The “Connected Ambulance” use case transforms an ambulance into a communication hub for transmitting the patient vital data, video and audio signals both en route to the hospital. 5G connectivity is required to properly support this use case, due to the massive capacity, reliability, low latency features needed for 4K video transmission and remote diagnostic as well as the reliability and low latency needed for patient monitoring and some basic control.
Patient Vital measurements are: Heart Rate, SPO2 blood oxygen saturation %, Skin temperature, PI perfusion index from 0.2% to 20%. These measurements are conveyed via the 5G gateway (Nokia Fastmile) to vEPC core and then via S/P gateway to the Nokia IoT platform (IMPACT). The platform then conveys the data to an application dashboard. The clock-like device which takes the patient metrics is connected to the 5G gateway via WiFi. Data is forwarded to the IoT platform. The 4K video is encoded in the streaming server, within the hardware card. Streaming is performed by OBS streaming software. Streaming data are conveyed via the 5G gateway to vEPC core and then to the S/P gateway. The IoT platform was connected to the vEPC via S/P Gateway. Patient metrics flow is be performed via the same gateway used for the 4K video data flow. Via the gateway info is to be conveyed to the vEPC and from there to the IoT platform. Installation of the vEPC, IoT platform and Radio, is located at OTE labs.
Partners involved in the trial were: Nokia, Greece; OTE.
Throughput and latency were measured between the 5G Gateway to the S/P gateway of the EPC. What would matter most in this use case is to serve the ~20Mbps upload bandwidth. Also Low latency is needed to improve QoE quality, as well as for efficient propagation of Vital metrics to the IoT platform.
