The objective of this feasibility study was to develop a framework for an evolution or migration of the 3GPP system to a higher-data-rate, lower-latency, packet-optimized system that supports, multiple RATs. The focus of this work is on the PS domain with the assumption that voice services are supported in this domain.

Note:  This feasibility study has led into work items specifying LTE/SAE and the contents of this study should be considered out of date.
