Course Details

Often associated with VoLTE (Voice over Long Term Evolution), Wi-Fi Calling is the means by which service providers can support seamless mobility between the LTE and Wi-Fi networks, whilst maintaining voice services. The course builds on the LTE System Engineering and Wi-Fi System Engineering courses and explains in detail the enhancements that need to be made to the network to support VoWi-Fi, before describing how a call is established across Wi-Fi using the services of the EPC (Evolved Packet Core) and IMS (IP Multimedia Subsystem).
