The integration of heterogeneous flows in wireless mobile networks requires that new methodologies for network design and resource dimensioning be developed. We discuss a framework for the dimensioning of such networks by taking into account differentiated user and traffic profiles. Distinct QoS requirements from various applications result in different aggregate throughput per cell being achievable for the same loading factor and network layout depending on user mix. Therefore, appropriate characterization of user mixes and aggregation techniques that map these mixes into resource requirements are key in the design of third-generation systems.
