Verizon and Nissan have just completed the latest in a spate of demonstrations establishing the scope of Cellular V2X (vehicle-to-everything) combined with edge compute over 5G to improve road safety in various ways. These are significant in showing that C-V2X combined with roadside infrastructure will deliver many benefits even in the absence of autonomous driving, which originally provided the main motivation for it. There is the subplot that C-V2X has become the dominant wireless V2X platform in preference to the WiFi-related alternative variously known as DSRC or ITS-G5, both based on IEEE 802.11p. Neither DSRC nor ITS-G5 ever gained much traction in most Asian countries, with China in particular putting its full weight behind C-V2X from the outset. With full-blown…
