SMSC does not certify all module variants for all countries. Please see above table for those module versions for which
certain certifications have already been done.
Please contact your SMSC sales office for the latest information about which modules are certified for which countries, and
arranging for additional certification for your chosen module if needed. Any additional certifications will need to be paid for by
the customer.
Product manufacturers are responsible for the end product certification.
SMSC can help manufacturers to prepare for the WiFi Alliance tests by providing an example test plan and the required
commands to enable special test modes. Please contact your SMSC sales office about WiFi Alliance logo certification
assistance.
The CX module has received Limited Module Approval (LMA) from FCC. This is because the CX module does not have a
built-in +1.9V regulator circuit. SMSC recommends that customers follow the +1.9V supply voltage requirements given in
this data sheet, and follow the +1.9V power supply design given in “CX Module Power Supply_V1.1.pdf” document or later
version. If the power supply recommendations are followed, then customers will not need to go through formal certification of
the product for WiFi related RF behavior for FCC. It is the product manufacturers responsibility to make sure that the power
supply recommendations are followed, and that the RF behavior meets the certification requirements when the module is
installed in the final product.
Please check the SMSC/BridgeCo Customer Portal at
https://portal.bridgeco.net/ for documents about WiFi certification and
recommended interfacing and power supply schematics.
