September 21 2007: Cedar Point, a VoIP player in the cable market, has announced it’s deploying a voice-over-WiMAX network in Equador. Voice may be an ideal application for WiMAX and even for municipal WiFi because its bandwidth is low enough to insure that service quality won’t deteriorate under load. For WiMAX, the lower bit rate per customer can mean very large service geographies, up to the theoretical limit of about 30 miles radius. The main issue for VoWiMAX will be spectrum availability in the developed markets. In third-world deployments where there is little spectrum competition and mobility is less significant, WiMAX is a very good choice even for voice alone. For developed economies, 3G mobility is financially attractive and shares the same general spectrum requirements. For both 3G and WiMAX, there are still questions of how the shared-bandwidth nature of the service can accommodate the varying loads of users.
