The US regulatory workfederal Communications Commission (FCC) has implemented its scheduled plan for December 2019: It uses the car consultation PWLAN (IEEE specification 802.11p) after a long response phase the radio spectrum.
Although this only affects the US, but the decisions of the FCC often have groundbreaking character for other regulatory keeps. In Europe, the step is attracting attention, because the auto industry is split in two bearings: some companies, including the world-growing autoconzers Volkswagen, set to 11p, while others prefer the modern mobile technology C-V2X (Cellular Vehicle-to-Everything). C-V2X Grundet on mobile radio techniques LTE and 5G.
No place for two rivals
The main entity for the development of the two methods is the reduction in the number of traffic totes and at all the risk minimization in the strain traffic. For this, vehicles warn each other from hazardous situations such as sudden brakes, unsuitable construction sites or black ice and report when a rescue car crosses the way. 11P and C-V2X are not compatible, and that is the CRUX: research and policies worldwide are convinced that a uniform specification is required for car consultation.
