A mobile phone is a device that can make and receive telephone calls over a radio link while moving around a wide geographic area. “The mobile phone was first invented in 1940, but it was only available for some companies” . “In 1973 Jhon F. Mitchel and Dr Martin Cooper demonstrated the hand-held mobile phone, which was weighing around 2.2 pound (1kg)” , and it become commercially available in 1979. The availability of mobile phone in the society effect the use of mobile phone increase rapidly, “From 1990 to 2011, worldwide mobile phone subscriptions grew from 12.4 million to over 6 billion, penetrating about 87% of the global population.”

The mobile was invented in 1940 and in 1973 the world’s first mobile phone call was made. In 1940 the mobile phone only available for some companies. In 1973 Motorola became the first company to produce hand held mobile phone. On 3rd of April 1973 Martin Cooper, a Motorola engineer and executive, made the first mobile telephone call from handheld subscriber equipment in front of reporters, placing a call to Dr. Joel S. Engel of Bell Labs. At that time the mobile phone take 10 hours to charge and only offer 20 minutes talk time. Because of the limited time, people barely use mobile phone to call for long period of time; therefore they only use mobile phone for emergency call.

Remember that the world’s first mobile phone call was made in 1973, and commercially available in 1979. In 1979 the world first commercial automated cellular network was launched in Japan. In 1981, this was followed by the simultaneous launch of the Nordic Mobile Telephone (NMT) system in Denmark, Finland, Norway and Sweden. After that the DynaTAc mobile phone launched on the first US 1G network by Ameritech On 6 March 1983. In 1991, the second generation (2G) cellular technology was launched in Finland by Radiolinja. Ten years later, which was in 2001the third generation (3G) was launched in Japan by NTT DoCoMo.

The use of mobile phone keeps increasing every year, after Australia’s first mobile phone system began in 1981. They attract 1300 customers and in 1992 the mobile phone services in Australia increase to 635,000. In 2007 the mobile phone services in Australia increase to 19.76 million and in June 2012 it reached 30.2 million mobile services.

Back to forty years ago people barely use mobile phone, there were only companies used it. The size of the mobile phone back then was pretty huge for people to carry around. Other than that it took ten hours to charge and offered just 20 minutes talk time, so they only use mobile phone for emergency call. Due to advance of the Technology the use of the mobile phone change rapidly and become significant in the society. Currently people use mobile phone for several purposes other than communication.

Based on my phone log, I rely on the mobile phone; I use mobile phone as my main device for communication. Other than that I also use mobile phone for clock, alarm and as a mp3. So besides of being communication device, the mobile phone can also become an entertainment device.

I cannot imagine living a life without mobile phone, forty years back the mobile phone was just a long distance communication device, which only offered 20 minutes, talk time. Now the mobile phone is significant in people’s life.
