Does EVERY device with a wireless transceiver (e.g. Zigbee) need FCC approval?

I understand that if I make a device which has in it a wireless Zigbeetransceiver (or any active wireless transceiver), that I would needFCC approval.However, what if i made a little soapbox-shaped transceiver unit, andhave some wired serial connection (e.g. i2c, CAN, rs323), would I onlyneed FCC approval on that soapbox unit, regardless of what otherproducts I connect it to via serial wire?I guess its analogous to having a Linksys or Netgear wireless router.The devices that are connected to it don't have to be FCC-approved.Basically, I need to know if FCC fees will make Zigbeetransceiver-integrated embedded systems expensive than just using onecommon FCC-approved Zigbee unit, and wire it to my other products.
