FCC Issued Notice of Proposed Rulemaking
on mmWave (and higher) spectrum

The FCC issued a long-anticipated Notice of Proposed Rulemaking under ET Docket 18-21 on February 28, 2018 and seeks "comment on proposed rules to permit licensed fixed point-to-point operations in a total of 102.2 gigahertz of spectrum; on making 15.2 gigahertz of spectrum available for unlicensed use; and on creating a new category of experimental licenses to increase opportunities for entities to develop new services and technologies from 95 GHz to 3 THz with no limits on geography or technology."

This is a broad NPRM with a lot of impact towards development of technologies and testing methods, truly pushing the state-of-the-art.

ACB is active with the mmWave Coalition, the TCB Council and American Council of Independent Laboratories on comments to this NPRM. We will likely see communications technologies that will extend into the hundreds of GHz, which will bear great impact on 5G and IoT applications into the next decade.

The comment period ends 30 days after the February 28 issue date.

Certification and Compliance Updates
Questions and Answers

1. UWB产品FCC认证时，需要测试的技术特性可以参考的要求是什么？

   Question: What technical characteristics must be measured to demonstrate ultra-wideband (UWB) device compliance to the applicable requirements specified in Part 15 Subpart F? view answer
   

2. 无线键盘作为附件的产品怎样进行SAR评估？

   Question: One of our clients has a wireless keyboard that tends to be used along with iPad, as an accessory. The product is a very low power device that must comply with FCC Part 15.249 rule. Kindly advise if a TCB can directly certify this project (w/o SAR evaluation) or this device is to consider SAR when it works along with iPad? view answer

4. KDB865664 D01中需要在报告中添加系统验证的结果。

Please note that the SAR System Validation data required by KDB865664)D01)3.3.1) is different than the SAR System Verification tests, which were correctly performed and included in the report. The System Validation test is more like an ISO/IEC 17025 requirement… please see Section 3.3.1 of the referenced KDB Publication, which states, in part, that ’’ a tabulated summary of the system validation status, according to the validation date(s), measurement frequencies, SAR probes, calibrated signal type(s) and tissue dielectric parameters, is required in the SAR report.” In the future, please begin to also include the SAR System Validation data, similar to that shown below, but specific to your own test equipment, in your SAR reports, as required. Detailed system validation results must be maintained by each test laboratory, which are normally not required for equipment approval. Only a tabulated summary of the system validation status, according to the validation date(s), measurement frequencies, SAR probes, calibrated signal type(s) and tissue dielectric parameters, is required in the SAR report. However, when questions arise or details are required due to probe conversion linearity or other measurement concerns, the relevant system validation results may be required in SAR reports to support the measurement results for equipment approval.
