VoLTE call drops can be four to five times higher than calls on 2G or 3G networks, claims Amdocs in a recent research. The research is based on analysis of more than 25 million voice and data connections from 80 different network operators around the world in the past 12 months.
VoLTE is an important and strategic service for operators as it offers operating expense (OPEX) and capital expense (CAPEX) reductions through the promise of repurposing 2G and 3G services. However, this study suggests that the quality of experience VoLTE provides initially, post-deployment, can be less stable than the traditional voice service it replaces, requiring aggressive tuning by the operator.
Amdocs research also found that only 5 to 15 percent of Wi-Fi traffic going through mobile devices is able to be accurately described as Wi-Fi offload. The study highlights that service providers need to offload more traffic from cellular networks to Wi-Fi networks, in order to realize greater cost and operational efficiencies.

By leveraging the power of RAN software, service providers gain operational efficiencies and improved service agility with a centralized vendor-neutral approach.
