TR-398 Issue 2 & Issue 3 WiFi Testing with LANforge

Broadband forum的TR-398 WiFi Performance test plan提供了一套全面的测试，可验证住宅和小型办公室室内环境中部署的WiFi无线接入点(AP)的性能，包含网络性能、吞吐量、连接稳定度、公平时间调度（Airtime Fairness）和长期稳定性，综合性的测试项目复盖绝大部分的测试领域。TR-398 Issue 2增加新测试项目，包含双频吞吐量(Dual Band Throughput)、双向吞吐量(Bi-directional Throughput) 以及802.11ax-高峰性能表现(Peak performance)和频道自动选择测试(Automatic Channel Selection)，TR-398 Issue 2可适用于所有 802.11ax以及旧有的802.11n/ac模式。而TR-398 Issue 3相较于TR-398 Issue 1 & TR-398 Issue 2包含了新的测试应用，TR-398 Issue 3中的新测试应用包含：负载下的延迟(Latency-under-Load)、服务质量(QoS)、多频段吞吐量(Multi-Band throughput)、Mesh测试、并支持6E以及测试平台的自动校准，此自动化程序可让用户自定义测试内容，包含执行和通过/不通过指针。(Broadband Forum的 TR-398 Issue 3 文档仍在进行中。)

此测试解决方案可提供设备供应商，在进行部署WiFi AP前对实验室中的AP进行确认，以供设备製造商在AP的开发过程中进行测试。

Candela Technologies提供自动化的TR-398测试系统，以合理的价格和解决方案提供所有必需的测试硬件，包括多个无线终端模拟器、流量产生器、RF外箱、控转盘、可编程衰减器和全自动测试软件以及PASS / FAIL结果报告，简单的操作即可满足测试且可获取All in one的测试报告。
