In Europe, a dispute about builds, such as networked cars are to each other and with the infrastructure at the roadside to communicate via Wi-Fi or over the cellular network.
a so-called delegated act of the EU Commission, at least initially, for the short-range Wi-Fi, on Wednesday, the European Parliament is debating. If the European Parliament or the Council of the member countries rise by the middle of may with no objections, the legal act in force.
Against this Background, the followers of the mobile solution are more active. So BMW and Deutsche Telekom in a joint letter to the Federal Minister of transport, Andreas Scheuer (CSU) called for a Veto of the act of the Commission of appeal. “Germany should urge the Council to the fact that the delegated act will be withdrawn in its current Form by the EU-Commission and re – presented in a truly technology-neutral Form,” – said in the letter that has been submitted to the dpa. “The delegated act-Europe is a technical and political dead end.”
In the act, the Commission stated that, for the communication on short distances, the Format of the ITS-G5 is Mature, tested and already in use. It is based on Wi-Fi technology, and operates in a dedicated frequency spectrum of 5.9 GHz. At the same time, the Commission sees the use of 3G and 4G mobile telephony for communication on longer distance and to the infrastructure on the roadside, such as networked traffic lights. The mobile technology for all use cases-based Format V2X, as well as the super-fast 5G wireless data could later be integrated in the act.
BMW and Telekom criticize in the letter to Scheuer, the Wi-Fi solution, only a transitional technology. “China uses exclusively C-V2X, the United States also tend to have this Standard.” This technology is “different than is often used claimed to be” already ready. And you could use the existing LTE networks, while the WLAN solution need to cost a “parallel infrastructure” with significant investment.
