Google LLC 1600 Amphitheatre Parkway Mountain View, CA 94043 650 253-0000 main Google.com Federal Communications Commission 7435 Oakland Mills Road Columbia MD 21046 March 28, 2026 Subject: Request for Confidentiality FCC ID: A4RGBC0H, A4RG4HCD To Whom It May Concern: Pursuant to the provisions of Sections 0.457 and 0.459 of the Commission’s rules (47 C.F.R. §§ 0.457, 0.459), we request that the Commission withhold the following attachments as confidential documents from public disclosure indefinitely. ● Schematic Diagram ● Block Diagram ● Theory of Operation (Operational and Technical Descriptions) ● Tune Up Procedure In support of this request, we provide the following information: 1. Identification of the specific information for which confidential treatment is sought (§ 0.459(b)(1)): We request that all of the information contained in the above-referenced exhibits to the certification application be withheld from routine public disclosure. 2. Identification of the Commission proceeding in which the information was submitted or a description of the circumstances giving rise to the submission (§ 0.459(b)(2)): The material is being submitted in connection with our certification application for the above-captioned FCC ID. 3. Explanation of the degree to which the information is commercial, or financial or contains a trade secret or is privileged (§ 0.459(b)(3)): The market for the technology that is the subject of the certification application is highly competitive, with numerous companies competing for the business of potential customers. Were competitors to become aware of the facts set forth in the above-referenced exhibits to the application at this time, it could have an adverse impact on our competitive standing and deprive us of the marketplace benefit we otherwise might achieve by virtue of having the product available before other competitors. If any of the information for which confidential treatment is sought was made publicly available, competitors could reasonably determine the scope and status of our activities. 4. Explanation of the degree to which the information concerns a service that is competitive (§ 0.459(b)(4)): The technology that is the subject of the certification application is subject to intense competition from other manufacturers and service providers that are developing competing services and technology. 5. Explanation of how disclosure of the information could result in substantial competitive harm (§ 0.459(b)(5)): As noted above, were our competitors to become aware of the facts set forth in the above-referenced exhibits to the application, it could have an adverse impact on our competitive standing and deprive us of the marketplace benefit we otherwise would achieve by virtue of having the product available before other providers. 6. Identification of any measures taken by the requesting party to prevent unauthorized disclosure (§ 0.459(b)(6)): The information contained in the above-referenced exhibits to the certification application has been strictly controlled by us, with distribution limited to internal use only and for the specific purpose of conducting research, development, and testing of the technology. 7. Identification of whether the information is available to the public and the extent of any previous disclosures of the information to any third parties (§ 0.459(b)(7)): The information that we request be maintained as confidential is not available publicly. The information has been protected and kept confidential by limiting external contacts to privileged and confidential communications. 8. Justification of the period during which the submitting party asserts that material should not be available for public disclosure (§ 0.459(b)(8)): Given the competitive nature of the marketplace, any disclosure that we have developed the technology discussed in the above-referenced exhibits to the certification application would harm our competitive position. The information subject to this request for confidentiality should not be made available for public disclosure at any time. In addition, pursuant to Public Notice DA 04-1705, and in order to comply with the marketing regulations in 47 C.F.R. §2.803 and the importation rules in 47 C.F.R. §2.1204 while ensuring that business-sensitive information remains confidential until the actual marketing of newly authorized devices, we also request that the Commission grant temporary confidential treatment and not release the following attachments for routine public disclosure until 180 days after the grant date. ● External Photos ● Internal Photos ● Test Setup Photos ● User Manual It is our understanding that test measurement reports and correspondence during the certification review process cannot be granted confidential treatment, and such information will be available for public review once the grant of equipment authorization is issued.

Introduction Section FCC ID: A4RGBC0H (Parent Device) and FCC ID: A4RG4HCD (Variant Device) use the same identical internal printed circuit board layouts, while the variant model mmWave radio and antenna module are depopulated, details are available in the operational description. Based on their similarity, the FCC Part 15C (equipment class: DXX, DSS, DTS), Part 15E (equipment class: NII, 6CD, 6VL), Part 15F (equipment class: UWB), and FCC Part 22, 24, 25, 27, 90, 96 (equipment class: PCE, CBE, TNB) reuse the original model’s result and do spot-check. The spot check data in this report is used to justify the data reuse following FCC KDB 484596 D01 Referencing Test Data v03. The applicant should take full responsibility that the test data as referenced in this report represent compliance for this FCC ID: A4RG4HCD TEL: 886-3-327-0868 Page Number : 5 of 16 FAX: 886-3-327-0855 Issue Date : May. 18, 2026 Report Template No.: BU5-FR15CBT4.0 Version 2.4 Report Version : 06 FCC RADIO TEST REPORT Report No. : 5N0805-01 2. Model Difference Information A4RGBC0H and A4RG4HCD use the identical internal printed circuit board layout, and the difference in the components population: • A4RG4HCD: 5GNR FR2 mmWave related components are depopulated. • A4RG4HCD: 5GNR FR1 n79 related components are populated but SW is disabled in US. The supported GSM/WCDMA/LTE bands are all identical between A4RGBC0H and A4RG4HCD. The supported NR FR1 band comparison table is listed as following NR Band A4RGBC0H A4RG4HCD Same n2, n5, n7, n12, n14, n25, n26, n30, n66, n71 n38, n41 PC1.5, n77 PC1.5, n78 PC1.5 n2, n5, n7, n12, n14, n25, n26, n30, n66, n71 n38, n41 PC1.5, n77 PC1.5, n78 PC1.5 Diff. n48, n70 - The detail of similarity and difference is illustrated in the operational description, and based on the information spot check on conducted power, ERP/EIRP and radiated spurious emission was performed to ensure compliance.

Spot Check Verification Data Section Conducted power test and radiated spurious emission test configurations were selected from the worst cases identified in the parent model and tested to demonstrate the test data from original model remains representative for the variant model. Based on the RF parameter is still identical so the EBW from original model remains representative for the variant model. Summary for power and RSE spot check for each FCC rule part is listed as below: Test Item Mode Item A4RGBC0H Parent Worst Result A4RG4HCD Variant Check Result Difference (dB) Conducted Power ERP/EIRP (dBm) WWAN GPRS 850 Class 8 CH189 Power 32.58 32.76 -0.18 Antenna gain (dBi) -2.7 ERP 27.73 30.06 -0.18 WWAN GPRS 1900 Class 8 CH661 Power 29.59 29.57 0.…
