Introduction of 3G Wireless Technology, What is 3G Technology,

3G Wireless Technology

The technological change in mobile communications is described with a term generations (Xavier, 2001). The 1G (First Generation) technology refers to the analog cellular system which was widely used in 1980s and early 1990s. 2G (Second Generation) wireless technology refers to digital cellular system like GSM (Global System for Mobile Communications).

3G is a short form for third generation technology
and it is also written as 3-G (Wikipedia). This 3G wireless technology is used for mobile phone standards. With this technology, the mobile phone attains a capability of simultaneous data transfer of voice and other non-voice like SMS (Short Message Service), MMS (Multimedia Messaging Service), E-mails, video, etc.

3G wireless networks are different than 2G (Second Generation) and 1G (First Generation) wireless networks in terms of function and operating frequency spectrum (Xavier, 2001). Thus, in order to introduce 3G wireless network, entire new networks has to be built and mobile operators should be assigned a new frequencies.
