The continued global schism between cellular and 802.11p WiFi for V2X communications has loomed large at CES 2019 this week. The two highlights in this context were Qualcomm’s announcement of the first cellular C-V2X testing in Las Vegas in partnership with Ford, and Visteon Corporation’s launch of the first dual-mode V2X module supporting both options. Visteon’s module supports both the 3GPP’s Cellular-V2X (C-V2X) based on the earlier LTE-V2X and the IEEE’s somewhat confusingly named ITS-G5 utilizing the 802.11p WiFi, which is often known as DSRC in the US, after the RF band it is used in. The shared letters in 5G and ITS-G5 are a little confusing, because it is C-V2X rather than ITS-G5 that is being aligned with emerging…
