According to Deloitte, the voice-based service worldwide will surge double the amount year-on-year, with 100 carriers offering, at least, one packet-based VoLTE or VoWiFi services to the customers. There will be around 300 million customers for VoLTE and VoWiFi services, predicts the company.
In order to meet the surging demand for VoLTE and VoWiFi services in 2016, carriers will focus on enhancing their capacity and coverage. Improving the capacity will help the carriers to move voice calls from 2G and 3G networks to LTE (4G) network. The LTE networks are capable of supporting up to twice the users in a given bandwidth.
Shifting to VoLTE will also bring improvement in the quality of services. The subscribers can use data connections while being on call, there will be a serious reduction in call drop, the calls can be established much faster and also, there is a feasibility to switch to video call if desired.
Similarly, unlike the VoIP services, VoWiFi services do not require a mobile application for its operation. No call disconnection issue arises as the service is entirely managed and controlled by the network operator.
According to Deloitte, the customers maintain high expectations from the services. Hence, it’s suggested that the services are launched only when they are stable. The coverage extension has to be done internally as the majority of calls are made indoors. However, providing a good coverage indoors will be technically complex and expensive.
For marketing the services, Deloitte suggested that the operators should advertise VoLTE and VoWiFi services by focusing on the quality of voice calling, enabling them to perceive the enhancements provided as the value added services. This could bring back the subscribers to calling, who have moved to OTT alternatives nowadays.
