The Channel Width has an influence on the wireless speed. Note: If possible, don’t select the DFS channel.ģ) Channel Width. The channel selection works as auto mode by default, we recommend you to use the Spectrum Analysis to analyze the channel and choose an uncongested channel. In order to get maximum signal, normally we set the transmit power as the maximum value.Ģ) Channel. The higher the transmit power is, the farer the signal. So we can also change the wireless settings to optimize the speed.ġ) Transmit Power. In order to get a better performance, we can refer to FAQ1044 to align the CPE.īesides the installation and alignment, the parameters of wireless settings also have an influence on the wireless throughput. Take this into account, when installing the devices, we should align the CPE devices. We can refer to FAQ907 to determine the height.ġ) When building a wireless link between two remote sites, we also need to take the Earth curvature into consideration to calculate the installation height.Ģ) Outdoor environment is complex, the weather like rain and wind will affect the link speed.Īll CPE devices have a radiation range, only in the radiation range we can receive the signal of the CPE device. To avoid these obstacles, we should install the CPE devices at a certain height. But if the link speed is extremely slow, here we can check the link speed based on installation and deployment, antenna alignment, wireless settings.ĬPE devices are often installed in outdoor environment, and there are many obstacles in these places. So the link speed will be lower than the maximum throughput and it is normal. In the real environment, many factors that will affect the link speed, like long-distance, wind, etc. Just as the following steps:ģ) Client Start to test the wireless speed.īecause of the wireless environment, the wireless throughput can up to 1/3 or 1/2 of the real link speed. Here we can use Speedtest ®tool to help us test the real wireless speed. There are some tools in CPE devices, such as Speedtest ®/Ping/Survey. In the picture above, the link speed is 65Mbps, which is lower than the maximum throughput, but it may be a reasonable value because there are many factors will affect the link speed, such as long-distance, wind, etc. In the following picture, we can see the link speed is 65Mbps in our test environment (The channel width is 10MHz.). Knowing that, we can check the link speed in the management page of CPE_AP. Take CPE510 as an example, when two CPE510 devices connect wirelessly in AP and Client mode, if we set the channel width as 10MHz, the link speed will be 72.2Mbps at most. We can see the relationship in the following table. In this part, what we need to check is the link speed and the real wireless speed.īefore checking the link speed, we need to know the maximum link speed is related to the channel width.
