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.

Average Output Power
 Engineer: Poona Saber
 Test Date: 1/2/2018
                                                     Test Requirements

 (i) For an outdoor access point operating in the band 5.15-5.25 GHz, the maximum conducted output power over the
frequency band of operation shall not exceed 1 W provided the maximum antenna gain does not exceed 6 dBi. 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. The maximum e.i.r.p. at any elevation
angle above 30 degrees as measured from the horizon must not exceed 125 mW (21 dBm).

(iii) For fixed point-to-point access points operating in the band 5.15-5.25 GHz, the maximum conducted output power
over the frequency band of operation shall not exceed 1 W. Fixed point-to-point U-NII devices may employ antennas with
directional gain up to 23 dBi without any corresponding reduction in the maximum conducted output power. For fixed
point-to-point transmitters that employ a directional antenna gain greater than 23 dBi, a 1 dB reduction in maximum
conducted output power is required for each 1 dB of antenna gain in excess of 23 dBi. Fixed, point-to-point operations
exclude the use of point-to-multipoint systems, omnidirectional applications, and multiple collocated transmitters
transmitting the same information. The operator of the U-NII device, or if the equipment is professionally installed, the
installer, is responsible for ensuring that systems employing high gain directional antennas are used exclusively for fixed,
point-to-point operations.

In addition to the emission limits specified in § 15.407(a)(1)(i), if the access point is an outdoor Point-to-Multipoint device
operating in the band 5.15-5.25 GHz, the rules require that the maximum EIRP at any elevation angle above 30° not
exceed 125 mW (21 dBm) as measured from the horizon. This restriction leads to a general requirement for the antenna
pattern: if the EIRP within 3-dB elevation beam width of any radiation lobe is higher than 125 mW, this lobe must be
controlled, either mechanically or electrically, so that the 3-dB elevation beam width of this lobe is below 30° elevation
angle relative to horizon.
For the purposes of compliance, information for all the antenna types must be included in the filing. In order for antennas
to be considered of similar type, the antenna patterns must also be similar as well as other characteristics of the antenna.

Based on KDB 662911 D02 for Cross polarized antenna power was first measured radiated and the total emission was
derived from below steps
(1) Measured radiated emissions with vertical and horizontal polarizations of the measurement antenna
(2) Converted each radiated measurement to transmit power or PSD based on the antenna gain
(3) Summed the powers or PSDs across the two polarizations
                                                    Test Procedure

Testing was done Radiated at 1 meters distance from EUT in anechoic chamber and the position of the EUT and antenna
was maximized to get the highest power reading out of the unit. 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

(i) For an outdoor access point operating in the band 5.15-5.25 GHz, the maximum power spectral density shall not
exceed 17 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. The maximum e.i.r.p. at any elevation angle above 30 degrees as measured from the horizon must not exceed 125
mW (21 dBm).


(iii) For fixed point-to-point access points operating in the band 5.15-5.25 GHz fixed point-to-point U-NII devices may
employ antennas with directional gain up to 23 dBi without any corresponding reduction in the maximum power spectral
density. For fixed point-to-point transmitters that employ a directional antenna gain greater than 23 dBi, a 1 dB reduction

All emissions outside of the 5.15-5.35 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.


In addition to above the provision of §15.209 were applied to meet the requirements of §15.205.

                                                  Test Procedure

The EUT was setup in accordance with ANSI C63.10. 2013 and tested per KDB 789033. The EUT is placed on non-
conductive platform at a height of 0.8 and 1.5 meters above the ground plane of the semi-anechoic chambers and 3
meters away from receiving antenna for below and above 1 GHz. The EUT was rotated 360 degrees and the receive
antenna raised and lowered to find the maximum emissions from 30MHz to the 10 th 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 Date: 1/2/18

                                                   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

For industry Canada the Occupied bandwidth will be the 99% emission bandwidth in megahertz.


                                                    Test Procedure

The Spectrum Analyzer was set to the following parameters:

    a.   RBW = approximately 1% 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.
