Evaluation of the recent advances of the evolved 3G (E-UTRA) for the VoIP and best effort traffic scenarios

The evolved UMTS terrestrial radio access (E-UTRA) is a new technology being standardized by the 3GPP . E-UTRA targets for a long term evolution of 3G UMTS. This paper addresses the fundamentals of the E-UTRA technology and describes especially its gain mechanisms. As the standardization work is progressing rapidly, this paper does not focus on comparing the specific proposed schemes, but instead aims at outlining the system performance more in general. As E-UTRA operates in the packet-switched domain, all traffic is handled by packet protocols. The cellular analysis is shown with the results for a voice over internet protocol (VoIP) study case and for a best effort (BE) data study case, as these are common examples of a real-time and a non-real-time traffic, respectively. The performance is given in the number of satisfied voice users per cell and in the cumulative probability distributions of user throughput, which is scalable to the spectral efficiency.
