While voice revenue has remained largely flat in recent years, delivering ubiquitous, high-quality voice services remains a mandate for every mobile operator. The challenge for mobile service providers is this: How to reduce the cost of delivering voice services while increasing coverage. The solution, in large part, will come from the ability to leverage existing Wi-Fi coverage through Voice over Wi-Fi (VoWiFi) technology.
VoWiFi requires integration with a mobile operator’s core network; an evolved packet core (EPC). The type of VoWif solution you choose to deployment can have a significant impact on the success of the VoWiFi implementation.
Combining VoWiFi and NFV has a compound, positive effect:
- It expands network coverage and capacity far more cost-effective than other wireless access technologies such as RANs and added wireless spectrum;
- It allows mobile operators to accelerate the deployment of VoWiFi services through virtualization and automation, leading to a more agile and scalable business model.
In this research, ACG Research examines the market drivers, challenges, and paths to VoWiFi, including a five-year total cost of ownership (TCO) analysis that compares the present mode of operation (PMO) using purpose-built appliances versus the virtualized mode of operation (VMO) currently offered by leading vendors such as Affirmed Networks.
