Mark –
The wireless portion falls under 15 Subpart C section 15.247 (I assume its 802.11bgn) and possibly under 15 E if it supports 802.11an. It also falls under the rule parts for a digital device. If its a device for home use that can connect to a PC (which seems likely) then it is considered a Class B PC peripheral and, as such, subject to either certification or Declaration of Conformity. You know have the choice to either cover the digital device certification at the same time you get the wireless portion certified as a composite device or you certify the wireless device and use the Declaration of Conformity procedures for the digital device. I know it seems odd that you would treat the complete product as two separate devices. Perhaps it is better to say that you evaluate the product under two separate rule parts. All emissions you can identify as being from the wireless circuitry need to comply with the wireless rules and everything else needs to comply with the digital device rules.

One of our test labs insist (they claim this comes from TCB) what we should treat wireless router/gateway as composite device, meaning Intentional radiator (wireless portion) done through certification and Ethernet/cable ports are treated as PC's peripheral, hence require DoC and logo on the label. In my opinion it does not make sense to treat wireless router/gateway as composite device. It is standalone device which performs multiple functions, but I do not see how can you treat Eth or cable port as separate device. Would be interested to hear some opinions.
