工业网关WiFi性能测试方法

Test Method for WiFi Performance of Industrial Gateway

5G工业网关可作为连接5G基站与WiFi无线设备的桥梁,对其性能进行测试是保证系统稳定通信的关键。然而,当前对工业网关WiFi性能测试方法的研究较少。吞吐量是衡量WiFi性能的重要指标,针对吞吐量与覆盖距离、多用户并发吞吐量,分别设计单用户测试系统和多用户测试系统,研究测试方法并完成工业网关样品测试,最后对测试结果进行分析。所提出的测试方法采用程控衰减器控制衰减模拟增量距离,通过全电波暗室在实验室实现性能测试,测试环境可控性强、可重复性高,对数据接入类终端的WiFi性能测试具有借鉴意义。

5G industrial gateways can be used as a bridge connecting 5G base stations and WiFi wireless devices,and testing their performance,is the key to ensure stable communication of the system.However,there is currently less research into WiFi performance testing methods for industrial gateways.Throughput is an important index to measure WiFi performance.The single-user test system and multi-user test system are designed according to the throughput and coverage distance and multi-user concurrent throughput,then the industrial gateway is tested and the test results are analyzed.The test method proposed in this paper uses programmable attenuators to simulate incremental distance,and realizes the performance test in the laboratory through the anechoic chamber,which has the characteristics of high controllability and repeatability of the test environment,it can be used for reference to test the WiFi performance of data access terminals.
