DECEMBER 202019MANUFACTURING TECHNOLOGY INSIGHTSConnecting Cars with 5Gadded cloud services (V2N or vehicle to network) and, last but not least, with passengers or the so-called vulnerable road users that are also part of the overall traffic scenarios. The 3GPP based cellular technology that enables these connections is summarized as "Cellular-V2X" or CV2X. Making Vehicles Smarter and Safer with C-V2XCommunication and connectivity are key to the development of autonomous vehicles. Cellular based technologies will be essential for transforming the entire mobility ecosystem thanks to V2X: vehicle-to-everything communication. This new protocol allows vehicles to communicate with other vehicles (V2V), pedestrians (V2P), networks (V2N) and the surrounding infrastructure (V2I).With a strong evolutionary path to 5G, C-V2X technology will offer superior performance to support connected vehicles communicate with transport infrastructure, leading to less congestion, reduced emissions and a smoother driving experience.C-V2X will additionally improve safety on roads by tremendously facilitating the flow of information between vehicles, pedestrians and road infrastructure. This will enable connected vehicles to anticipate and avoid dangerous situations, reducing collisions and potentially saving lives.Automotive and Telecommunications World Meet in the 5G Automotive Association (5GAA)One of the big challenges of the connected car is that two large industries like automotive and telecommunications have to come together to go from vision to reality. There is a full eco-system of strong players that need to work hand-in-hand to implement the vision of cooperative, connected, automated mobility: Telecommunication Service Providers, Telecommunication equipment manufacturers, car manufacturers and their suppliers, map providers, road operators ­ just to name a few. It is a true eco-system play.To start this eco-system with the right focus, in 2016 the leading car manufacturers and telecommunications companies founded the "5G Automotive Association" (5GAA). Since then, the number of members of the 5GAA has increased to almost 100 members, all following the joint goal to bring Automotive and Telecommunications together to harmonize and accelerate the introduction of intelligent transport and communication solutions. The target is to successfully implement the concepts of Co-operative Intelligent Transport Systems (C-ITS).A Quick Look into Cooperative Connected Automated Mobility with LTEAlready today, all newly released cars are connected to the back-end clouds of the manufacturers using cellular 3G/4G connectivity. These connections are now increasingly used by the technology leaders in the car industry to introduce cloud network services for traffic comfort and safety. Warnings about broken down vehicles along the roadside, vehicle accidents, variable working areas on highways and bad weather conditions are more and more becoming a reality.In 2017, version 14 of the 3GPP standards for mobile networks was released. This version enables the LTE based communication between two vehicles (V2) and between vehicles and infrastructure (V2I) with very low latency (below 50ms). Initially the focus on this technology is to enable applications for traffic safety. This LTE based communication works harmoniously with existing mobile networks, but also when the network is down or not available, thus increasing the reliability of this direct-link communication. With the introduction of the 3GPP release 14 the automotive industry has now and for the first time a unified Cellular-V2X network technology available meeting the requirements in terms of reliability, latency and flexibility. The direct communication between cars and between car and infrastructure works over a few hundred meters. It is nicely complemented by the network services (V2N) that practically work over any distance (long range). This long-range communication is based on an edge cloud architecture that builds an abstraction layer between the telecommunications and the automotive world. It hides the complexity of how cars are connected (in which cell is the car, to which service provider the car is connected, cell handovers, needed core network functions and much more) and offers an IT-like interface for the automotive industry. The automotive eco-system can then run applications on top of this edge cloud One of the big challenges of the connected car is that two large industries like automotive and telecommunications have to come together to go from vision to reality
