5G NR C-V2X
Ettifos to show world's first live demonstration of
5G NR V2X
Ettifos proudly presented the world's first live demonstration of 5G NR sidelink-based V2X in November 2020. The demonstration showed
Full HD video streaming for high throughput sensor data sharing use case
End-to-end latency of less than 4 msec for the ultra-low latency use case
What is Cellular-V2X?
Cellular-V2X (C-V2X) is the umbrella term which encompasses both direct communication using sidelink and network communication using downlink/uplink interface. According to the V2X applications defined by 3GPP, V2V, V2I, and V2P would be implemented over PC5 interface operating in ITS 5.9 GHz band while V2N operates in commercial licensed band over Uu interface.
LTE C-V2X and NR C-V2X
3GPP Release 14 introduced LTE-based sidelink communication operating on 5.9 GHz ITS spectrum as a potential alternative to IEEE 802.11p-based DSRC. As C-V2X standard evolves, Release 16 NR-based sidelink will offer major enhancements in the form of lower latency, higher data rate, and enhanced mobility support – which are expected to support advanced V2X use cases such as autonomous driving, platooning, extended sensors, and remote driving.
Software Defined Radio (SDR)-based C-V2X platform
Ettifos provides a SDR type C-V2X solution that can flexibly support not only LTE sidelink-based V2X (3GPP Release 14 and 15), but NR sidelink-based V2X (3GPP Release 16) in one platform. Ettifos’ SDR platform is 100% software-based solution running on top of standard Linux which supports end-to-end C-V2X data communication. This can accelerate the testing process in research institutes and also shorten development cycle times for equipment manufacturers. Ettifos showcased SDR-based C-V2X solution at past ITS World Congress and CES 2020 where successful interoperability test was demonstrated with the Qualcom’s MDM 9150 C-V2X chipset solution.
