“Voice over Wi-Fi” course focuses on Wi-Fi introducing in telecom network. During the course Wi-Fi radio network is described. Signalling protocols with procedures and parameters are presented in details. IMS/RCS network nodes and nodes for sms and emergency call delivery.
The course is intended for access network engineers, network tuning staff, WiFi services responsible, and anyone, who needs deep technical knowledge on functionality of WiFi services.
