COURSE OVERVIEW

Voice over WiFi Training (VoWIFI): WiFi networks can now deliver mobile voice, SMS, MMS, and other media services with better QoS and lower latency. VoWiFi is now a globally interoperable and exciting IP-based voice, SMS, MMS, and video calling solution for WiFi with EPS and IMS interworking, known as VoWiFi, which also enables the development of new innovative communication services.

Traditional over-the-top (OTT) communication services solutions, such as Skype and FaceTime, introduced n VoIP, video-calling, and messaging services with little or no QoS/QoE measures in place, no handover mechanism to the 3GPP network and no guaranteed emergency support or security and safety. Traditional OTT-based services are still in need of mobile-broadband coverage to complement quality, security, and flexibility in their communication services.

Our extensive experience with VoWi-Fi has proven that Wi-Fi networks, VoIP services, and the wired network infrastructure must be properly engineered for Voice over WiFi services to work. To date, the vast majority of voice-over Wi-Fi installations have not been correctly deployed, resulting in project failure.

This Voice over WiFi Training (VoWIFI) Course provides:

  • A brief review of Wi-Fi
  • VoIP over Wi-Fi
  • Strategic and technical implementation issues
  • Hands-on practical exercises to reinforce the topics covered.

Our VoIP training courses feature substantial hands-on practicals with products from Aastra, Cisco, Microsoft, Snom, and other leading VoIP vendors.
