ABSTRACT: 

      From the time of telegraphs the telecom sector has witnessed an immense growth and has diversified into various segments like, fixed line telephony, mobile telephony, GSM, CDMA etc. This industry is growing at a faster pace than any other sector for the recent years by introducing modern technologies which traveled far and wide and genuinely nurtured by the public. This growth extends up to the network operators and handset providers introducing newer value added services and latest technology cell phones with advanced multimedia applications.

      It’s high time to induct, acknowledge and learn about the much-awaited 3G Technology.

      3G is the third-generation technology also known as UMTS (Universal Mobile Telecommunications System in the context of mobile phone standards. The third generation, as its name suggests, follows the first generation (1G) and second generation (2G) in wireless communications. The services associated with 3G provide the ability to transfer simultaneously both voice data (a telephone call) and non-voice data (such as downloading information, exchanging email, and instant messaging). The first country that introduced 3G on a large commercial scale was Japan. 3G networks are wide area cellular telephone networks which evolved to incorporate high-speed internet access and video telephony. Handsets could vary from wrist-watch style 'simple' telephones to palm-pilot type for multi-media web-browsing usage.

This is important because different vendors use different...
