Quectel Wireless Solutions Company Limited Request for Confidentiality Date: _2021/3/5_ Subject: Confidentiality Request for: _____ FCC ID: XMR2021SC200LEM ______ Pursuant to FCC 47 CRF 0.457(d) and 0.459 and IC RSP-100, Section 10, the applicant requests that a part of the subject FCC application be held confidential. Type of Confidentiality Requested Exhibit Short Term PermanentBlock Diagrams Short Term External Photos Short Term Permanent* 1 Internal Photos Short Term Permanent Operation Description/Theory of Operation Short Term Permanent Parts List & Placement/BOM Short Term Permanent Tune-Up Procedure Short Term Permanent Schematics Short Term Test Setup Photos Short Term Permanent* User’s Manual *Note: ______(Insert Explanation as Necessary)______ ______ FCC ID: XMR2021SC200LEM _____ has spent substantial effort in developing this product and it is one of the first of its kind in industry. Having the subject information easily available to "competition" would negate the advantage they have achieved by developing this product. Not protecting the details of the design will result in financial hardship. Permanent Confidentiality: The applicant requests the exhibits listed above as permanently confidential be permanently withheld from public review due to materials that contain trade secrets and proprietary information not customarily released to the public. Short-Term Confidentiality: The applicant requests the exhibits selected above as short term confidential be withheld from public view for a period of ______ days from the date of the Grant of Equipment Authorization and prior to marketing. This is to avoid premature release of sensitive information prior to marketing or release of the product to the public. Applicant is also aware that they are responsible to notify TCB in the event information regarding the product or the product is made available to the public. TCB will then release the documents listed above for public disclosure pursuant to FCC Public Notice DA 04-1705. NOTE for Industry Canada Applications: The applicant understands that until such time that IC distinguishes between Short Term and Permanent Confidentiality, either type of marked exhibit above will simply be marked Confidential when submitted to IC.

Quectel Wireless Solutions Company Limited Declaration of the Modular Approval A pplicant / Grantee Quectel Wireless Solutions Company Limited FCC ID: XMR2021SC200LEM Model: SC200L‐EM The single module transmitter has been evaluated then tested meeting the requirements under Part 15C Section 212 as below: Modular approval requirement EUT Condition Comply (a) The radio elements of the modular transmitter must have their own shielding. The physical crystal and tuning capacitors may be located external to the shielded radio elements. The radio elements of the modular transmitter have their own shielding. YES (b) 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. The modular has buffered data inputs, it is integrated in chip. Please see schematic.pdf YES (c)The modular transmitter must have its own power supply regulation. All power lines derived from the host device are regulated before energizing other circuits internal to SMART MODULE . Please see schematic.pdf YES (d) 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. Device uses a micro-strip trace on the host’s printed circuit board to an antenna connector on the host circuit board. YES (e)The modular transmitter must be tested in a stand-alone configuration, i.e., the module must not be inside another device during testing for compliance with part 15 requirements. 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 SMART MODULE was tested in a stand‐alone configuration via a PCMCIA extender. Please see spurious set‐up YES Quectel Wireless Solutions Company Limited 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 the 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 and commercially available (see Section 15.31(i)) must not be in side another device during testing. (f)The modular transmitter must be equipped with either a permanently affixed label or must be capable of electronically displaying its FCC identification number. The label position of SMART MODULE is clearly indicated. If the FCC ID of the module cannot be seen when it is installed, then the host label must include the text: Contains FCC ID: XMR2021SC200LEM. Please see the label.pdf YES (g) The modular transmitter must comply with any specific rules or operating requirements that ordinarily apply to a complete transmitter and the manufacturer must provide adequate instructions along with the module to explain any suchrequirements. A copy of these instructions must be included in the application for equipmentauthorizationrequirements,whicharebas edon theintendeduse/configurations. SMART MODULE is compliant with all applicable FCC rules. Detail instructions are given in the User Manual. YES (h)The modular transmitter must comply with any applicable RF exposure requirements in its final configuration. SMART MODULE is approved to comply with the applicable RF exposure requirement, please see the MPE evaluation with 20cm as the distance restriction.
