Abstract
The voice-over-Internet protocol (VoIP) service is expected to be widely supported in wireless mobile networks, though its feasibility and capacity have not been studied in relation to the emerging IEEE 802.16e orthogonal frequency division multiple access (OFDMA) system. Using analytical and simulation models that we developed, we present the downlink performance of VoIP services over an IEEE 802.16e OFDMA system
