Mobile Cell Phone History – Communication Technology
Children today consider wireless phones necessary and usual in daily life. They do not know a time without common. But this was not the case in 1973 when Martin Cooper his first mobile phone of a street, the city of New York and New Yorkers looked to him yawning. But the history of the mobile phone starts later in time. The history of mobile phones and wireless communication should begin by Samuel Morse. He introduced the concept of wireless by conduction when the broadcast signal via a telegraph water. The telegraph was the first messages by electricity. Then in 1843, a man named Michael Faraday studied to see if the area can carry electricity. In 1865, a dentist, Dr. Mahlon Loomis was the first person to communicate wirelessly through the atmosphere. He came up with the idea to send and receive messages using the atmosphere as a conductor and sending kites covered with copper screens connected to the earth with the son of the buyer. Loomis received a research grant of € 50,000 by the Congress.
But let us move to the twentieth century and the invention of the mobile or wireless phone as we know it today. This brings us to a man often the father of the mobile phone, Martin Cooper. He was employed by Motorola and worked on the development of first-hand radios for the police in Chicago in 1967. He went on to carry out research on cell Motorola.
AT & T Bell Laboratories introduced the idea of mobile communications in 1947. The 60 ‘and 70 Motorola and Bell Laboratories in a race to integrate the technology into portable devices.
On April 3, 1973, Martin Cooper won the race when he’s first mobile phone to rival AT & T. Motorola introduced the 16-oz DynaTAC “phone into commercial service in 1983 at a cost to consumers of $ 3500. He weighed 2.5 kg. Took 10 hours to charge 35 minutes. Features were limited to dial, listen and talk. This is usually the Brick.
In 1977, mobile phones went public. Chicago is the first city to test mobile phones with 2000 customers.
In 1983, Motorola, with the assistance of Martin Cooper, presented the 16-oz DynaTAC “the first portable mobile phone. This phone is 15 years and a cost of more than 100 million dollars on the market. The cost for the consumer is $ 3500. He weighed 2.5 kg., Nam 10 hours to charge and allowed 35 minutes. Features were limited to dial, listen and talk.
From 1983 to late 1980 “s 1st generation of mobile phones or car because they are often very popular. Most are not in the hand, but rather installed in cars or telephones bag.
In 1988, the CTIA (Cellular Technology Industry Association) was founded.
In the early 1990s the second generation or 2G phones on the market. They were able to work on GSM, TDMA and CDMA technology. 2G digital networks online and replace the analog network frequencies making them virtually obsolete. Phones are much smaller and portable and use skyrocketed.
Currently the third generation or 3G phones, the technology available today. 3G innovations that enable them to more than just phone calls. For example, Internet access and e-mail and streaming video capability.
In December 2005, the wireless industry in the United States surpassed 200 million subscribers. In 2006 this number rose to 233 million subscribers by 12.8% of households are completely wireless. There are 195,613 cell sites make it possible.
