The Amazing History of Cellular Phones

In today's world, most people from all ages and gender communicate through the use of cellular phones. It is unbelievable that fifteen years ago or more, cell phones were a rarity. At first, cellular phones were little more than two way portable radios but as technology improved, plus the increasing demand, the concept behind cell phones improved rapidly.

Below is a progression history of cell phone technology:

? 1843 Faraday exposed his advances in science and technology and his discoveries on technical development toward cellular phone development

? 1865 r. Mahlon Loomis of Virginia, USA, and a dentist had been the first to communicate through wireless communication via the atmosphere.

? 1973 Dr. Martin Cooper is considered the inventor of the first portable handset. He is the former general manager of system division at Motorola. Dr. Cooper is the first person to make a call using a portable cellular phone, and with Motorola Dyna-Tac, they took the cellular phone technology to show it to the public.

Bell labs and Motorola made their race in competing to invent the first viable cellular cell phones. Bell Company made innovative radio systems to police service cars. Their devices were too large for anyone to bring or carry. These were not also practical as a mobile phone. As for Dr. Cooper, he worked for Motorola and made the first cell phone call using a portable handset.

Within a few years, both Bell Company and AT&T came up with prototypes of their own. Chicago and Tokyo were the first cities where cell phones were used but its availability was limited. They distributed cell phones in 1979 on trial just for 2000 customers in Chicago.

? 1977 Cell phone testing began. Chicago was the first where trials began and later other trials appeared in Washington DC and Baltimore. Japan started testing in 1979.

? 1987 In USA, over one million uses cell phones. In the US, the FCC regulates and allocates radio bandwith for different purposes. The radio spectrum is limited and can become full, so it is necessary to control that gets use of different parts of it.

The area that was licensed for cellular phones, at 800 MHz was quickly crowded. By the end of 80's this had been achieved of efficient ways to utilising the bandwith they had been achieved and cell phone age we now know got underway.

2009 The cell phone industry continuously became the most productive ones, despite the financial crisis that had taken the world market. Most producers of cell phones; namely:

? Nokia

? Samsung

? Motorola

? Siemens

? Sony Ericsson
