LTE-V is a cellular IoV technology standard based on device to device (D2D) and existing LTE technologies. In the R&D phase, interoperability testing between terminals from different providers verifies connectivity and compliance with the standard.Testing the conformance of LTE-V terminals based on an authoritative third-party test platform is a crucial foundation for successful commercial deployment of LTE-V.

Rohde & Schwarz, a provider of conformance test equipment for mobile communications terminals, is also the world’s first provider of LTE-V test equipment: the R&S CMW500 equipped with the R&S CMW-KU514 LTE-V option in combination with the R&S SMBV100A GNSS simulator now supports LTE-V Mode 4 testing.

Huawei LTE-V2X terminals are based on the Huawei Balong 765 baseband IC. This chip has been specially designed for the new generation of IoV communications and can support UU interfaces (communication interfaces between terminals and base stations) and PC5 interfaces (short-distance direct communication between a vehicle and other devices). The application processor complies with 3GPP Release 14, and supports Mode 3 and Mode 4.

The successful interoperability test by Rohde & Schwarz and Huawei marks an important step for LTE-V products to meet international standards and, therefore, the commercial rollout of LTE-V. The test was performed in the wake of the World Internet of Things Convention (WIOTC) in Wuxi, China from September 15 to 18. There, Huawei LTE-V2X terminal-based solutions were successfully performed with a number of partners in the world’s largest LTE-V2X network covering main urban areas of Wuxi City and main roads of Wuxi New City.
