1. Evolution of IoT and the Role of VoLTE over Various Access Technologies

Presented by Manpreet Singh, Director Signaling and IP Architecture and Innovations Engineering, iBasis.

Currently, IoT ( internet of things ) is the new buzzword in the industry where the the day to day devices have the ability to send and receive and act on it.
Some of the most common use cases are in connected cars for telematics and in-car WiFi, connected traffic signals, connected water meters, etc. While these are very data centric applications, voice still plays a big role in enabling some of these services. These connected devices uses mobile network packet switch backbone for data and voice support. LTE and LTE-M are some of the transport networks where these devices sit on. Newer IoT devices have special chip set to support LTE-M network especially battery usage is a big deal.

Voice on connected devices is pretty much supported by Volte (SIP over IMS using Mobile transport backbone):

• Local breakout is used for voice where possible in case of roaming IoT devices
• S8/HR is used when there no LBO model is supported
• Devices have the full SIP stack supporting voice

Companies like AT&T, Verizon have already demonstrated this and chipset vendors are already supporting this.

In this presentation we will discuss the the background of IoT, use cases for data, transport networks where these services run, use of E-SIM and also support for Voice via VoLTE.
