14 Appendix A: Regulatory Approval

Gain Table for Individual Regulatory Region

The ATWINC3400-MR210CA module has received regulatory approvals for many regions in the world, namely United States/FCC, Canada/ISED, Europe/CE, Japan/MIC, Korea/KCC, Taiwan/NCC, and China/SRRC. The ATWINC3400-MR210UA module has received regulatory approvals for United States/FCC, Canada/ISED and Europe/CE.

The default firmware uses a common gain table that meets IEEE 802.11 specifications, and regulatory region limits for both ATWINC3400-MR210CA and ATWINC3400-MR210UA as noted above. In some cases, the output power is reduced by limits of regulatory region with stringent transmit power limits. To optimize performance, and if end products’ destination is known, the specific gain table for that region can be optionally embedded into the firmware.

The regulatory region certified gain table for individual regulatory region is available on ATWINC3400-MR210CA and ATWINC3400-MR210UA product page. Customers can update the gain table in firmware by following the instructions in section 6.
