While Verizon was performing its Cat-M1 Voice over LTE (VoLTE) trials, China Unicom, Ericsson and Qualcomm Technologies demonstrated the use cases for the new technology early in July at Mobile World Congress Shanghai 2017.
The demonstrations appear to use much of the same technology as Verizon’s Cat-M1 VoLTE call: Ericsson’s IoT and VoLTE capable network infrastructure and Qualcomm’s MDM9206 global multimode LTE IoT modems.
The Cat-M1 VoLTE use cases demonstrated a fire alarm trigger panel and a GPS emergency tracking device.
Fire alarm trigger panels can be configured so that a single press of a button notifies multiple first responders and stakeholders, such as the fire department, the hospital, and the building’s property management office. Using VoLTE capabilities, the person who triggered the alarm can describe the situation to rescuers and get immediate guidance.
The improved coverage and longer battery life offered by Cat-M1 technology can be used to create more reliable GPS emergency tracking devices. Such devices can use data services to send GPS location data while enabling VoLTE calls for coordinated emergency response.
During MWC Shanghai, China Unicom, Ericsson and Qualcomm engineers established a point-to-point Cat-M1 VoLTE call using Meitrack P99 GPS tracking devices powered by Qualcomm MDM9206 global multimode LTE IoT modems. Ericsson products used in the demonstration included an LTE Radio Access Network, Evolved Packet Core, IP Multimedia Subsystem and Unified Data Management.
