Modular Approval Request FCC (KDB 996369 D01 & Part 15.212)
FCC ID: RRK-WMCAC15

 Items to be covered by Single modular transmitters.                                       Answer from applicant
 1. The modular transmitter must have its own RF shielding.                                YES, Please refer to External
                                                                                            Photos.
 2.   The modular transmitter must have buffered modulation/data inputs (if such inputs    YES, U1 RTL8211F is used for
      are provided) to ensure that the module will comply with Part 15 requirements         the function.
      under conditions of excessive data rates or over-modulation.
 3.   The modular transmitter must have its own power supply regulation.                   YES, the modular has its own
                                                                                            power supply regulation.
 4.   The modular transmitter must comply with the antenna requirements of Section         YES, it is PCB antenna.
      15.203 and 15.204(b)(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).

 5.   The modular transmitter must be tested in a stand-alone configuration, i.e., the      No, U-NII modular devices with
      module must not be inside another device during testing. This is intended to          radar detection are typically filed
      demonstrate that the module is capable of complying with Part 15 emission limits     .as limited modules for the
                                                                                            specific receive antennas.
      regardless of the device into which it is eventually installed.

 6. The modular transmitter must be equipped with either a permanently affixed label       YES, please refer to the
    or must be capable of electronically displaying its FCC identification number in        exhibition label sample for this
    accordance with 15.212 (a)(1)(vi)(A) / (B).                                             module.

 7. The modular transmitter must comply with any specific rule or operating                YES, please refer to the user
    requirements applicable to the transmitter and the manufacturer must provide            manual.
    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. For example, there are very strict operational and timing
    requirements that must be met before a transmitter is authorized for operation under
    Section 15.231. For instance, data transmission is prohibited, except for operation
    under Section 15.231(e), in which case there are separate field strength level and
    timing requirements. Compliance with these requirements must be assured.

 8.   The modular transmitter must comply with any applicable RF exposure                  YES, RF exposure statement is
      requirements. For example, FCC Rules in Sections 1.1310, 2.1091, 2.1093, and          attached in the user manual.
      specific Sections of Part 15, including 15.319(i), 15.407(f), 15.253(f) and
      15.255(g), require that Unlicensed PCS, UNII and millimeter wave devices
      perform routine environmental evaluation for RF Exposure to demonstrate
      compliance. In addition, spread spectrum transmitters operating under Section
      15.247 are required to address RF Exposure compliance. Modular transmitters
      approved under other Sections of Part 15, when necessary, may also need to
      address certain RF Exposure concerns, typically by providing specific
      installation and operating instructions for users, installers and other interested
      parties to ensure compliance.




Note: A limited modular approval (LMA) may be granted for single or split modular transmitters
that comply partially with the requirements above.
