Children today consider cordless phones to be necessary and commonplace in everyday life. They can not have time without being spread. But that was not the case in 1973, when Martin Cooper launched his first mobile phone call from New York Street, and the New Yorkers stared at him. But the cell phone's story is about to start in time.
The story of cell phones or wireless communication begins with Samuel Morse. He introduced the wireless driving concept when a remote signal sent through water. His telegraph was the first device to transmit messages electronically.
In 1843, a man named Michael Faraday studied whether the place could drive current. In 1865, the dentist, Dr. Mahlon Loomis, was the first man to communicate wirelessly through the atmosphere. The idea came to send and receive messages in the atmosphere as conductor and sent dragons covered with copper wires that were connected to the ground with copper wires. Loomis has received $ 50,000 in research funding at a congress.
But let's go ahead for the twentieth century and the inventions of the cell or cordless phone as we know it today. This leads to a person who often mentions the cell phone's father, Martin Cooper. Motorola was an employee and worked in 1967 for the development of the first handheld computers for the Chicago police. He then continued the Motorola cell research.
AT & T Bell Laboratories introduced the idea of cellular communication in 1947. the 60s and 70s Motorola and Bell Laboratories were competing to incorporate technology into portable devices.
1973rd On April 3, Martin Cooper won the race when he made the first mobile phone call to AT & T's rivals. Motorola introduced the 16-ounce "DynaTAC" phone as a commercial service in 1983, and the consumer costs $ 3,500. Weighs 2.5 pounds. It took 10 hours with 35 minutes of talk time. The features were limited to dialing, listening and talking. This was commonly known as brick
In 1977, mobile phones were public. Chicago was the first city to try two thousand customers on the cellular phone.
In 1983, Motorola, with Martin Cooper, introduced the 16 ounce "DynaTAC" in 1983, the first truly portable mobile phone. This phone took 15 years and cost over $ 100 million. The cost of the consumer was $ 3,500. It was 2.5 pounds, took 10 hours, and allowed 35 minutes of conversation.
From 1983 to the end of the 1980s, first-generation mobile phones or car phones, which were often called, became very popular, most not in the hands, but rather in cars or bags.
In 1988, CTIA (Cellular Technology Industry Association) was established
In the early 1990s, second generation or 2G phones were released on the market, they were able to work on GSM, TDMA and CDMA technologies. the Internet and the replacement of analogue network frequencies have become virtually obsolete. Phones are much smaller and portable and use has jumped.
Currently, third-generation or 3G phones are today's technology, 3G phones have innovations that allow them to get more than just phone calls, such as internet access and email capabilities and streaming video.
In December 2005, the US wireless industry exceeded 200 million subscribers, and in 2006 it grew to 233 million subscribers and 12.8 percent of households were completely wireless. There are 195,613 cell sites that allow this.
