“The capacity, cost per megabyte and quality of service of existing 3G cellular technologies –including EV-DO Revision 0 on CDMA2000 networks and High Speed Packet Access (HSPA) on W-CDMA networks – are not yet adequate to support a significant move to wireless VoIP services,” notes the report’s co-author, Mark Heath. “However, EV-DO Revision A and 3G LTE will respectively create the cost benefits and new service opportunities that trigger the migration to mass market cellular VoIP.”
Key findings from the new report include:
- By 2015, cellular VoIP will carry 28% of all fixed and mobile voice minutes in the USA and 23% in Western Europe
- Mobile operators will position cellular VoIP as a premium voice service, emphasising quality of service and a range of value added features (such as presence information, instant messaging and multimedia sharing) in order to resist the erosion of voice prices
- Cellular VoIP will dominate the mix of wireless VoIP services in developed markets, with VoIP over wireless local area networks (VoWLAN) and VoIP over broadband wireless access (BWA) technologies (such as WiMAX) relegated to niche roles.
According to report co-author, Alastair Brydon, mobile operators need to start planning for the transition to VoIP services now, “Operators need to consider the migration to all-IP core networks and the introduction of VoIP-enabled handsets, as well as the evolution of their radio networks.”
Operators must also manage the threat of third parties that offer VoIP on operators’ own cellular data services, as well as competitors that offer alternative VoIP services on WLAN or BWA networks. This report discusses the factors that will define when wireless VoIP services become significant. The report also forecasts the impact of wireless VoIP on the overall market for fixed and mobile voice services over the period 2006–15, both in terms of voice minutes and revenues. The report considers the relative importance of VoIP over cellular, WLAN and BWA technologies and identifies the barriers and enablers to their respective success.
