WiFi性能测试方法及系统
技术领域
本发明涉及测试技术领域，尤其涉及一种WiFi性能测试方法及系统。
背景技术
目前，WiFi STA终端产品（Smart TV、mobile phone、Tablet等）层出不穷的出现在人们的视野中。而在这些产品流入市场前，如何有效地评估这些产品WiFi性能的可靠性和稳定性是非常重要的。
目前为止，在量产前，厂商一般首先会对产品的WiFi 模块做单独的硬件性能测试（根据WiFi或802.11的理论定义），比如基本参数、工作频率范围、发射功率、发射信号频谱、频率误差、EVM、杂散发射、接收灵敏度、接收最大输入信号电平、相邻信道抑制等，此测试为最基本的保证WiFi模块基础硬件性能合格的必备过程，一般module vendor或IC vendor都会对其做严格测试。然后会对产品做反映WiFi软硬件数据通信能力的无线吞吐量测试。因为WiFi模块本身的硬件量测不能反映整体的WiFi性能，WiFi模块的使用需要整体系统的加载配合，比如WiFi模块内部使用的固件、WiFi驱动、WiFi上层配置和应用。为了衡量出基于整个系统的WiFi使用性能，需要基于系统之上的一种测量方法、目前为止，一般通过利用Iperf、Ixchariot等模拟数据收发工具的吞吐量量测手段, 基于系统之上，贯穿WiFi软硬件层通道。图1为利用Iperf软件工具丶WiFi STA选取Smart TV为例的一个基本测试框架。Iperf client程序运行在与WiFi Router通过有线连接的PC上，Iperf server程序运行在WiFi STA端（附图为搭配有WiFi网卡的智能电视）。当需要对WiFi STA的接收性能做量测时，需要在WiFi STA端所在的操作系统中移植进匹配的iperf程序，然后以shell指令或者图形界面方式打开并且输入对应的参数继而开启服务器端监听进程，然后在PC端所在的操作系统同样移植匹配的iperf程序，并且以完全命令调用方式或者图形界面方式输入相关执行参数继而建立与服务器端监听进程的TCP连接然后持续发送数据，最终获得WiFi STA的最大数据接收速率。
