Course Overview:

VoLTE Performance Optimization Training Course Description

VoLTE offers a standard for voice and messaging over LTE, provides for handover from/to legacy networks, allows the carriers to use an economical mix of available technology options (2G, 3G, or 4G), and helps them counter the OTT threat. This VoLTE Performance Optimization Training course will help you understand and realize the potential of VoLTE. Covered in detail are VoLTE as well as alternatives technologies such as CSFB to WCDMA and CSFB to CDMA2000.

3GPP2 had originally intended LTE as an IP-based technology that would handle voice by reverting to 2G/3G or by employing VoIP. Mobile operators perceived this as a lack of standardization and are also facing increasing competition from the OTT (Over the Top) applications such as Skype and WhatsApp.

Customize It:

• If you are familiar with some aspects of this VoLTE Performance Optimization Training course, we can omit or shorten their discussion.
• We can adjust the emphasis placed on the various topics or build the course around the mix of technologies of interest to you (including technologies other than those included in this outline).
• If your background is nontechnical, we can exclude the more technical topics, include the topics that may be of special interest to you (e.g., as a manager or policy-maker), and present the course in manner understandable to lay audiences.
