European Union lawmakers have rejected a European Commission push for Wi-Fi-based technology in vehicles and are instead backing the alternative 5G data standard, Automotive News Europe reports.

The EU is seeking to set benchmarks for internet-connected cars, in which a market for automakers, telecoms operators and equipment providers is foreseen to be worth billions of euros annually. Automakers are also divided between the Commission’s preference of the Wi-Fi-based ITS-G5 and the rivalling 5G C-V2X standard, with Volkswagen and Renault linked to the former and Daimler, Ford and PSA Group tied to the latter.

The EC’s preference for the Wi-Fi based technology will give the former group an advantage over the latter, while a clause which requires newer technologies to be modified for compatibility with older technology has caused concern in the telecoms industry, which is championing the 5G standard, as well as in other parties which are involved.

The European Parliament transport committee said the clause will be an impediment on innovation, while the commission’s digital chief Andrus Ansip, as well as Finland and Spain, have also voiced their criticism of this clause, though the EU executive reserved comment on the parliamentary vote.

The European Parliament will vote on the commission’s proposal next week, which can only be blocked by a majority, Automotive News Europe reports. The European Council also has a say in the issue, and it will need a majority of the countries in the EU to successfully counter the proposal.
