It was almost agreed, but now it is off the table again: WLAN (DSRC) as standard for vehicle communication.
In April, the EU announced that WIRELESS INTERNET ACCESS will be the new communication standard in vehicle networking. But now you go back. WLAN (or also called DSRC or ITS-G5) competes with cellular (C-V2X) as communication standard,

Especially BMW and the Deutsche Telekom oppose the EU decision and shortly afterwards also the Federal Minister of Transport Andreas Scheuer (CSU). The Decision was postponed in May and now the EU countries have decided against WLAN (pWLAN or DSRC).
According to a study from Alabama, the latency is almost the same for the two standards. However, it also showed that the mobile network is easier to configure and that updates are easier to install. In the United States you have not decided yet, but there is much to suggest that DSRC is here does not come into play,
Now probably networking via mobile in the form of C-V2X prevail. This has mainly against the background of 5G a special meaning. In the face of the big one dead spots In Germany, however, that could become a problem, even though Germany had opposed WLAN.
However, it had changed Volkswagen early on WLANp set as networking standard and now has to row back. Because you wanted to equip the vehicles with this already from this year.
In China The focus is mainly on mobile communications, but this could also be related to the data aggregation for which China is known.
The most significant difference between the two competing standards is the range. While mobile radio can travel long distances, the WLAN standard is only intended for short distances. The cars should serve as relay stations.
The official decision is due today, so Reuters,
