• 車聯網V2X是以應用為導向的通訊技術,從早期的Telematics使用2G/3G/4G的技術開始,2000年左右美國運輸部開始推動DSRC技術以及相關道路安全應用,直到2016年3gpp於Release 14開始訂定C-V2X車聯網技術標準,V2X技術以及相關的智慧交通與自駕車議題在這個過程中受到大眾愈來愈多的關注。
• 簡報中將介紹國內DSRC以及C-V2X通訊技術的開發現況。同時,由於車聯網V2X是以應用為導向的通訊技術,簡報中也會介紹國內相關應用以及網路佈建的狀態和後續的規劃。

Three Scenarios in 5G URLLC is one of the three scenarios (eMBB, mMTC, URLLC) of 5G services
defined by 3gpp:Autonomous car and smart traffic are important application of URLLC。eV2X is one of 5G key application
• Lower Latency• High Reliability• High Mobility
URLLC for Vehicle Applications

DSRC vs C-V2X in US V2V NPRM– DSRC mainly adopted in US (IEEE-1609 and 802.11p)、Japan (ARIB
700 MHz) and Europe (ETSI ITS-G5),• Architecture and Application are V2V (5.9 GHz – Road Safety),• Supported by C-ITS operators and car vendors,ex: Toyota & VW。
– C-V2X (3gpp) mainly adopted in China and Europe,• Architecture and application are V2I (Cloud)、V2V (Licensed band – New
Business Model) and V2V (5.9 GHz – Road Safety) ,• Supported by Mobile Operators and car vendors,ex: Audi & BMW
Supporters of Both Standards exist ITRI has prepared solutions for both technologies
ICL-U has involved in both DSRC and C-V2X– (EU)C-ITS operators have proposed the concept of Hybrid
Communication for future ITS services
