The inclusion of cellular communication technologies (V2N – Vehicle2Network) into vehicles (i.e. “Connected Cars”) has been extremely successful, and since early deployments in the last couple of decades, we continue to see an expansion of how these technologies can deliver benefits for the vehicle, the driver, and other participants in the transportation ecosystem.
At present, the automotive manufacturing members of 5GAA operate more than 20 million Connected Cars that have the ability to connect to cellular networks (V2N). This V2N connection is used for a wide variety of application domains including telematics, infotainment, traffic optimization, as well as for safety applications like the recognition of slow or stationary vehicle(s) and warnings for such events as traffic jam ahead, road works and other traffic infrastructure related information, inclement weather conditions, emergency brake light and other hazard warnings. The current understanding, also based on the European C-ITS Platform Final Report, is that the nature of these warning messages is informational and the driver is responsible at all times.
As defined in the approved 3GPP Release 14 in June 2017, cellular networks are able to take another evolutionary step in the pathway to broaden the reach and applicability of benefits. In particular, this release addresses the challenges of delivering increased data volume, managing greater scale in connected devices, significantly reduced latency and providing higher levels of reliability. These defined attributes and an advanced architecture provide unprecedented support for the support of safety-critical communications, referred to as Cellular Vehicle to Everything (Cellular-V2X or C-V2X). In addition to such V2N enhancements, which rely on existing cellular networks, 3GPP Release-14 introduces the ability to support short-range communications between vehicles (V2V) and vehicle and road side infrastructure (V2I and I2V) without requiring any cellular network coverage.
3GPP Release 14 including C-V2X is also a key step to the next generation of cellular technology, 5G. Naturally C-V2X is already on a backwards compatible evolution path with enhancements being specified beginning with 3GPP Release 15.
The members of 5GAA are wholly committed to collaborating to ensure that the potential of the C-V2X technology is realized. This includes leading efforts to address key technical and regulatory issues, as well as integrating vehicle platforms with advanced cellular connectivity, networking and computing solutions.
