first to use them were businessmen, executives and staff affluent, firstly because the socioeconomic development of a company depends on being communicated effectively connected with suppliers, customers, employees, governments and regulators. Another cause of this limited use due to the high costs that these services entailed by the lack of competition among cell phone companies that force down prices and has improved technical problems.
By 1984, the company managed to sell 900,000 phones amount was intended to reach only in 2000.
History of cell phone (A through time)
Evolution and technological convergence
The evolution of mobile phone has reduced its size and weight, from the first mobile phone in 1983 weighing 780 grams, the more compact, better performing current service. The development of smaller and longer lasting batteries, sharper colors and screens, incorporating more friendly software make the mobile phone a prized element in modern life.
The advance of tecnologíaha fact that these devices incorporate features that not long ago seemed futuristic such as games, MP3 music and other formats, email, SMS, calendar electrónicaPDA, fotografíadigital and digital video, video calling, web browsing and even TV digital. Telefoníamóvil companies are already thinking about new applications for this small device that accompanies us everywhere. Some of these ideas are: a means of payment, people locator and identifier. Always keep in mind the great advances suffered from the first mobile phone to today. The stage of evolution of cellular phones can be divided into three generations:
First generation cell phones
The first generation ranging from the appearance of the first cell phone in the world market known as "brick" (DynaTAC 8000X) to late 80 These were characterized as analog technology for restricted use of oral communications. The predominant technology in this generation was the AMPS (Advanced Mobile Phone System)
Second generation mobile phones
The second generation makes its appearance in the 90s, are mostly digital technology and have certain benefits highly valued as an extended battery life, ability to be more segurosy higher definition sound. These phones, and some analog phones, have the possibility it was sent and received text messages (SMS) however, it is not yet in recent years the "boom" of this tool in recent years has amassed so unbelievable. A late fever occurs by cell phones, ordinary people are added to the list of users, favored by the exchange rate and competition between different companies.
The predominant technologies are: GSM (Global System for Mobile Communications); IS-136 (also known as TIA / EIA136 or ANSI-136) and CDMA (Code Division Multiple Access) and PDC (Personal Digital Communications), the latter used in Japan.

Third generation mobile phones
It is characterized by the above technologies together with new tecnologíasincorporadas on cell phones. The massification of mobile phones is inaugurated. In recent years mobile phones are equipped with a chip, SIM card, which is entered all the information.
One of the most important causes of the expansion in consumption up to humble societies capable of existence in the market for GSM phones what is called "low range" as the Nokia 1100, Sagem XT, Motorola C200 or C 115, Alcatel, Siemens and Sony Ericsson T106 A56, all at very affordable prices and surrounded promotions. However the need to belong, to achieve certain social status no longer present, the cell besides its communicative use is not without a nominal value of class membership, both young and senior executives who even today continue to benefit from its services. Next to these "lesser" devices an infinite variety of digital photo camera, some even allow filming minutes, have color display, lightning-fast Internet connection (EDGE), sending multimedia messages (MMS) and access to box e-mail (POP3).
In 2001 it launches in Japan's 3G phones, which are based on the UMTS (General Mobile Telecommunication services). This case was one of the final steps in what is mobile and Information. The most significant development was the addition of a second camera for video calls, ie talk to a person and see while using the mobile phone.
This change in cell means that today we are talking about a much broader market and varied accordingly. All reflected in the increasingly specific on one side and the other on the sum of promotions and plans that try to cover the entire spectrum of potential customers advertising campaigns.
