4G is being developed to accommodate the QoS and rate requirements set by forthcoming applications like wireless broadband access, Multimedia Messaging Service (MMS), video chat, mobile TV, HDTV content, Digital Video Broadcasting (DVB), minimal services like voice and data, and other services that utilize bandwidth.
The 4G working group has defined the following as objectives of the 4G wireless communication standard:
A spectrally efficient system (in bits/s/Hz and bits/s/Hz/site), High network capacity: more simultaneous users per cell, 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 networks, 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, and An all IP, packet switched network. In summary, the 4G system should dynamically share and utilize network resources to meet the minimal requirements of all the 4G enabled users.
Applications At the present rates of 15-30 Mbit/s, 4G is capable of providing users with streaming high-definition television. At rates of 100 Mbit/s, the content of a DVD-5 (for example a movie), can be downloaded within about 5 minutes for offline access.
