Coincidentally, several global automotive and telecommunications companies have recently completed another important milestone in the development of ChinaLian Automobile - Qualcomm, 5G Automotive Alliance (5GAA), Audi and Ford Motor Co., Ltd. have joined hands to achieve the world’s first cross-division vehicle model The C-V2X Direct Communication Technology Demonstration. This demonstration utilizes C-V2X real-time direct communication based on the globally unified 5.9GHz Intelligent Transportation System (ITS) spectrum to avoid vehicle collisions and improve road safety without reliance on Any mobile operator network.
This demonstration uses equipped with Qualcomm C-V2X chipset Audi and Ford models, showing the C-V2X different scenarios in terms of improving road safety. For example, in the line of sight or non-line of sight blocked by the lower case, the vehicle turn left or by V2V (vehicle-to-vehicle) communication provides a warning to the surrounding vehicles also include the presentation of great potential in the protection of vulnerable road users V2P (vehicle-to-pedestrian) communication with patients. demo also includes V2I (vehicle-to-base emergency brake facilities) communication technology, through direct communication with the traffic signal controller of cooperation, optimize transportation efficiency in complex intersections and traffic-intensive environment and reduce carbon emissions.
In addition to completing the technical demonstration, Qualcomm and three other organizations also jointly released preliminary results of the field test. The results show that C-V2X direct communication technology has obvious advantages in coverage, reliability and performance. Compared with 802.11p wireless technology. In comparison, C-V2X's coverage and reliability have more than doubled. Based on its enormous potential, Qualcomm and the extensive automotive ecosystem are accelerating the development of C-V2X, and it is expected to begin deployment as early as 2020.
C-V2X technology has obvious advantages, commercial deployment is poised for development
The C-V2X is a global solution for V2X communications designed to enhance vehicle safety, improve automated driving, and improve traffic efficiency. C-V2X is the only V2X technology that complies with the 3GPP specifications. C-V2X Direct Communications by 3GPP in 2017 Established in Release 14, also known as PC5 or Sidelink.
Thanks to improvements in modulation and coding techniques, better receivers, and overall advancements in technology driven by LTE, the C-V2X has better performance than wireless technology based on IEEE 802.11p, including support for farther Communication distance (approximately 2x), better non-line-of-sight performance, enhanced reliability (lower packet error rate), higher capacity, and better congestion control in denser environments. C-V2X performance advantages In the empirical analysis, simulation, laboratory results and field test results are all reflected.
C-V2X also has a clear 5G evolution path and supports forward and backward compatibility. Specifically, Rel-14 C-V2X has a strong evolution path to C-V2X based on 5G new air interface, which can be supplemented by New features enhance Rel-14 while maintaining backward compatibility. Compared to Rel-14 for basic secure communication between vehicles, C-V2X based on 5G new air interface provides high throughput, wideband carrier support, ultra low latency With high reliability, it supports many advanced use cases for autopilot, such as sensor sharing, intention sharing, and 3D HD map updating.
At the commercial level, C-V2X technology is also poised to take off. With the use of the Qualcomm 9150 C-V2X chipset or other competitive solutions, the C-V2X is expected to be produced in automobiles by volume as early as 2019. More importantly, , C-V2X has been supported by a wide range of automotive ecosystems, including the rapidly growing global industry organization - 5G Automotive Alliance. The organization aims to support the development of C-V2X and currently has more than 80 members, including leading automotive manufacturing. Suppliers, Tier 1 suppliers, software developers, mobile operators, semiconductor companies, test equipment manufacturers, telecommunications providers, traffic signal providers and road operators.
In addition, C-V2X leverages the defined upper-layer protocols of the automotive industry, including organizations such as the American Society of Automotive Engineers (SAE) and the European Telecommunications Standards Institute (ETSI), as well as the entire industry's investment in ITS software and applications over the years. This will accelerate the pace of C-V2X commercial deployment. The vast majority of new cars in the future are expected to embed cellular connectivity, while the C-V2X can be integrated in the basic cellular modems provided by the car, so compared with other V2X technologies C-V2X Deployment will be more cost-effective.
Qualcomm has the unique advantage of accelerating C-V2X development through commercial solutions and field trials
Over the years, Qualcomm has been committed to promoting the development of C-V2X technology and is preparing for deployment through cooperation with a wide range of ecosystems. Last September, Qualcomm released the first C-V2X commercial chipset solution - Qualcomm 9150 C-V2X chipset. The chipset is based on the 3GPP Rel-14 specification and is expected to be commercially sampled in the second half of 2018. During the same period, Qualcomm also introduced the C-V2X reference design, which includes integrated Global Navigation Satellite System (GNSS) functionality. 9150 C-V2X chipset and application processor and hardware security module running ITS V2X protocol stack.
At present, the Qualcomm 9150 C-V2X chipset solution has been favored by leading car manufacturers and automotive suppliers for supporting next-generation automotive and roadside infrastructure. Following Audi, Ford Motor, the flagship Citroën Group (PSA) and After SAIC announced its support for the Qualcomm 9150 C-V2X chipset and reference platform, more automotive ecosystem members expressed interest in adopting Qualcomm solutions and incorporating C-V2X technology into next-generation products, including Tier 1 LG Electronics, Continental Group, Valeo and Ficosa-Panasonic, etc., as well as cellular module manufacturers Sierra Wireless, Telit, Gemalto, Kaiyu Technology, Mobile Communications and ZTE, etc. Qualcomm also works with several V2X software stacks. Application providers and system integrators like Kleintech Co., Ltd. cooperate to accelerate the commercialization of C-V2X.
In addition, Qualcomm is working with numerous automakers and other automotive ecosystem members to collaborate on field verification of C-V2X in Germany, France, Korea, China, Japan and the United States. For example, Qualcomm has teamed up with AT&T, Ford Motors and Nokia. Announced the launch of the first US C-V2X trial in San Diego, which was supported by the San Diego Government Association (SANDAG), the California Transit Authority (Caltrans), Chula Vista, and McCain Inc. Qualcomm also participated in the European ConVeX Field testing (in cooperation with Audi), and 'Towards 5G' trial in France (in cooperation with PSA).
From an industry perspective, Qualcomm’s deep accumulation of wireless technologies not only accelerates innovation in the mobile industry, but also leads automotive innovation through its extensive connected automotive technology portfolio. Qualcomm offers one of the industry’s most extensive portfolio of automotive technology portfolios. Including cellular modems, Wi-Fi and Bluetooth connectivity, RF front-ends, GNSS and high-precision positioning solutions, software and infotainment platforms. In the future, Qualcomm will continue to provide innovative technologies for automotive manufacturers and Tier 1 suppliers through Key technologies such as 5G, Gigabit LTE, C-V2X and low-power high-performance computing support the next phase of growth in the automotive industry.
