摘　　要：本文应用信道仿真仪、USB无线网卡、射频器件、屏蔽箱、Chariot网络性能测试软件和Network Stummer无线网络监测软件,设计了一套无线局域网设备传输性能测试系统,对比测试了无线网卡在是否运行标准信道模型、自定义信道模型状态下的性能,分析改变信道参数对无线网卡性能的影响。测试结果表明,标准信道模型下的吞吐量及传输速率较无信道模型状态明显下降;信道模型中,速度变化对无线网卡性能的影响较大。This paper uses channel simulator,USB wireless network card,radio frequency device,shielding box,Chariot network performance test software and Network Stummer wireless network monitoring software to design a set of WLAN equipment transmission performance test system,and comparatively test the performance of the wireless network card in whether the standard channel model and the custom channel model are running,and analyze the impact of changing the channel parameters on the performance of the wireless network card.The test results show that the throughput and transmission rate under the standard channel model are significantly lower than those under the non-channel model;in the channel model,speed changes have a greater impact on the performance of the wireless network card.
