Huawei and Rohde & Schwarz have successfully performed LTE-V interoperability tests. The trials used the R&S CMW500 wideband radio communication tester, which utilized the embedded Huawei Balong 765 IC as an LTE-V UE. 

Overall, various Internet of Vehicles (IoV) communications scenarios were verified, based on 3GPP Release 14 Mode 4.

Using existing LTE technologies and mobile network infrastructure, LTE-V is the application of vehicular connectivity.

“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,” according to Rohde & Schwarz.

The successful tests edge LTE-V products closer toward meeting international standards, and ultimately the later goal of commercialization.

According to Rhode & Schwarz, the company is the “world’s first provider of LTE-V test equipment,” specifically LTE-V Mode 4 testing is now supported by the R&S CMW500 equipped with the R&S CMW-KU514 LTE-V option in combination with the R&S SMBV100 GNSS simulator.

The Huawei Balong 765 baseband IC serves as the base for the Huawei LTE-V2X terminals. Built to support IoV communications, the chip can support UU and PC5 interfaces, and the application processor supports Mode 3, Mode 4, and compiles with 3GPP Release 14.
