4G is short for Fourth Generation wireless Technology. It is basically the extension in the 3G technology with more bandwidth and services offers in the 3G. The expectation for the 4G technology is basically the high quality audio/video streaming over end to end Internet Protocol. If the Internet Protocol (IP) multimedia sub-system movement achieves what it going to do, nothing of this possibly will matter. WiMAX or mobile structural design will become progressively more translucent, and therefore the acceptance of several architectures by a particular network operator ever more common.
After successful implementation, 4G wireless technology is likely to enable ubiquitous computing, that will simultaneously connects to numerous high date speed networks offers faultless handoffs all over the geographical regions. Many network operators possibly utilize technologies for example; wireless mesh networks and cognitive radio network to guaranteed secure connection & competently allocates equally network traffic and bandwidth.
Some of the companies trying 4G communication at 100 Mbps for mobile users and up to 1 Gbps over fixed stations. They planned on publicly launching their first commercial wireless network around 2010. As far as other competitor’s mobile communication companies working on 4G technology even more quickly. Sprint Nextel was planned to launch WiMAX over 4G broadband mobile network in United States. Some of the other developed countries like United Kingdom stated a plan to sale via auction of 4G wireless frequencies couple of years back. The word “MAGIC” also refers to 4G wireless technology which stands for Mobile multimedia, Any-where, Global mobility solutions over, Integrated wireless and Customized services.
