Research on LTE-V2X Outfield Expressway Performance Testing Method in the 5.9GHz Band

As an end-to-end wireless communication channel for intelligent transportation systems, LTE-V2X requires efficient allocation of spectrum resources for its scientific and effective operation. In research of the Internet of Vehicles, frequency and compatibility verification of LTE-V2X systems operating in the 5.9GHz band is a hot topic of this research. The outfield expressway performance testing is a branch of this research. Whether the LTE-V2X system's communication performance in the expressway meets the technical requirements is the prerequisite for the promotion and application of the LTE-V2X system in China. Aiming at this problem, this paper proposes a LTE-V2X outfield performance testing method in the 5.9GHz frequency band. In the testing environment of straight and curved expressways , the V2V / V2I link communication performance is tested separately. Finally, the testing data is analyzed to obtain static and dynamic testing results on the expressway.
