first mobile phone in world

'World's First Cell Phone'

40 years ago, 45-year-old Martin Cooper made the first handheld mobile call in public. On 3rd April 73, Cooper made the world's first mobile call from a Manhattan Street corner to Joel Engel, his rival in at and T. Widely regarded as the "father of the cell phone", Cooper told Engel, "I'm calling you on a real cell phone; a personal portable hand-held cell phone."

The clunky heavy phone was Motorola's dynastic 8000X far removed from the modern, ultra-thin, super-light Smartphones of today. It was 9 inches tall, an inch and a half wide and weighted 2.5 pounds - no wonder it was called "the brick". It had a battery life of only 20 minutes and a single-line text-only LED screen. It would be a decade before the phone would finally reach the hands of consumers at a looping cost of $3995. 

That was the time when cell phones were proud possessions of the elite and the wealthy. Today, cell phones have broken all class batteries. A new United Nations study has found that more people around the world have access to a cellphone than to a working toilet ! the study claims that of the world's estimated 7 billion people, 6 billion have access to mobile phones. However, only 4.5 billion have access to toilet.

Mobile phone Technology has come a long way ever since 1947 when at and T first commercialized its mobile telephone service. The service was introduced in a hundred towns - calls were set up manually by operators; to talk the user had to depress a button on the handset and release the button to listen. And it was expensive. This "0G" service was followed by the first generation (1G) analog cellular network introduced in the early 1980s, which was based on car phones and used in business. Then come the second generation (2G) digital cellular networks between 1993 and 2000. Beyond 2000, with the arrival of the third-generation (3G) Broadband data service and the internet, smartphones soon become a reality. The state-of-the-art, fourth-generation (4G) native-IP networks were standardized in 2012.
