General: iPerf & Speedtest LimitationsNetAlly tools are 1GB and 10GB testers, depending on the model, at Layers 1 & 2. They verify you can link at the applicable speed, meaning the switch and cabling is ok. Our tools are not 1G/10G software on top of the TCP/IP stack performance testers. We do not support L3 hardware packet reflection. Keeping this in mind, testing is limited to around 500 Mbps for most of the testers like the EtherScope nXG, LinkRunner 10G, AirCheck G2/G3. The LinkRunner G2 is limited to about 200 Mbps.翻译:我们的工具不是1G/10G 的TCP/IP协议性能测试仪软件。我们不支持L3层硬件数据包反射。记住这一点,对于大多数测试人员,如EtherScope nXG、LinkRunner 10G、AirCheck G2/G3,测试限制在500 Mbps左右。LinkRunner G2被限制为大约200 Mbps。...
您是否为高速互联网花了很多钱而没有达到预期? 您的 无线网络是否正常工作,而现在突然陷入了无线网速慢的问题? 选择正确的无线网信道可以显着提高无线网覆盖范围和性能。在2.4 GHz频段中,只有1、6、11三个信道是不重叠的。从这几个信道中选择一个或多个,是正确设置网络的重要部分。目前,许多无线路由器在初始设置时自动为您选择通道,这取决于您的无线环境,但可能会导致无线网速慢并有干扰。本文将描述您正在处理的干扰问题,并引导您选择正确信道,这样您就可以理解为什么应该在信道1、6和11之间进行选择。无线网受干扰的三个主要原因太多的无线设备在同一个信道上工作之前,同信道干扰并不是一个大问题。另一方面,邻接信道干扰是问题所在,信道选择变得至关重要。幸运的是,这些与信道相关的干扰可以通过为你的网络选择合适的无线网信道来减少或消除。使用像inSSIDer这样的频谱分析仪可以让你看到无线环境,所以你可以选择正确的信道或减轻无线干扰,最终提高你的2.4 GHz无线网络性能。非重叠信道2.4 GHz频段中每个信道的带宽为20 MHz。信道中心被5 MHz隔开,整个频谱只有100 MHz宽。这意味着11个通道必须挤进可用的100MHz,并最终实现重叠。在2.4 GHz频段中,2、3、4、5、7、8、9、10信道均有明显重叠,造成邻接信道干扰。但是,信道1、6和11在2.4GHz频段上相距很远,因此它们的信道中心之间有足够的空间,不会重叠。虽然选择信道1、6或11意味着你必须与其他网络共享信道(同信道干扰),但这比处理所有其他频道发生的邻接频道干扰要好得多。有了上面的信息,在不使用任何软件的情况下,您已经将选择范围缩小到三个通道(1、6和11)!但是这并不意味着相邻的网络没有使用非标准的信道。这就是AirCheck g2可以提供帮助的地方。使用AirCheck g2,你可以将在AirCheck g2范围内的每个网络可视化,这样你就可以确定你的选择。有关信道干扰类型的更多信息,请查看我们的视频教程。使用AirCheck g2的好处是,你现在可以看到是什么导致了你的无线网出现+问题,并快速修复它。AirCheck g2会自动为你推荐最佳的信道,你不需要成为一个无线网专家就可以使用它。只需启动AirCheck g2,然后开始计算每个频道上活跃的网络数量。第一步是点击“信道”标题来对信道进行排序。你要找的是拥有最少网络的信道(即1、6和11)。请注意,在上图中,名为“bba”的网络在第9信道运行,但在第6信道和第11信道重叠。信道1上只有一个活动网络,而且信号强度很低。如果您在选择哪个信道最适合作为新的接入点,那么信道1拥有最少的网络数量,并且没有任何部分重叠的网络。在本例中,选择的最佳信道是信道1....
If you have access to YouTube, you can click here to watch a video of this new feature in action. In data centers where the shield is typically grounded at both ends, ANY wire map tester will report the shield as connected, even if it is not. That's because the shield test is a simple DC Resistance measurement. If the shield is open, it will find the remote unit using the building ground (earth).The DSX CableAnalyzer offers a unique solution to this problem. It ties the four pairs together and then sends a differential signal down the cable treating the shield as the second conductor. This allows the DSX CableAnalyzer to view the shield in the time domain. So even if the patch panels are grounded, it will report the shield open, if indeed it is open you would see:And since it is using time domain techniques, the distance to the open is given. In this example, we can see the patch panel at the near end is the issue.The scenario above occurs when the technician grounds the connector on the non conductive side of the cable shield. The result is degraded Alien Crosstalk performance. Since users are told that shielded cabling systems do not need to be tested for Alien Crosstalk, one wonders how wide spread this issue is and whether users are getting the performance they paid for.附加信息If you only use the drain wire to connect the shield and that drain wire is greater than approx. 2 inches (5 cm), the DSX CableAnalyzer may report the shield as open. This is by design. Such a termination acts as an open circuit at the frequencies we are talking about here....
