Applicant Suzhou Pairlink Network Technology Ltd. FCC ID: 2AQV6MOUSELET-B Section 15.212 Modular Transmitters Request for Modular Approval Request for Limited Modular Approval  RequirementsEUT ConditionsComply(Y/N) Single Modular Approval Requirements 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. Refer to external photos. This module have shield cover. Y 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. All inputs to the modules are buffered through logic or microprocessor inputs. Refer to Schematics. Y 3 The modular transmitter must have its own power supply regulation. The Module uses the chip CYW20736 with built-in power management components, the module rated power is DC1.65-3.6V, Refer to schematics. Y 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 modular transmitter has a Patch antenna arrangement for BLE, Refer to EUT photo. Y Company: Suzhou Pairlink Network Technology Ltd. Add: Room 117, No.55, Su hong xi Road, Suzhou Industrial Park, Suzhou City, Jiangsu Province, China Tel: 0512-85889528 Fax: 0512-85889528 E-mail: [email protected] 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 market ed 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 test ing shall be unmodified and commercially available (see §15.31(i)). The modular transmitter is connected to the controlled board when testing. Please refer to setup photo. Y 6 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:“ContainsTransmitter Module FCC ID: 2AQV6MOUSELET-B”Any similarwording that e xpresses the same meaning may be used. The Grantee may either provide such a label, an example of which must be included Refer to the label. Y 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. 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. Refer to manual Y 8 The modular transmitter must comply with any applicable RF exposure requirements in its final configuration. The EUT comply with any applicable RF exposure requirements in its final configuration. Y Sincerely, Signature: Typed or Printed Name: Yi Cai Title: CEO

Bay Area Compliance Laboratories Corp. (Kunshan) Report No.: RSHD200106004-00A FCC Part 15.247 Page 12 of 39 FCC §1.1310& §2.1091 - MAXIMUM PERMISSIBLE EXPOSURE (MPE) Applicable Standard According to subpart 15.247(i) and subpart §1.1310, systems operating under the provisions of this section shall be operated in a manner that ensures that the public is not exposed to radio frequency energy level in excess of the Commission’s guidelines. Limits for Maximum Permissible Exposure (MPE) (§1.1310, §2.1091) (B) Limits for General Population/Uncontrolled Exposure Frequency Range (MHz) Electric Field Strength (V/m) Magnetic Field Strength (A/m) Power Density (mW/cm 2 ) Averaging Time (minutes) 0.3-1.34 614 1.63 *(100) 30 1.34-30 824/f 2.19/f *(180/f²) 30 30-300 27.5 0.073 0.2 30 300-1500 / f/1500 30 1500-100,000 / 1.0 30 f = frequency in MHz; * = Plane-wave equivalent power density; According to §1.1310 and §2.1091 RF exposure is calculated. Calculated Formulary: Predication of MPE limit at a given distance S = PG/4πR² = power density (in appropriate units, e.g. mW/cm 2 ); P = power input to the antenna (in appropriate units, e.g., mW); G = power gain of the antenna in the direction of interest relative to an isotropic radiator, the power gain factor, is normally numeric gain; R = distance to the center of radiation of the antenna (appropriate units, e.g., cm); Calculated Data: Mode Frequency Range (MHz) Antenna Gain Tune-up Conducted Power Evaluation Distance (cm) Power Density (mW/cm 2 ) MPE Limit (mW/cm 2 ) (dBi) (numeric) (dBm)(mW) BLE 2402~2480 2.00 1.58 2.5 1.78 20 0.0006 1.0 Note: For the above Tune-up Conducted power were declared by the manufacturer. Conclusion: The EUT meets exemption requirement - RF exposure evaluation greater than 20cm distance specified in § 2.1091. If the device built into a host as a portable usage, the additional RF exposure evaluation may be required as specified by§ 2.1093.
