2.3 Wi-Fi Regulatory Certification Gain Table

The Wi-Fi Certification Gain Table refers to the gain setting of the ATWINC3400A device that would allow it to be compliant to the specific regulatory region requirements such as FCC (USA), ISED (Canada), CE (Europe) and so on.

• The certification testing of the product for the relevant standard is done by external accredited test labs such as TuV, Compatible Electronics, etc.
• During certification, the Digital Gain value needs to be adjusted for compliance to the regulatory specifications.
• The final Wi-Fi Certification Gain Table must be determined after covering all of the different regulatory regions that the product is targeted for.
• In cases where multi-region compliance is desired with a single-product firmware, use the gain value with the minimum gain setting. For example, once the certification tables for FCC, ISED and CE are derived, and intended to serve all three regions, then the user needs to derive the final gain table by comparing each gain value for the given channel and data rate to choose the lower gain value for the selected channel and data rate. This has to be done for all of the channels and data rates in the gain table to derive the final Certification Gain Table.
• In cases where multi-region compliance is desired with a multiple-product firmware, the device can be loaded with a firmware specific to the intended destination (regulatory region), thereby ensuring that the maximum benefit can be achieved out of the regulatory limits of the intended destination.
