Quectel Wireless Solutions Company Limited Building 5, Shanghai Business Park Phase III (Area B), No.1016 Tianlin Road, Minhang District, Shanghai, China 200233 Request for Modular/Limited Modular Approval Date: 2022.01.13 Subject: Manufacturer’s Declaration for ☒ - Modular Approval ☐ - Split Modular Approval ☐ - Limited Modular Approval ☐ - Limited Split Modular Approval Confidentiality Request for: XMR2021EC25AFDL 8 Basic Requirements – FCC Part 15.212(a)(1) For Items Marked “NO(*)”, the Limited Module Description Must be Filled Out on the Following Pages Modular Approval Requirement Requirement Met 1. The modular transmitter must have its own RF shielding. This is intended to ensure that the module does not have to rely upon the shielding provided by the device into which it is installed in order for all modular transmitter emissions to comply with FCC limits. It is also intended to prevent coupling between the RF circuitry of the module and any wires or circuits in the device into which the module is installed. Such coupling may result in non-compliant operation. The physical crystal and tuning capacitors may be located external to the shielded radio elements. 15.212(a)(1)(i) ☒ - YES ☐ - NO(*) Details: <example – The module contains a metal shield which covers all RF components and circuitry. The shield is located on the top of the board next to antenna connector> 2. The modular transmitter must have buffered modulation/data inputs (if such inputs are provided) to ensure that the module will comply with FCC requirements under conditions of excessive data rates or over-modulation. 15.212(a)(1)(ii) ☒ - YES ☐ - NO(*) Details: <example – Data to the modulation circuit is buffered as described in the operational description provided with the application> 3. The modular transmitter must have its own power supply regulation on the module. This is intended to ensure that the module will comply with FCC requirements regardless of the design of the power supplying circuitry in the device into which the module is installed. 15.212(a)(1)(iii) ☒ - YES ☐ - NO(*) Details: <example – The module contains its own power supply regulation. Please refer to schematic filed with this application> 4. The modular transmitter must comply with the antenna and transmission system requirements of §§ 15.203, 15.204(b), 15.204(c), 15.212(a), and 2.929(b). 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 § 15.203 is not applicable to modules but can apply to limited modular approvals under paragraph 15.212(b). 15.212(a)(1)(iv) ☒ - YES ☐ - NO(*) Details: <example – The module connects to its antenna using an UFL connector which is considered a non- standard connector. A list of antennas tested and approved with this device may be found in users manual provided with the application> 5. The modular transmitter must be tested in a stand-alone configuration, i.e., the module must not be inside another device during testing. This is intended to demonstrate that the module is capable of complying with Part 15 emission limits regardless of the device into which it is eventually installed. Unless the transmitter module will be battery powered, it must comply with the AC line conducted requirements found in Section 15.207. AC or DC power lines and data input/output lines connected to the module must not contain ferrites, unless they will be marketed with the module (see Section 15.27(a)). The length of these lines shall be length typical of actual use or, if that length is unknown, at least 10 centimeters to insure that there is no coupling between the case of the module and supporting equipment. Any accessories, peripherals, or support equipment connected to the module during testing shall be unmodified or commercially available (see Section 15.31(i)). 15.212(a)(1)(v) ☒ - YES ☐ - NO(*) Details: <example – The module was tested stand-alone as shown in test setup photographs filed with this application> 070920-02b Modular Approval Requirement Requirement Met 6. The modular transmitter must be labeled with its own FCC ID number, or use an electron display (see KDB Publication 784748). If using a permanently affixed label with its own FCC ID number, 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: XMR2021EC25AFDL” or “Contains FCC ID: XMR2021EC25AFDL” 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 requirement. In the latter case, a copy of these instructions must be included in the application for equipment authorization. If the modular transmitter uses an electronic display of the FCC identification number, the information must be readily accessible and visible on the modular transmitter or on the device in which it is installed. If the module is installed inside another device, then the outside of the device into which the module is installed must display a label referring to the enclosed module. This exterior label can use wording such as the following: “Contains FCC certified transmitter module(s).” Any similar wording that expresses the same meaning may be used. The user manual must include instructions on how to access the electronic display. A copy of these instructions must be included in the application for equipment authorization. 15.212(a)(1)(vi) ☒ - YES ☐ - NO(*) Details: <example – There is a label on the module as shown in the labeling exhibit filed with this application.

Quectel Wireless Solutions Company Limited Building 5, Shanghai Business Park Phase III (Area B), No.1016 Tianlin Road, Minhang District, Shanghai, China 200233 Test Data Reuse Letter This application is intended to reuse previous test data (from EC25-AF, FCC ID: XMR201808EC25AF 2018/08/03 initial application), due to the fact that the two models of products are hardware-wise identical and only the following changes have been made: EC25- AFDL ( FCC I D: X M R20 21EC25AFDL) is the variant of certified EC25 - AF module EC25-AF and EC25-AFDL are all LTE modules. the differences are just as follow: 1. The platform of EC25-AF is MDM9207, EC25-AFDL is MDM9307. They use the series chipset. For details, you can check Qualcomm's statement. 2. EC25-AF supports LTE and WCDMA. EC25-AFDL supports LTE only. The main change of software is disabled WCDMA and voice part. 3. The PA of EC25-AF is QM56020, EC25-AFDL is QM56030 Main RF components changes as follow table The position of the different components in the PCB is shown in the follow picture So, we have performed spot checks on the following items to verify that if any unexpected RF conducted power or emission changes can be noted. The test results show that all spot check data are within the instrument measurement uncertainty and data reuse is justifiable. Quectel Wireless Solutions Company Limited Building 5, Shanghai Business Park Phase III (Area B), No.1016 Tianlin Road, Minhang District, Shanghai, China 200233 Verification test items with 1 sample: ⚫ Conducted Power ⚫ Conducted, Radiated Spurious Emission Test (choose worse case) For the test result please refers to included exhibit “Test Reports.pdf” for detail Reuse data test items ⚫ Conducted Power / EIRP/ ERP / PAPR / OBW / Modulation characteristics / Frequency stability ⚫ Band edge Also, both the referenced application and this new application are all subject to the same ISED rule and there is no new rule update for related rules. Accordingly, we believe that the reuse data from previous certified filing is justifiable. Thank you for your attention and please feel free to contact us, if you should have any questions.
