- Rohde & Schwarz and Huawei performed 5G V2X standard communication latency measurements in field vehicle tests in Munich and Shanghai.
- This field measurement campaign has shown that it is possible to achieve latency times in the millisecond range within a 5G telecommunications network, which is a better performance than that achieved with LTE technology.
Ultra-reliable low-latency communication (URLLC) is crucial, particularly for security applications, when using 5G for V2X (Vehicle to Everithing) communications allowing the implementation of autonomous vehicles.
Huawei and Rohde & Schwarz conducted field tests in a mobile car to measure the end-to-end delay of IP transmissions in 5G V2X communications.
A measurement accuracy of less than 2 µs for each transmitted IP packet has been achieved.
The transmitted data contained various IP traffic flows necessary for a tele-operated vehicle: video, LIDAR and control data (ITS messages). The absolute precision time standards at both ends were derived from two independent GPS receivers.
The Munich’s trial was a remote-controlled driving project, while the Shanghai trial was a V2X test site involving several vehicles driving together and communicating wirelessly. The transmission delay of an IP packet from the OTA source (over-the-air) to a mobile receiver (sink) was measured.
