Performance

Next, I actually examined the performance of Wi-Fi 6E. In some overseas countries and regions, Wi-Fi 6E is already available and APs are in circulation. Here, using such AP, we will introduce how much performance the wireless LAN in the 6GHz band has.

In the United States, frequencies from 5925M to 7125MHz can be used for wireless LAN, and some compatible APs are on sale. Among them, the aforementioned GT-AXE11000 is used in this experiment (Fig.2-1). The GT-AXE11000 is an indoor AP that supports 2.4G/5G/6GHz tri-band. The Wi-Fi Alliance has obtained "Wi-Fi CERTIFIED 6" and "6 GHz Spectrum Capabilities" certification.

As a Wi-Fi client compatible with the 6GHz band, we used Spirent Communications' "Spirent TestCenter C50 Appliance Wi-Fi 6E Compatible High Radio Model" (hereafter, Spirent TestCenter C50). Spirent TestCenter is a commonly used measuring instrument in the telecommunications industry. Measure router performance and scalability. In the model used this time, AP can be evaluated efficiently by emulating a data transmission server with a wired LAN port and a Wi-Fi client with a wireless LAN port.

Because the use of wireless LAN in the 6GHz band is not approved in Japan, the AP to be measured was installed in a shield box (anechoic box) to block it from the outside (Fig.2-2). Spirent TestCenter C50 and the shield box were connected with LAN and coaxial cables, and the power of the AP was turned off when opening and closing the shield box.
