      Reference Document(s): See Normative References


Test Procedure for Fundamental Emission Output Power Measurement
In the case of average power measurements an average power sensor was utilized.

For peak power measurements the spectrum analyzer built-in power function was used to integrate peak power over the 20 dB
bandwidth.

Testing was performed under ambient conditions at nominal voltage only. Where the device operated with multiple antenna ports i.e.
MIMO device, each port was measured, summed (Σ) and reported.

Test configuration and setup used for the measurement was per the Conducted Test Set-up specified in this document.
Supporting Information
Calculated Power = A + G + Y+ 10 log (1/x) dBm

A = Total Power [10*Log10 (10a/10 + 10b/10 + 10c/10 + 10d/10)]
G = Antenna Gain
Y = Beamforming Gain
x = Duty Cycle (average power measurements only)

Limits for Fundamental Emission Output Power
(b) The maximum peak conducted output power of the intentional radiator shall not exceed the following for non-frequency hopping
systems:

      (3) For systems using digital modulation in the 902-928 MHz and 2400-2483.5 MHz bands: 1 Watt. As an alternative to a peak
      power measurement, compliance with the one Watt limit can be based on a measurement of the maximum conducted output
      power. Maximum Conducted Output Power is defined as the total transmit power delivered to all antennas and antenna
      elements averaged across all symbols in the signaling alphabet when the transmitter is operating at its maximum power control
      level. Power must be summed across all antennas and antenna elements. The average must not include any time intervals
      during which the transmitter is off or is transmitting at a reduced power level. If multiple modes of operation are possible (e.g.,
      alternative modulation methods), the maximum conducted output power is the highest total transmit power occurring in any
      mode.

      (4) The conducted output power limit specified in paragraph (b) of this section is based on the use of antennas with directional
      gains that do not exceed 6 dBi. Except as shown in paragraph (c) of this section, if transmitting antennas of directional gain
      greater than 6 dBi are used, the conducted output power from the intentional radiator shall be reduced below the stated values
      in paragraphs (b)(3) of this section, as appropriate, by the amount in dB that the directional gain of the antenna exceeds 6 dBi.



(c) Operation with directional antenna gains greater than 6 dBi.
     (1) Fixed point-to-point operation:
           (i) Systems operating in the 2400-2483.5 MHz band that are used exclusively for fixed, point-to-point operations may
           employ transmitting antennas with directional gain greater than 6 dBi provided the maximum conducted output power of
           the intentional radiator is reduced by 1 dB for every 3 dB that the directional gain of the antenna exceeds 6 dBi.

        operations. The instruction manual furnished with the intentional radiator shall contain language in the installation
        instructions informing the operator and the installer of this responsibility.

  (2) In addition to the provisions in paragraphs (b)(3), (b)(4) and (c)(1)(i) of this section, transmitters operating in the 2400-2483.5
  MHz band that emit multiple directional beams, simultaneously or sequentially, for the purpose of directing signals to individual
  receivers or to groups of receivers provided the emissions comply with the following:

        (i) Different information must be transmitted to each receiver.

        (ii) If the transmitter employs an antenna system that emits multiple directional beams but does not do emit multiple
        directional beams simultaneously, the total output power conducted to the array or arrays that comprise the device, i.e.,
        the sum of the power supplied to all antennas, antenna elements, staves, etc. and summed across all carriers or frequency
        channels, shall not exceed the limit specified in paragraph (b)(1) or (b)(3) of this section, as applicable. However, the total
        conducted output power shall be reduced by 1 dB below the specified limits for each 3 dB that the directional gain of the
        antenna/antenna array exceeds 6 dBi. The directional antenna gain shall be computed as follows:

              (A) The directional gain shall be calculated as the sum of 10 log (number of array elements or staves) plus the
              directional gain of the element or stave having the highest gain.

              (B) A lower value for the directional gain than that calculated in paragraph (c)(2)(ii)(A) of this section will be accepted
              if sufficient evidence is presented, e.g., due to shading of the array or coherence loss in the beamforming.

        (iii) If a transmitter employs an antenna that operates simultaneously on multiple directional beams using the same or
        different frequency channels, the power supplied to each emission beam is subject to the power limit specified in
        paragraph (c)(2)(ii) of this section. If transmitted beams overlap, the power shall be reduced to ensure that their aggregate
        power does not exceed the limit specified in paragraph (c)(2)(ii) of this section. In addition, the aggregate power
        transmitted simultaneously on all beams shall not exceed the limit specified in paragraph (c)(2)(ii) of this section by more
        than 8 dB.

        (iv) Transmitters that emit a single directional beam shall operate under the provisions of paragraph (c)(1) of this section.

Test Procedure for Power Spectral Density
The transmitter output was connected to a spectrum analyzer and the measured made in a 3 kHz resolution bandwidth using the
analyzer auto-coupled sweep-time. A peak value was found over the full emission bandwidth and the spectrum downloaded for post
processing purposes.

Where the device operated with multiple antenna ports i.e. MIMO device, each port was measured separately. The Peak Power
Spectral Density is the highest level found across the emission bandwidth. With multiple antenna port measurements the numerical
analyzer data from each port is summed (å) and a link to this additional graphic is provided.

Testing was performed under ambient conditions at nominal voltage only.

Test configuration and setup used for the measurement was per the Conducted Test Set-up specified in this document.

Measure and sum the spectra across the outputs. With this technique, spectra are measured at each output of the device at the
required resolution bandwidth. The individual spectra are then summed mathematically in linear power units. Unlike in-band power
measurements, in which the sum involves a single measured value (output power) from each output, measurements for compliance
with PSD limits involve summing entire spectra across corresponding frequency bins on the various outputs. Consistency is
maintained for any device with multiple transmitter outputs to be certain the individual outputs are all aligned with the same span and
same number of points. In this instance, the linear power spectrum value within the first spectral bin of output 0 is summed with that in
the first spectral bin of output 1, and the first spectral bin of output 2, and so on up to the Nth output to obtain the true value for the
first frequency bin of the summed spectrum. The summed spectrum value for each frequency bin is computed in this fashion. These
summed spectral values were post processed and the resulting numerical and graphical data presented.

NOTE:
It may be observed that the spectrum in some antenna port plots break the limit line however this in itself does NOT constitute a
failure. In all cases a spectrum summation plot is provided in order to prove compliance. A failure occurs only after the summation
of all spectrum plots have been summed and are found to be greater than the limit line.

Supporting Information
Calculated Power = A + 10 log (1/x) dBm
A = Total Power Spectral Density [10 Log10 (10a/10 + 10b/10 + 10c/10 + 10d/10)]
x = Duty Cycle

Limits Power Spectral Density
For digitally modulated systems, the power spectral density conducted from the intentional radiator to the antenna shall not be greater
than +8 dBm in any 3 kHz band during any time interval of continuous transmission. This power spectral density shall be determined
in accordance with the provisions of paragraph (b) of this section. The same method of determining the conducted output power shall
be used to determine the power spectral density.

Test Procedure for Transmitter Conducted Spurious and Band-Edge Emissions Measurement
Transmitter Conducted Spurious and Band-Edge emissions were measured at a limit of 30 dBc (average detector) or 20 dBc (peak
detector) below the highest in-band spectral density measured with a spectrum analyzer connected to the antenna terminal.
Measurements were made while EUT was operating in transmit mode of operation at the appropriate centre frequency closest to the
band-edge. Emissions were maximized during the measurement and limits derived from the peak spectral power and drawn on each
plot.

Where the device operated with multiple antenna ports i.e. MIMO device, each port was measured separately. Testing was
performed under ambient conditions at nominal voltage only.

Test configuration and setup used for the measurement was per the Conducted Test Set-up specified in this document.

Limits Transmitter Conducted Spurious and Band-Edge Emissions
(d) In any 100 kHz bandwidth outside the frequency band in which the spread spectrum or digitally modulated intentional radiator is
operating, the radio frequency power that is produced by the intentional radiator shall be at least 20 dB below that in the 100 kHz
bandwidth within the band that contains the highest level of the desired power, based on either an RF conducted or a radiated
measurement, provided the transmitter demonstrates compliance with the peak conducted power limits. If the transmitter complies
with the conducted power limits based on the use of RMS averaging over a time interval, as permitted under paragraph (b)(3) of this
section, the attenuation required under this paragraph shall be 30 dB instead of 20 dB. Attenuation below the general limits specified
in §15.209(a) is not required. In addition, radiated emissions which fall in the restricted bands, as defined in §15.205(a), must also
comply with the radiated emission limits specified in §15.209(a) (see §15.205(c)).
