October 20, 2023 Attestation Letter for Low Power Indoor Client Module Approval FCC ID: A3LWCD940M We, Samsung Electronics Co Ltd attest that this device under FCC ID: A3LWCD940M complies with device protocol requirements and operational restrictions: for indoor client 6XD. a. Contention-based protocol, as demonstrated in the test report, is permanently embedded in the module and is not host-dependent. The device will only associate and connect with a low-power indoor access b. point or subordinate device and never directly connect to other client devices. This device will always initiate transmission under the control of a low-power c. indoor AP or subordinate except for brief transmissions before joining a network. These short messages will only occur if the client has detected an indoor AP or subordinate operating on a channel. These brief messages will have a time-out mechanism such that if it does not receive a response from an AP it will not continually repeat the request. Transmissions will be lower or equal to the power advertised by the indoor d. low-power access point or subordinate and never above the maximum output power allowed by the FCC grant for equipment class 6XD. e. This device does not have its own direct internet connection. Furthermore, we fully understand this device is prohibited for control of or communications with unmanned aircraft systems, including drones. For any questions, please contact me at your convenience.

Modular Approval Request FCC (Per 15.212) FCC ID: A3LWCD940M Answer From Applican t Yes Yes Yes Yes Yes Items to be covered 1. 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. 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. 3. The modular transmitter must have its own power supply regulation. 4. The modular transmitter must comply with the antenna and transmission system requirements of 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 15.203 is not applicable to modules but can apply to limited modular approvals under paragraph (b) of this section. 5. 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 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 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 15.31(i)). 6. The modular transmitter must be equipped with either a permanently affixed label or must be capable of electronically displaying its FCC identification number. Yes

(A) If using a permanently affixed label, the modular transmitter must be labeled with its own FCC identification number, and, if the FCC identification number 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: XYZMODEL1 or Contains FCC ID: XYZMODEL1. 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.

(B) 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. 7. 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 such requirements. A copy of these instructions must be included in the application for equipment authorization. 8. Radio frequency devices operating under the provisions of this part are subject to the radio frequency radiation exposure requirements specified in 1.1307(b), 1.1310, 2.1091, and 2.1093 of this chapter, as appropriate. Applications for equipment authorization of modular transmitters under this section must contain a statement confirming compliance with these requirements. The modular transmitter must comply with any applicable RF exposure requirements in its final configuration. Technical information showing the basis for this statement must be submitted to the Commission upon request. Yes Yes Note: If compliance with one or more of the numbered requirements, listed above, cannot be demonstrated, it may be possible to obtain a Limited Modular Approval (LMA).
