The Multi-Mode IoV Communication Performance Test and Verification in Closed Test Field

Based on the closed test field, three kinds of IoV communication network test platforms of 5G, EUHT, and LTE-V are constructed, and four kinds of test scenarios are designed, including the full-field performance test, the dynamic and static performance test, the V2I communication performance test, and the V2V communication performance test. Taking delay, packet delivery rate, and throughput as evaluation indicators, the performance of the above three communication networks in typical application scenarios such as different communication distances, different vehicle driving speeds, V2I communication uplink, downlink, and hybrid transmission, and end-to-end V2V communication is verified and comparatively analyzed in real-vehicle tests. The results show that all three networks can meet the requirements of vehicle-connected applications in general dynamic traffic environment, among which 5G has the best performance, EUHT is second, but in terms of deployment cost and difficulty, LTE-V has a greater advantage.
