The cellular phone industry has evolved over a period of 20 years, from first generation to third generation mobiles. The inventions by mobile industry incorporate:First Generation (1G) -The first generation mobile phone refers to the mobile phones that were developed in the 1980s. Second Generation (2G) -GSM, CDMA and TDMA are the different protocols that brought the mobile phone into the second generation stage. The 2G was introduced to the market basically in the early 1990s. Second And a Half Generation (2.5G) -Still under the same network protocol, but provided services such as WAP and GPRS enabling mobile phones to access on certain websites. Coloured screen with camera featured mobile phones were also introduced in this stage. Third Generation (3G) -A whole new network protocol launched in the twenty-first century. It is either under IMT-2000, UMTS or W-CDMA standards. The 3G protocol enables high speed connection (speed similar to broadband connection) to access through internet and also video calls.
Handsets have become a necessity from a luxury. The mobile industry has influenced the lives of millions of people worldwide. From being only a voice communication device; the mobile handset has gradually become part of user’s personality. The cellular phones have created an addition to people’s lives rather than substitution of previously existing telephony and communications systems. This system of communication has strengthened social relations through providing a voice or text mediated form of face-to face relations. The “Virtual Presence” has benefited mobile communications and it stands out uniquely from other technologies. The relationship between user and device has become much more emotional. Mobile phone is your universal microphone to the world, a way to publish pictures, emails, texts, Twitters, and blog entries. It took the mobile market, about 15 years to reach the first quarter of the world’s population but it took less than 5 years to reach to the next quarter of world’s population. The worldwide subscriber base has shown growth in recent years and has reached the 50% penetration mark in 2008. With more sophisticated devices comes more evolved usage of those devices such as sales people taking product placement and promotion audits . Built-in video devices help sales people to show off the company’s latest promotions. Now companies are not only enabling their technicians (with prompts and checklists) to capture information, but also equipping them with the necessary information to sell complementary products with appropriate packages, promotions and discounts. While it took 100 years for landline phones to spread to more than 80% of the countries in the world, their wireless descendants did it much early. So it's safe to say that the mobile phone may be the most prolific consumer product ever invented. In the last decade no other device has been diffused with humans as rapidly as the mobile phones. The invention and diffusion of information and communication technologies are said to be revolutionizing work and family life. Wireless mobile devices increase the scope for work and family flexibility by enabling the micro-coordination of time, tasks, and schedules. This is particularly significant as people are now working at times and places outside of the traditional workday and place. It is widely believed that technologies like the mobile phone and e-mail are blurring boundaries between personal life and the workplace.
While for some commentators these developments represent a threat to the quality of modern life, for others they represent new opportunities for integrating the spheres of work and family.To date, social research on the mobile phone has been limited and has yet to be consolidated into a body of evidence about its social impact. The first commercial mobile phone service was launched in Japan by NTT in 1978. By November 2007, the total number of mobile phone subscriptions in the...
