The applicant has been cautioned as to the following


15.21 - Information to User

The user’s manual or instruction manual for an intentional radiator shall caution the user that changes or modifications not
expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment.

15.27(a) - Special Accessories

Equipment marked to a consumer must be capable of complying with the necessary regulations in the configuration in
which the equipment is marketed. Where special accessories, such as shielded cables and/or special connectors are
required to enable an unintentional or intentional radiator to comply with the emission limits in this part, the equipment
must be marketed with, i.e. shipped and sold with, those special accessories. However, in lieu of shipping or packaging
the special accessories with the unintentional or intentional radiator, the responsible party may employ other methods of
ensuring that the special accessories are provided to the consumer without an additional charge.

Information detailing any alternative method used to supply the special accessories for a grant of equipment authorization
or retained in the verification records, as appropriate. The party responsible for the equipment, as detailed in § 2.909 of
this chapter, shall ensure that these special accessories are provided with the equipment. The instruction manual for such
devices shall include appropriate instructions on the first page of text concerned with the installation of the device that
these special accessories must be used with the device. It is the responsibility of the user to use the needed special
accessories supplied with the equipment.

Conducted Spurious Emissions
Engineer: Paul Hay
Test Date: 5/11/16

                                                   Test Requirements

                               Unwanted Emissions that fall Outside Restricted Bands

For transmitters operating in the 5.25-5.35 GHz band: All emissions outside of the 5.15-5.35 GHz band shall not exceed
an e.i.r.p. of −27 dBm/MHz.

For transmitters operating in the 5.47-5.725 GHz band: All emissions outside of the 5.47-5.725 GHz band shall not
exceed an e.i.r.p. of −27 dBm/MHz.

As specified in § 15.407(b), emissions above 1000 MHz that are outside of the restricted bands are subject to a maximum
emission limit of -27 dBm/MHz. However, an out-of-band emission that complies with both the peak and average limits of
§ 15.209 is not required to satisfy the -27 dBm/MHz maximum emission limit.

The emission measurements shall be performed using a minimum resolution bandwidth of 1 MHz. A lower resolution
bandwidth may be employed near the band edge, when necessary, provided the measured energy is integrated to show
the total power over 1 MHz

The provisions of §15.205 apply to intentional radiators operating under this section

Unwanted emissions below 1 GHz must comply with the general field strength limits set forth in §15.209.

                            For Conducted Unwanted Emissions in the Restricted Bands

For conducted measurements above 1000 MHz, EIRP was determined and then the field strength computed by the
following:
E[dBμV/m] = EIRP[dBm] - 20 log(d[meters]) + 104.77, where E = field strength and d = 3m
E[dBμV/m] = EIRP[dBm] + 95.2, for d = 3 meters.

                                                     Test Procedure

Per KDB 789033 D02 General U-NII Test Procedures New Rules v01 conducted RF port measurements were made in
lieu of radiated. In addition, Cabinet Emissions measurements were performed in a semi-anechoic chamber with the
antenna port terminated by a matching load. See additional section for Radiated Emissions.

The following criteria were addressed:

The Spectrum Analyzer was set to the following for emissions > 1000MHz:
   a. RBW = 1 MHz
   b. VBW ≥ 3 MHz
   c. Detector = Peak.
   d. Sweep time = auto
   e. Trace mode = max hold
      1. Note: For emissions where the peak exceeded that of the average 15.209 emission limit the following was
          performed.
   f. VBW ≤ RBW/100 (i.e., 10 kHz) but not less than 10 Hz

For emissions below 1000MHz the Spectrum Analyzer settings were as follows:
    a. RBW = 100 kHz
    b. VBW ≥ 300 kHz
    c. Detector = Peak
    d. Sweep time = auto
    e. Trace mode = max hold

                                                    Test Procedure

The EUT was setup in accordance with ANSI C63.10. 2009 and tested per KDB 789033. The antenna was replaced with
non-radiating matched load. The EUT is placed on non-conductive platform at a height of 0.8 meters above the ground
plane of the semi-anechoic chambers. The EUT was rotated 360 degrees and the receive antenna raised and lowered to
find the maximum emissions from 30MHz to the 10th harmonic of the fundamental. The EUT was set to the maximum
power level allowed and the low, mid, and high channels were investigated for emissions.

The Spectrum Analyzer was set to the following for emissions > 1000MHz:

    a. (RBW = 1 MHz
    b. VBW ≥ 3 MHz
    c. Detector = Peak
    d. Sweep time = auto
    e. Trace mode = max hold
       1. Note: For emissions where the peak exceeded that of the average 15.209 emission limit the following was
           performed.
    f. RBW = 1 MHz
    g. VBW ≤ RBW/100 (i.e., 10 kHz) but not less than 10Hz

For emissions below 1000MHz the Spectrum Analyzer settings were as follows:

    a.   RBW = 100 kHz
    b.   VBW ≥ 300 kHz
    c.   Detector = Peak
    d.   Sweep time = auto
    e.   Trace mode = max hold
         1. Note: A quasi peak detector was used for emissions where the peak exceeded that of the average 15.209
             emission limits

                                                   Test Requirement

The emission bandwidth shall be determined by measuring the width of the signal between two points, one below the
carrier center frequency and one above the carrier center frequency, that are 26 dB down relative to the maximum level of
the modulated carrier. Determination of the emissions bandwidth is based on the use of measurement instrumentation
employing a peak detector function with an instrument resolution bandwidth approximately equal to 1.0 percent of the
emission bandwidth of the device under measurement


                                                    Test Procedure

The Spectrum Analyzer was set to the following parameters:

    a.   RBW = approximately 1 to 5% of the emission bandwidth.
    b.   VBW > RBW.
    c.   Detector = Peak.
    d.   Trace mode = max hold.

emissions. In addition, systems operating under the provisions of this section shall be operated in a manner that insures
that the public is not exposed to radio frequency energy levels in excess of the Commission’s guidelines.

                                                    Exposure Limits

At operating frequencies less than or equal to 6 GHz, the limits for maximum permissible exposure (MPE) shall be used to
evaluate the environmental impact of human exposure to radiofrequency (RF) radiation as specified in Section 1.1307(b),
except for portable devices as defined in §2.1093 as these evaluations shall be performed according to the SAR
provisions in §2.1093 of this chapter.

A/C Powerline Conducted Emission
Engineer: Paul Hay
Test Date: 5/12/16

                                                    Test Procedure

The EUT power cable was connected to a LISN and the monitored output of the LISN was connected to a transient limiter,
which then connected directly to a spectrum analyzer. The conducted emissions from 150 kHz to 30 MHz were measured
and compared to the specification limits.

Emissions at Band Edges
Engineer: Poona Saber
Test Date: 5/19/16

                                                     Test Procedure

The EUT was tested in a semi-anechoic chamber set 3m from the receiving antenna. A spectrum analyzer was used to
verify that the EUT met the requirements for band edge and restricted band for both peak and average measurements.
The cable and antenna correction factors were input into the analyzer as a reference level offset to ensure accurate
readings. For the restricted band the amplifier and band reject filter correction factors were also input to the spectrum
analyzer.

    (i)     For an outdoor access point operating in the band 5.25-5.35 GHz, the maximum power spectral density shall
            not exceed -13 dBW in any 1 megahertz band for 0°≤ θ< 8°, -13 − 0.716 (θ-8) dBW/MHz for 8° ≤ θ< 40°, -35.9
            − 1.22 (θ-40) dBW/MHz for 40° ≤ θ ≤ 45° and -42 dBW/MHz for θ > 45°. θ is the angle above the local
            horizontal plane (of the Earth). For ease of testing the following conversion was used.

1dbW=31dBm
