4G refers to the fourth generation of cellular wireless and is a successor to 3G and 2G standards. By using 4G technology you could download an entire movie in about a minute. A 4G system may upgrade existing communication networks and is expected to provide a comprehensive and secure IP based solution where facilities such as voice, data and streamed multimedia will be provided to users on an “Anytime, Anywhere” basis and at much higher data rates compared to previous generations. This 4G systems, the next generation of their old 3G systems which has 384 Kbps downloads and 129 Kbps uploads, could receive data at 100Mbps on the move and at up to a gigabit per second while static. 4G is being developed to accommodate the QoS and rate requirements set by forthcoming applications like wireless broadband access, MMS, video chat, mobile TV, HDTV content, minimal services like voice and data, and other services that utilize bandwidth.

4G features
According to the members of the 4G working group, the infrastructure and the terminals of 4G will have almost all the standards from 2G to 4G implemented. Although legacys systems are in place to adopt existing users, the infrastructure for 4G will be only packet-based (all-IP). Some proposals suggest having an open Internet platform. Technologies considered to be early 4G include: Flash-OFDM, the 802.16e mobile version of Wi-Max, and HC-SDMA.
