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.

Standard Test Conditions Engineering Practices

Except as noted herein, the following conditions and procedures were observed during the testing:

In accordance with ANSI C63.10-2013 and unless otherwise indicated in the specific measurement results, the ambient
temperature of the actual EUT was maintained within the range of 10° to 40°C (50° to 104°F) unless the particular
equipment requirements specified testing over a different temperature range. Also, unless otherwise indicated, the
humidity levels were in the range of 10% to 90% relative humidity.

Measurement results, unless otherwise noted, are worst-case measurements.

EUT Operation during Tests
EUT is powered by POE (Power over Ethernet) Ethernet cable.


EUT Description
Model: B-DB-AC, Bullet & Bullet AC-IP67
Description: Dual Band Networking Device
Firmware: V8.6
Software: ART
Serial Number: N/A
Additional Information: The Bullet AC (Model: B-DB-AC) is a dual band networking device that is powered over ethernet
(passive POE, 24V) and provides an N-type antenna connection. It features dual-band AC mode operation in 5GHz and
2.4GHz bands, and a dedicated 2.4 GHz WiFi management radio for convenient device setup.

For 5 GHz band the radio covers 802.11 a/n/ ac modes with 10,20,30,40,50,60 and 80 MHz bandwidth. It is evaluated that
unit would represent worst case operation and highest power number with ac mode and only result of testing is
represented for this mode.

Bullet AC-IP67 is electrically identical to B-DB-AC device and it incorporates an outdoor housing which is made of metal
instead of plastic


EUT Operation during Tests
Radio testing has been done conducted and radiated with controlling the device for continuous modulation transmission
on low, middle and high channels with client’s provided commands through telnet.

Peak Output Power

Test Date: 10/30/17-11/7/17

                                                    Test Requirements
For the 5.25-5.35 GHz and 5.47-5.725 GHz bands, the maximum conducted output power over the frequency bands of
operation shall not exceed the lesser of 250 mW or 11 dBm + 10 log B, where B is the 26 dB emission bandwidth in
megahertz. If transmitting antennas of directional gain greater than 6 dBi are used, the maximum conducted output power
shall be reduced by the amount in dB that the directional gain of the antenna exceeds 6 dBi.

In addition to the above requirements, Per industry Canada RSS 247 devices shall comply with the following, where
applicable:

Outdoor fixed devices with a maximum e.i.r.p. greater than 200 mW shall comply with the following e.i.r.p. at different
elevations, where θ is the angle above the local horizontal plane (of the Earth) as shown below:

            i.   -13 dBW/MHz for 0°≤ θ< 8°
           ii.   -13 −0.716 (θ-8) dBW/MHz        for 8° ≤ θ< 40°
          iii.   -35.9 −1.22 (θ-40) dBW/MHz      for 40° ≤ θ ≤45°
          iv.    -42 dBW/MHz for θ > 45°

Note: Antenna pattern measurements have been done on all 4 antennas for both azimuth and elevation and the highest
measured gain for all 4 different type antennas is 0 dBi. Hence the highest EIRP per power results in the Annex A below
would be 22 dBm which is less than 200 mW hence, testing for different elevation is not required.


                                                 Test Procedure
The RF power was calculated using the spectrum analyzers’ band power function per Method SA-1 from KDB 789033
D02 General U-NII Test Procedures New Rules v01. Measurements were made at the low, mid, and high channels of the
band.

The Spectrum Analyzer was set to the following:
   a. RBW = 1 MHz
   b. VBW ≥ 3 MHz
   c. Sweep time = auto
   d. Detector = RMS
   e. 100 traces in power averaging mode

The Conducted power limit for each of the antennas used with the device are as following:

4 dBi Antenna allows 24 dBm power
13 dBi Antenna allows 17dBm power: 13dBi - 6dB= 7dB => 24dBm - 7dB=17dBm
22 dBi Antenna allows 8 dBm power: 22dBi - 6dB= 16dB => 24dBm - 16dB= 8dBm
34 dBi Antenna allow -6 dBm power: 34dBi - 6dB= 28dB => 24dBm - 28dB= -4dBm

                                                 Test Requirements

For the 5.25-5.35 GHz and 5.47-5.725 GHz bands, the maximum power spectral density shall not exceed 11 dBm in any
1 megahertz band. If transmitting antennas of directional gain greater than 6 dBi are used, the maximum power spectral
density shall be reduced by the amount in dB that the directional gain of the antenna exceeds 6 dBi.



                                                   Test Procedure

The Power Spectral Density was measured using the method per SA-1 from KDB 789033 D02 General U-NII Test
Procedures New Rules v01. Measurements were made at the low, mid, and high channels of the band. The maximum
PSD was determined by finding the peak value across the carrier bandwidth.

The Spectrum Analyzer was set to the following:
   a. RBW = 1 MHz
   b. VBW ≥ 3 MHz

Undesirable Emissions Conducted
Engineer: Poona Saber
Test Date: 10/30/17-11/7/17

                                                   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

                                                                            p1790008_FCC_Part 15.407_UNII-2_Rev 10.0
                                                                                                       Page 12 of 21


Note: per KDB 789033 and ANSI C63.10 for conducted measurement in lieu of radiated following values have been
added as an offset in the measurement plots :

   1) For conducted measurements in restricted band the filed strength shall be computed and an additional 4.7 dB
      shall be added as an upper bound on the field strength that would be observed on a test site with a ground plane
      for frequencies between 30 MHz and 1000 MHz.

   2)    A value representative of an upper bound on out-of-band antenna gain (in dBi) shall be added to the measured
        antenna-port conducted emission power to compute EIRP within the specified measurement bandwidth. (For
        emissions in the restricted bands, additional calculations are required to convert EIRP to field strength at the
        specified distance.) The upper bound on antenna gain for a device with a single RF output shall be selected as
        the maximum in-band gain of the antenna across all operating bands or 2 dBi, whichever is greater.


   3) Since the maximum measured antenna gain in all bands is 0 dBi a value of maximum 2 dBi has been added to
      compare the conducted power measurements to an EIRP limit.

        EIRP= Power (conducted) + Gain


   4) When a conducted power measurement is used to compare with Electric field (dBuV/m) limit an offset of –11.8 is
      added to measurement to compare conducted power (dBm) to electric field limit (dBuV/m) at 3 meters.

The EUT was setup in accordance with ANSI C63.10. 2013 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.

                                                     Requirements

U-NII devices are subject to the radio frequency radiation exposure requirements specified in §1.1307(b), §2.1091 and
§2.1093 of this chapter, as appropriate. All equipment shall be considered to operate in a “general
population/uncontrolled” environment. Applications for equipment authorization of devices operating under this section
must contain a statement confirming compliance with these requirements for both fundamental emissions and unwanted
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.
