Future Mobility

Networked mobility - a clash of systems

Mobile communications or WLAN? No decision has been made as to how vehicles will be linked or connected to the traffic infrastructure in the future. A new consortium of companies is focusing on mobile communications, beginning field testing in Japan.

The specification for Cellular Vehicle-to-Everything (C-V2X) , a mobile communications technology for exchanging street and vehicle information, came into existence in 2016. Now, a consortium consisting of companies Continental, Ericsson, Nissan, NTT DoCoMo, Oki and Qualcomm is looking to begin field testing the new technology in Japan. These tests will examine suitability for practical operation, but above all, the consortium hopes to demonstrate advantages over the competing pWLAN technology , which Volkswagen uses , for example.

C-V2X will supply data on potential dangers outside of the driver’s range of vision. This information can come via the mobile communications network from the cloud online, whereas the Wi-Fi standard pWLAN enables direct vehicle communication and also includes radio beacons. But to date there is still no overarching mobile infrastructure. By contrast, C-V2X, based on mobile communications, can access an existing network infrastructure.

The tests planned in Japan are not the only field tests with C-V2X. In December 2017, Continental teamed up with Huawei testing the technology in China , and last October, Qualcomm, AT&T, Ford and Nokia announced tests in the U.S .
