"Present 3G capability to cater for subscriber demand for high data rate and QoS (Quality of Service) is substantially less than 4G networks. It is expected that 3G networks will not be able to meet the needs of services like video-conferencing, full motion video etc in terms of QoS. 4G networks provide subscriber with a higher bandwidth (5GHz), and mobile data rate greater than 100Mbps. However all these could be achieved along with interoperability and seamless mobility with high QoS in a single hand held terminal in 4G heterogeneous environment by using cross-layer feedback design."
