CMW Cards: Enabling Mobility & Roaming Testing for Connected Cars

By Rohde & Schwarz

We are approaching a reality where autonomous vehicles are ubiquitous. These intelligent automobiles need to communicate not only with other cars, but need to connect and communicate to a larger, connected network. Cellular Vehicle-to-Everything (CV2X) is gaining acceptance from automobile manufacturers and network operators. The greatest advantage of using cellular technologies in this domain is the existing presence and coverage of cellular networks. Autonomous vehicles need to connect and communicate to neighboring vehicles, infrastructure, humans and networks. This paper provides the details about the possible vehicle-to-network (V2N) scenarios as experienced by an autonomous vehicle and methods to test them conveniently in a lab environment. Autonomous vehicles have the potential to drastically reduce, if not eliminate the number of road accidents. Authorities around the world have acknowledged this possibility and are making efforts to embrace the technology and significantly reduce the accidents and most importantly the fatalities caused by vehicles. With the idea of using technology to reduce car accidents, the U.S. Department of Transportation (DOT) recently mandated that all new vehicles be equipped with V2V communication for crash aversion. The European Parliament also took action in this area when they recently voted in favor of an e-Call regulation to go into effect at the start of 2018, requiring all new cars to be equipped with e-Call technology.

Everyday people are increasingly entrusting their safety to technology. As always, testing real life scenarios in the connected environment is essential before autonomous vehicles start driving on our roads to ensure flawless performance and the safety of the passengers. A non-reliable connectivity in the case of a vehicle could prove fatal. Sub-optimal wireless components and the inability to communicate with the surrounding infrastructure could increase the likelihood of an accident and that is before looking at the varied scenarios that these cars will be in. Other important components of the connected car ecosystem are infotainment and the telematics and both areas require reliable connectivity with the core network. Today’s consumers require uninterrupted, high definition content and the expectation that this is met every time is increasing as time goes on. The content being consumed varies in forms of video calls, audio streaming, online gaming, etc. The demand for this content is only going to increase when the autonomous car becomes a reality along with high expectations that the content consuming experience is the same as within their home. Similarly, key statistics collected by…
