Wireless Evolution with 4G Technologies

[摘要] The better the technology, the more user friendly it becomes. This is what 4G brings to us than 3G. 4G provides us 3 times faster speed than 3G technology.4G is the short name of fourth generation of wireless /mobile communication That will enable things like IP –based voice, data, gamming services & high quality streamed multimedia on portable devices with cable modem like transmission speed. The expectation for the 4G technology is basically the high quality audio/video streaming over end to end Internet Protocol. Third generation mobile, data rates are 384 Kbps (download) maximum, typically around 200kbps, and 64kbps upload. These are comparable to home broadband connections. Fourth generation mobile communications will have higher data transmission rates than 3G. 4G mobile data transmission rates are planned to be up to 100 Mbps on the move and 1Gbps stationary, this is a phenomenal amount of bandwidth, only comparable to the bandwidth workstations get connected directly to a LAN.
