Rohde & Schwarz supports the demonstration of C-V2X “four-span” interconnection application

From August 30 to October 10, 2019, the laboratory of China Academy of Information and Communications Technology organized nearly 30 terminal manufacturers to participate in the 2019 C-V2X “Four-Span” Interconnection Application Demonstration Demonstration” activity. The LTE-V2X protocol (network layer, message layer and network security protocol) conformance test was carried out in the laboratory of the General Hospital in turn. This laboratory conformance test was organized by the C-V2X working group of the IMT2020 (5G) promotion group and other units in 2019. As part of the C-V2X “four-span” interconnection application demonstration activity, it has laid a solid foundation for the next field road experiments and demonstration activities. Neusoft’s Neusoft VeTest network layer, message layer and security layer conformance testing software combined with Luo The CMW500+SMBV platform of Germany & Schwarz formed the LTE-V2X protocol conformance test system, which undertook the protocol conformance test.

2019 C-V2X “Four-Span” Interconnection Co-sponsored by IMT-2020 (5G) Promotion Group C-V2X Working Group, China Intelligent Connected Vehicle Industry Innovation Alliance, China Automotive Engineering Society, and Shanghai International Automobile City (Group) Co., Ltd. The interoperability application demonstration event will be held in Shanghai Auto Expo Park from October 22 to 24. This “Cross-chip Module, Terminal, Vehicle, Safety”, referred to as “Four-span” event, will fully demonstrate C-V2X The mature achievements of the global industry chain will demonstrate the LTE-V2X communication security solution at the technical level, promote the establishment of a safe and reliable LTE-V2X large-scale application environment in the future, and further promote the commercialization of C-V2X in China.

As the world’s leading manufacturer of mobile communication test instruments, Rohde & Schwarz launched the CMW500+SMBV LTE-V2X test platform in October 2017, and successfully communicated with the world’s leading LTE-V2X chip manufacturers in 2018 It is also the only GCF-certified LTE-V2X protocol conformance test platform in the world that has passed the GCF certification test case (GCF test platform number TP92). The CMW500 mobile terminal comprehensive tester in this test platform system is the most widely used test platform in the world, covering 2G/3G/4G (including LTE-V2X) technical standards and wireless access technology standards such as Wi-Fi and Bluetooth. For LTE-V2X terminal certification, R&D and production, and scenario simulation testing. SMBV100A/B is a general-purpose digital RF signal generator, which can be used as a GNSS constellation simulator to simulate GPS/Beidou/Glonass/Galileo single constellation signals or multi-constellation signals, and provide synchronization signals in LTE-V testing.

In the system used in the laboratory test of this “four-span” activity, Rohde & Schwarz’s CMW500 + SMBV LTE-V2X test platform mainly provides LTE-V2X PC5 physical layer and access that meet 3GPP Rel.14 Layer simulation; Neusoft’s Neusoft VeTest test software mainly provides LTE-V2X network layer, message layer and security layer protocol conformance tests that meet Chinese standards, with a total of 91 test cases. The lab testing of this “four-span” event marks an important step forward for product certification testing required in future LTE-V2X commercialization.
