4G Technology

Hey guyz…as we have already put a step forward in to high speed generation called 3G.

Which made us experince a faster way to communicate to the world? Now we don’t have to see the “Loading  ...” text while we open a web page.

But still there’s no word “END” to any technology. So what’s next..let ‘s know  about the next Generation called The “4^th Generation”.

What is 4G?

4G is short for Fourth (4th) Generation Technology. 4G Technology is basically the extension in the 3G technology with more bandwidth and services offers in the 3G. But at this time nobody exactly knows the true 4G definition. Some people say that 4G technology is the future technologies that are mostly in their maturity period. 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.

Some features of 4G : -

• A nominal data rate of 100 Mbit/s while the client physically moves at high speeds relative to the station, and 1 Gbit/s while client and station are in relatively fixed positions as defined by the ITU-R
• A data rate of at least 100 Mbit/s between any two points in the world
• Smooth handoff across heterogeneous network
• Seamless connectivity and global roaming across multiple networks
• High quality of service for next generation multimedia support (real time audio, high speed data, HDTV video content, mobile TV, etc.)
• Interoperability with existing wireless standards
• An all IP, packet switched network
• IP-based femtocells (home nodes connected to fixed Internet broadband infrastructure)
