THE BLACKBERRY PHONE "that revolutionized the world of telecommunications"

Man is a creature that evolution achieved amid a necessity, one of them is that I have to invent a means by which he could communicate instantly and accurately, an element that has been growing and becoming more useful and practical, with variety according to the tastes, needs and requirements of the population.The invention of the mobile phone, goes back to the beginnings of World War II, where he saw it was already necessary distance communication, that is why Motorola company created a team called HandieTalkie H12-16, which is a computer that allows contact with the troops via radio waves whose frequency band at that time did not exceed 60 MHz.
During that period and 1985 began to refine and shape the features of this revolutionary new system for ease of communication of people separated by long distances. So in the 1980s it was occupied by building a team similar to HandieTalkie resources but that was intended for people who were usually big business and should be reported, this is where you create a wireless phone and a milestone in the history of wireless components since this team could talk at any time, anywhere.
In 1981 the manufacturer Ericsson launches the NMT 450 (Nordic Mobile Telephony 450 MHz). This system was still using analogue radio channels (frequencies around 450 MHz) with frequency modulation (FM). It was the first system in the mobile world as it is understood today.
1G teams may seem bulky by today's standards but it was a breakthrough for its time, as it could be moved and used by a single person.
In 1986, Ericsson upgraded the system, leading to the level NMT 900. This new version worked almost the same as above but at higher frequencies (around 900 MHz). This made it possible to serve a greater number of users and advance the portability of terminals.
In the 1990s the second generation born, using systems such as GSM, IS-136, iDEN and IS-95. The frequencies used in Europe were 900 and 1800 MHz
The development of this generation has as its cornerstone the digitization of digital communications that offer better voice quality than analog and also increases the level of security and simplifies manufacturing Terminal.
With all this technological progress appears more advanced communication device that enables not only communication but becomes an important working tool for business people and business.
The ubiquitous BlackBerry mobile communication device which was created by Research in Motion (RIM) of Waterloo, Ontario. History was made when RIM was founded in 1984 by a pair of engineering students, one each from the Universities of Waterloo and Windsor. RIM was the leading developer of wireless data technology in North America and has created several wireless products, including point of sale of wireless devices, radio modems, and the first two-way pager messaging.
In 1998, there was a call WirelessHandheld RIM 950 RIM handles email, contacts and calendars with integrated QWERTY keyboard. RIM forged alliances with several wireless service providers and software and hardware companies along the way.
In 1999, the Blackberry wireless email, BlackBerry 5790, was revealed along with the BlackBerry Enterprise Server (BES) for Microsoft Exchange. The BES provided the conduit between the mobile and the company Exchange mailboxes, contacts and calendar, bringing current business email in the hands of mobile workers. The new updated content on the mailbox was "pushed" to the BlackBerry keeping the worker up to date. The fully integrated first phones were shipped with the 6200 series after the 5810 and 5820 phone functionality provided only with an external headset. RIM has also expanded its coverage of the GSM network to add CDMA.
The 7000 series brought the first color LCDs BlackBerry line. Focus has also been extended enterprise customers a wider consumer market. To help compete SureType developed RIM assigning two letters per key, but using the QWERTY format, to produce a narrower device along the lines of standard mobile phones. The 7000 series also saw the first versions with WiFi (7270) and Bluetooth (7290) features.
 The 8000 series adds names to some of the issues with the BlackBerry Pearl, BlackBerry Curve and BlackBerry Bold. Cameras and media players are common between releases of this series of devices as well.
This phone, digital agenda and minicomputer has become a useful and necessary for all users that have evolved with the invention of new and modern handsets, Mr. Octavio Rendon, who lives in New York City and these day is visiting in the city of Medellin (Colombia), said to be very boring because everything is in your town can be done through your mobile device, but Colombia is a developing country and still do not have such advanced technology .
This is only a sample of what will be the world once these mobile phones are those that are marketed worldwide, not only have the ability to communicate with people who are away, the facility will also have access to all loslugares in your pocket, purse or wherever these phones are loaded.
