Well... most TVs already have a WiFi/BT chipset for stuff like advertisements or, especially with Apple, high-bandwidth video streaming. There is already a radio module present, but (IIRC) you don't have to disclose what exactly that module is capable of.

You definitely are required to disclose what frequencies are used and at what power.

Uhh yes you absolutely do need to disclose exactly what each is capable of. Each radio must itself be approved by the FCC and documented
