Modular Approval Request FCC (KDB 996369 D01 & Part 15.212)
FCC ID: NKR-P11

Items to be covered by Single modular transmitters.                                        Answer from applicant
1. The modular transmitter must have its own RF shielding.                                 The modular has a shielding
                                                                                           Case. Please refer to EUT
                                                                                           Photo.
2.    The modular transmitter must have buffered modulation/data inputs (if such inputs    The component number is
      are provided) to ensure that the module will comply with Part 15 requirements        RTL8711AM
      under conditions of excessive data rates or over-modulation.
3.    The modular transmitter must have its own power supply regulation.                   The component number is
                                                                                            AP3428DNTR-G1
4.    The modular transmitter must comply with the antenna requirements of Section         No antenna connector is used.
      15.203 and 15.204(b)(c). The antenna must either be permanently attached or          And no external amplifier will
      employ a “unique” antenna coupler (at all connections between the module and the     be used with this modular.
      antenna, including the cable).

 5.   The modular transmitter must be tested in a stand-alone configuration, i.e., the     This modular is tested under
      module must not be inside another device during testing. This is intended to         stand-alone configuration.
      demonstrate that the module is capable of complying with Part 15 emission limits     Please refer to Test setup
      regardless of the device into which it is eventually installed.                      photo.

 6. The modular transmitter must be equipped with either a permanently affixed label       The modular transmitter is
    or must be capable of electronically displaying its FCC identification number in       labeled with its own FCC ID
    accordance with 15.212 (a)(1)(vi)(A) / (B).                                            number. Please refer to label
                                                                                           sample and label location.
7. The modular transmitter must comply with any specific rule or operating                 The modular complies with
   requirements applicable to the transmitter and the manufacturer must provide             this requirement. Please refer
   adequate instructions along with the module to explain any such requirements. A          to user manual.
   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                  The device complies with this
      requirements. For example, FCC Rules in Sections 1.1310, 2.1091, 2.1093, and         requirement. Please refer to
      specific Sections of Part 15, including 15.319(i), 15.407(f), 15.253(f) and          RF exposure report.
      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.


                                                                                                               RF_734_02
                                                                                                              04 April 16



 Items to be covered by Split modular transmitters.                                            Answer from applicant
 1. The modular transmitter must comply with all requirements of a single modular
     transmitter except for items (1) & (5) of the above single modular approval
     requirements.

 2.   Only the radio front end must be shielded. The physical crystal and tuning
      capacitors may be located external to the shielded radio elements. The interface
      between the split sections of the modular system must be digital with a minimum
      signalling amplitude of 150 mV peak-to-peak.

 3.   Control information and other data may be exchanged between the transmitter
      control elements and radio front end.

 4.   The sections of a split modular transmitter must be tested installed in a host
      device(s) similar to that which is representative of the platform(s) intended for use.

 5.   Manufacturers must ensure that only transmitter control elements and radio front
      end components that have been approved together are capable of operating together.
      The transmitter module must not operate unless it has verified that the installed
      transmitter control elements and radio front end have been authorized together.
      Manufacturers may use means including, but not limited to, coding in hardware and
      electronic signatures in software to meet these requirements, and must describe the
      methods in their application for equipment authorization.




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