Abstract
This paper investigates the spectral coexistence between UMTS and EDGE Mobile Radio Networks. The simultaneous operation of these two different 3rd Generation Radio Access technologies in the same frequency band and in the same area offers interesting perspectives regarding 'soft' migration scenarios from existing 2nd generation networks towards IMT-2000 compliant services. Specific features of the respective systems are modeled and a sample scenario is presented, focusing on a UTRA-FDD speech service and the packet-switched EGPRS-bearer. The analysis concentrates on QoS-parameters from a user's point of view, like the Bit Error Ratio (BER) for speech connections and Per-user-throughput for the packet switched service. Furthermore, it is shown that an overlayed UMTS/EDGE network can have a higher spectral efficiency than one single UMTS or EDGE network. Finally, a recommendation on boundary conditions which allow the coexistence of the aforementioned systems is given and a system-spanning control of services, traffic load and thus of interference which could be managed by an 'Integrated Radio Resource Management' for both systems is suggested. In this context, a particularly important issue would be the application of a combined Power Control mechanism in both networks and its positive influence on the mutual interference between both systems
