This document serves as a declaration from Mengzhiyuan Technology Group Co., LTD regarding the capabilities of their equipment concerning WIFI channels 12 and 13. The declaration outlines several possible scenarios, including that the product hardware does not have the capability to operate on these channels, or that the channels are disabled via software and inaccessible to the user. Another possibility is that the hardware can operate on these channels, but all operated channels can't be changed in the RF parameter via software, and all channels comply with FCC Part 15.247.
The document also addresses compliance with KDB 594280 D01 v02r01, stating that the product hardware has the capability to operate on WiFi Channel 12 and 13, and meets the requirements of this standard. It further explains that the device operates in a mode compliant with U.S. requirements by default, and may use geo-location data to determine if it is operating outside the U.S., adjusting its power accordingly. This geo-location data may be derived from various sources, including GNSS sensors, Mobile Country Code (MCC), and adjacent access points.
