We have a customer whose product is based on a BCM4390 Wi-Fi SoC running WICED 3.1.2. They are setting the country code to WICED_COUNTRY_WORLD_WIDE_XX, and shipping units to the United States. They have questions about meeting regulatory requirements in the United States.
According to their testing, the find that with this country code, they are able to join Access points advertising on channels 12 and 13. Will that behaviour invalidate certification in the United States for their product?
Also, what is the maximum output power of this SoC when transmitting data?
