2022年8月25日，FCC發布Zui新公告，即日起所有FCC Part 15的FCC ID申請資料均需提供天線信息或者天線報告，至少要包含Zui大增益、天線方向圖、用于識別設備內部天線的圖片或繪制圖等信息，報告中將不再接受客戶宣稱的天線增益的說法。所以沒有上網的各類WiFi, Bluetooth, Zigbee, Lora, UWB等產品目前上網均需提供符合要求的天線報告。

此外，除了Part 15標準以外：任何需要測試場強的標準，例如常見的FCC part 15.225, 15.227, 15.229, 15.231, 15.239, 15.249等標準，雖然并不需要提供天線信息或者天線報告，但需要體現天線的照片、尺寸等信息在報告里面或者產品照片上。

特別說明的是：由于一些商業保密需求，有必要剔除相關保密的信息，如設計原理等可以從報告中刪除，或者整個天線報告可以進行保密。但天線增益的信息是公開的，如果天線報告只包含Zui大增益、天線方向圖、用于識別設備內部天線的圖片或繪制圖，FCC不被視為可保密的信息。

URGENT CLARIFICATION - FCC Area of Concern-Antenna Gain Information

Please see the updated notice regarding Antenna Gain Information

Any applications granted after August 25, 2022 that do not contain the proper antenna information will be dismissed.

This email is to bring to your attention that while the FCC has been advising test labs and TCBs to make sure part 15 applications includes antenna gain data sheets and/or test reports, it is evident by recent audits that this information is being omitted.

We are still finding reports that state, "antenna gain information is declared by the manufacturer", with no other supporting information. As we have re-iterated during the last TCB workshop, this statement will not suffice. All part 15 applications will need to show how the antenna gain was derived either from a manufacturer data sheet or a measurement. Where the gain of the antenna is inherently accounted for as a result of the measurement, such as field strength measurements on a part 15.249 or 15.231 device, so the gain does not necessarily need to be verified.  However, enough information regarding the construction of the antenna shall be provided. Such information maybe photographs, length of wire antenna etc.

The antenna gain information shall be made public (not confidential).  Any proprietary information such as construction maybe stripped from the gain information report and held confidential. The main antenna information we require is the maximum gain of the antenna for the band of operation. This information must be provided as a data sheet or a measurement report.
