FCC关于提供天线增益信息的更新！

2022年8月25日，FCC发布最新公告，FCC part 15的FCC ID申请项目都需要提供天线规格信息， 如FCC part 15C（如: 15.247….）, FCC part 15D, 15E等标准需要提供天线的报告或者数据表技术规格书等，里面已经包含天线增益等信息，因而不再接受客户宣称的天线增益的说法。

这类标准除外： 产品测试场强的标准，例如常见的FCC part 15.225, 15.227, 15.229, 15.231, 15.239, 15.249等标准，不需要提供天线增益的信息。

需要留意的是由于一些商业保密需求，有必要剔除相关保密的信息，如天线结构或照片等可以从报告中删除并保密。

官方原文如下：

URGENT - FCC Area of Concern-Antenna Gain Information

The following urgent information has been provided by the FCC:

Any applications granted without the proper antenna information will be dismissed after 5 business days of this email. The TCBs can request to have the application put in an audit status to update the antenna information.

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 information, in terms of data sheets and/or test reports. This information is evident by recent audits confirming this information was 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, example such as a field strength measurement on a part 15.249 or 15.231 device. As a result, 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. 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..
