China Unicom, Ericsson and Qualcomm Technologies have demonstrated Cat-M1 Voice over LTE (VoLTE) use cases at Mobile World Congress Shanghai 2017. Two Cat-M1 VoLTE use cases demonstrated were a fire alarm trigger panel and a GPS emergency tracking device.

The demonstrations were conducted using Ericsson’s IoT and VoLTE capable network infrastructure; IoT devices integrated with Qualcomm MDM9206 global multimode LTE IoT modems, and China Unicom’s radio spectrum and verification of the technology and multi-service capabilities.

Guanglu Shao, executive director and senior vice president, China Unicom, said: “China Unicom aims to drive the development of the IoT and accelerate cellular network development and large-scale business implementation by constructing the leading 4G FDD network. We launched NB-IoT on a pre-commercial basis on May 12 in Shanghai. This cooperation on eMTC with Ericsson and Qualcomm is a new venture intended to boost social intelligence and the Internet of Everything through wide cooperation and the construction of leading networks.”

Frank Meng, chairman of Qualcomm China, said: “We are pleased to have successfully demonstrated the great potential and unique advantages of VoLTE on LTE IoT Cat-M1 to support new IoT applications and service areas, especially for use cases requiring voice. Our LTE IoT modem solution is designed to support the low-power, cost-efficient and global deployment required by many of these IoT applications. We look forward to working with key ecosystem leaders, including China Unicom and Ericsson, to quickly bring the benefits of LTE IoT to people and organizations everywhere.”

“Ericsson is committed to leading the development of the IoT and creating various IoT businesses with global operator customers. With our advanced network evolution technology, global scale and rich experience, and as China Unicom’s strategic partner, Ericsson aims to boost China Unicom’s IoT development strategy and empower the full potential of the Networked Society,” Chris Houghton, head of market area North East Asia, Ericsson said.

Cat-M1, or LTE Category M1, is a radio technology that offers benefits such as high mobility, low cost, wide coverage, flexible deployment and low latency. Adding VoLTE support to Cat-M1 ensures devices based on this technology have the capability to make voice calls. With CAT-M1 VoLTE, operators can deploy low-cost networks while meeting demands for diversified mobile broadband and communication services use cases for the IoT.

China Unicom, Ericsson and Qualcomm have previously demonstrated a Cat-M1 call on China Unicom’s network in Beijing.
