Where can I find construction details and test data for wireless LAN products?

Wireless LAN products sold in the U.S. must be certified by the Federal Communications Commission (FCC). The certification process requires that the manufacturer submit detailed information about a product including external and internal construction detail photos and test reports.

The FCC website has search tools that can find a product by its FCC ID (usually found on the serial number label of the product) and also find manufacturers' three-character 'Grantee Code' that is helpful for general product searches.
