C5266091_X9_Ed.2 1/1 WIRELESS-TAG TECHNOLOGY CO., LIMITED Modular Transmitter Approval Request Federal Communications Commission Equipment Authorization Branch 7435 Oakland Mills Road Columbia, MD 21046 Company name: WIRELESS-TAG TECHNOLOGY CO., LIMITED FCC ID: 2AFOS-WTLRC262-SG3 Gentlemen, In accordance with 47CFR 15.212 Modular Transmitters and KDB 996369 D01 ‘Module Certification Guide v04 ’. FCC ID: 2AFOS-WTLRC262-SG3 has been examined against the following requirements. Items to be covered by Single modular transmitters. Requirement per 15.212(a)(1) and KDB 996369 D01 ‘Modular Certification Guide v04 Explanation from Grantee (do not write yes/no, but explain why product complies/how it is achieved) 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. Yes, The module has its own RF shield 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. Yes, The module has data transmission function and supports BLE&2.4G WLAN function. 3. The modular transmitter must have its own power supply regulation. Module with power regulation and support for DC 3.3V input 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. The module meets the antenna requirements. 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)). The module has been tested in a standalone configuration, see report for details C5266091_X9_Ed.2 1/1 6. The modular transmitter must be equipped with either a permanently affixed label or must be capable of electronically displaying its FCC identification number. (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. The module has its own FCC ID number. See the label for details. 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. The module meets any specific rules or operational requirements applicable to the transmitter 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. Answer: The module complies with any applicable RF exposure requirements, as detailed in the instructions. A limited modular approval (LMA) may be granted for single transmitters that comply partially with requirements above. C5266091_X9_Ed.2 1/1 Name: Louie Wang Date: 2024-07-22 Title: …
