CoreStar Co., Ltd To: Federal Communication Commission Date: 2026/5/22 Office of Engineering and Technology RE: Modular Approval Application for FCC ID: 2ANCG-M8800DU6 Dear Sir / Madam, The information regarding the modular approval for FCC ID： 2ANCG-M8800DU6 is detailed below. Requirement of FCC KDB996369 – Modular Approval Requirement Comply（Y/N） 1. The modular transmitter must have its own RF shielding. Y - The EUT provides the RF shielding. See EUT photo. 2. The modular transmitter must have buffered modulation/data inputs (if such inputs are provided) to ensure that the module will comply with Part 15 requirements under conditions of excessive data rates or over-modulation. Y - The EUT has its buffered modulation. Please see the Schematic Diagram. 3. The modular transmitter must have its own power supply regulation. Y - The EUT has its own power supply regulation, please see the Schematic Diagram. 4. The modular transmitter must comply with the antenna and transmission system requirements of Sections 15.203, 15.204(b) and 15.204(c). The antenna must either be permanently attached or employ a “unique” antenna coupler (at all connections between the module and the antenna, including the cable). The “professional installation” provision of Section 15.203 is not applicable to modules but can apply to limited modular approvals under paragraph (b) of this section. Y - The EUT meets the FCC antenna requirements; permanently attached and photo of antenna are shown in the test report. 5. The modular transmitter must be tested in a stand‐alone configuration, i.e., the module must not be inside another device during testing. Y - The EUT was tested with a test cable, see test report and setup photo 6. The modular transmitter must be labelled with its own FCC ID number, and, if the FCC ID is not visible when the module is installed inside another device, then the outside of the device into which the module is installed must also display a label referring to the enclosed module. This exterior label can use wording such as the following: “Contains Transmitter Module FCC ID: 2ANCG- M8800DU6” or “Contains FCC ID: 2ANCG-M8800DU6” Any similar wording that expresses the same meaning may be used. The Grantee may either provide such a label, an example of which must be included in the application for equipment authorization, or, must provide adequate instructions along with the module which explain this Y - Please see exhibition label sample for the FCC ID of this module. And also in the exhibition User’s manual, there are instructions to the OEM on how to label the end product. CoreStar Co., Ltd requirement. In the latter case, a copy of these instructions must be included in the application for equipment authorization. 7. The modular transmitter must comply with any specific rule or operating requirements applicable to the transmitter and the manufacturer must provide adequate instructions along with the module to explain any such requirements. A copy of these instructions must be included in the application for equipment authorization. Y - The EUT is compliant with all applicable FCC rules. Details instructions for maintaining compliance are in the User Manual. 8. The modular transmitter must comply with any applicable RF exposure requirements. For example, FCC Rules in Sections 2.1091, 2.1093 and specific Sections of Part 15, including 15.319(i), 15.407(f), 15.253(f) and 15.255(g), require that Unlicensed PCS, UNII and millimeter wave devices perform routine environmental evaluation for RF Exposure to demonstrate compliance. In addition, spread spectrum transmitters operating under Section 15.247 are required to address RF Exposure compliance in accordance with Section 15.247(b)(4). Y - The EUT complies with RF exposure requirement. Sincerely, Name (Printed): Daniel Lin Title: RD Project Manager Signature: On behalf of Company: CoreStar Co., Ltd
