Abstract

Evolved UTRA (EUTRA) is currently under study by 3GPP standards organizations as a long term evolution (LTE) for current generation universal terrestrial radio access (UTRA) networks. One of the key aspects of EUTRA wireless systems will be providing voice services in packet domain using voice over IP (VoIP). This paper provides system simulation results evaluating uplink VoIP capacity for EUTRA. Simulations indicate that if efficient control signaling and scheduling mechanisms are in place, EUTRA systems can support 80 to 130 Erlangs of VoIP traffic per sector in a 1.08 MHz spectrum allocation as part of a 5 MHz LTE carrier.
