Course Overview

Course in a Nutshell

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.

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 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
