1 General Information

1.1    Purpose of this Report

      This report is prepared as a means of conveying test results and information
concerning the suitability of this exact product for public distribution according to the
FCC Rules and Regulations Part 15, Section 249.

1.2    Characterization of Test Sample

      The sample used for testing was received by US Tech on August 6, 2019 in
good operating condition.

1.3    Product Description

       The Equipment Under Test (EUT) is the Cort Business Services, model
TAPDN-PIR-0001. It is a passive infrared sensor that is used to detect motion within
a short range of the device. This motion detection is then sent via LoRaWAN to a
local gateway, which is then transmitted to the cloud. Multiple sensors are typically
used in an environment and the data is aggregated together in the cloud to provide
information via an application about how spaces are utilized within the environment.
The devices also advertise a BLE beacon, allowing for a proximity connection to
perform diagnostics and OTA updates.

1.4    Configuration of Tested System

       The Test Sample was tested per ANSI C63.4:2014 and ANSI C63.4:2013,
Methods of Measurement of Low-Voltage Electrical and Electronic Equipment in the
Range of 9 kHz to 40 GHz for FCC subpart A Digital equipment Verification
requirements and per ANSI C63.10-2013, American National Standard of
Procedures for Compliance Testing of Unlicensed Wireless Devices for FCC subpart
C Intentional Radiators.

       A list of EUT and Peripherals is found in Table 1. A block diagram of the
tested system is shown in Figure 1. Test configuration photographs are provided in
separate Appendices.

1.5     Test Facility

        Testing was performed at US Tech's measurement facility at 3505 Francis
Circle, Alpharetta, GA 30004. This site has been fully described and registered with
the FCC. Its designation number is US5301. Additionally this site has also been fully
described and submitted to Industry Canada (ISED), and has been approved under
file number 9900A-1.

1.6     Related Submittals

        The EUT is subject to the following FCC authorizations:

        a)      Certification under section 15.207 and 15.209 as a transmitter.
        b)      Verification under 15.101 as a digital device.

        The Verification requirement shares many common report elements with the
Certification report. Therefore, though this report is mostly intended to provide data
for the Certification process, the Verification authorization report (Parts 15.107 and
15.109) for the EUT is included herein.

2.2    Modifications to EUT Hardware

       No physical modifications were made by US Tech in order to bring the EUT
into compliance with FCC Part 15, Subpart C Intentional Radiator Limits for the
transmitter portion of the EUT or the Subpart B Unintentional Radiator Limits
(Receiver and Digital Device) Requirements.

2.3    Number of Measurements for Intentional Radiators (15.31(m))

       Measurements of intentional radiators or receivers shall be performed and
reported for each band in which the device can be operated with the device
operating at the number of frequencies in each band specified in Table 3 below.

      Because the EUT operates at 2402 MHz to 2480 MHz, 3 test frequencies
were used.

2.4    Frequency Range of Radiated Measurements (Part 15.33)

2.4.1 Intentional Radiator

       The spectrum shall be investigated for the intentional radiator from the lowest
RF signal generated in the EUT, without going below 9 kHz to the 10 th harmonic of
the highest fundamental frequency generated or 40 GHz, whichever is the lowest.

2.4.2 Unintentional Radiator

      For the digital device, an unintentional radiator, the frequency range shall be
30 MHz to 1000 MHz, or to 5 times the highest internal clock frequency.

2.5    Measurement Detector Function and Bandwidth (CFR 15.35)

     The radiated and conducted emissions limits shown herein are based on the
parameters outlined following.

2.5.1 Detector Function and Associated Bandwidth

       On frequencies below 1000 MHz, the limits herein are based upon
measurement equipment employing a CISPR Quasi-peak detector function and
related measurement bandwidths (i.e. 9 kHz from 150 kHz to 30 MHz and 120 kHz
from 30 MHz to 1000 MHz). Alternatively, measurements may be made with
equipment employing a peak detector function as long as the same bandwidths
specified for the quasi-peak device are used.

2.5.2 Corresponding Peak and Average Requirements

       Above 1000 MHz, radiated limits are based on measuring instrumentation
employing an average detector function. When average radiated emissions are
specified there is also a corresponding Peak requirement, as measured using a
peak detector, of 20 dB greater than the average limit. For all measurements above
1000 MHz the Resolution Bandwidth shall be at least 1 MHz.

2.5.3 Pulsed Transmitter Averaging

      When the radiated emissions limit is expressed as an average value, and the
transmitter is pulsed, the measured field strength shall be determined by applying a
Duty Cycle Correction Factor based upon dividing the total ON time during the first
100 ms period by 100 ms (or by the period if less than 100 ms). The duty cycle may
be expressed logarithmically in dB.

       NOTE: If the transmitter was programmed to transmit at >98% duty cycle,
then, wherever applicable (where the detection mode was AVG), the duty cycle
factor calculated will be applied.

2.6    Transmitter Duty Cycle (CFR 15.35 (c))

       The operating duty cycle of the transmitter under normal operation was
calculated at 50 percent.

     Pulse transmitter averaging as detailed in clause 2.5.3 above is considered
whenever the EUT operation involves pulse transmission signals.




TXfull period= 2.11 mS, TXon = 1.07 mS
Duty Cycle = 20 Log (TX on/(Tx on+TX off)) = 20 Log (1.07/2.11) = -5.89

In this case a duty cycle correction factor of -5.89 dB was used to correct Peak
values to AVG values.


2.7    EUT Antenna Requirements (CFR 15.203)

        An intentional radiator shall be designed to ensure that no antenna other than
that furnished by the responsible party shall be used with the device. The use of a
permanently attached antenna or of an antenna that uses a unique coupling to the
intentional radiator shall be considered sufficient to comply with the provisions of this
section. Only the antenna(s) listed in Table 4 will be used with this module.

2.8    Restricted Bands of Operation (CFR 15.205)

       Only spurious emissions can fall in the frequency bands of CFR 15.205. The
field strength of these spurious emissions cannot exceed the limits of 15.209.
Radiated Harmonics and other Spurious Emissions are examined for this
requirement; see paragraph 2.1.

2.9    Intentional Radiator, Power Line Conducted Emissions (CFR 15.207)

       The EUT is powered by two AA Lithium batteries; therefore, this test is not
applicable.

2.10 Intentional Radiator, Radiated Emissions (CFR 15.209, 15.249(a)(c)) (IC
RSS 210, A2.9 (a))

       Radiated Radio measurements: the EUT was placed into a continuous
transmit mode of operation and a preliminary scan was performed on the EUT to find
signal frequencies that were caused by the transmitter part of the product. To obtain
the worst case results, the EUT was placed on a table top of a non-conductive table,
80 cm above the ground floor. The EUT was positioned 3 meters away from the
receiving antenna during testing (1 meter at frequencies above 6 GHz and if the
emissions were less than 6 dB from the noise floor). The EUT was tested in X, Y
and Z axes or the position of normal operation to determine the worst case
orientation. Radiated measurements below 30 MHz were tested with a RBW = 9
kHz; emissions below 1 GHz were tested with a RBW = 120 kHz and radiated
measurements above 1 GHz were measured using a RBW =1 MHz. VBW was set
to three times the RBW value.

2.11 Band Edge Measurements – (CFR 15.249 (d))

             Band Edge measurements are made following the guidelines in FCC
KDB Publication No. 558074 with the EUT initially operating on the Lowest Channel
and then operating on the Highest Channel within its band of operation. Radiated
measurements are performed to demonstrate compliance with the requirement of
15.249(d) that all emissions outside of the band edges be attenuated by at least 50
dB or 15.209 limits, when compared to its highest in-band value (contained in a 100
kHz band).

      To capture the band edge, set the Spectrum Analyzer frequency span set to 2
MHz to capture the peak level of the emission operating on the channel closest to
the band edge as well as any modulation products falling outside of the authorized
band of operation. See figure and calculations below for more detail.

       The power line conducted voltage emission measurements have been carried
out in accordance with CFR 15.107, per ANSI C63.4:2014, Paragraph 7, with a
spectrum analyzer connected to a LISN and the EUT placed into a continuous mode
of transmission.

      Since the EUT is battery powered, this test was not applied. The                  EUT     is
powered by two AA Lithium batteries.

2.14 Unintentional Radiator, Radiated Emissions (CFR 15.109)

    Radiated emissions disturbance Measurements were performed with an
instrument having both peak and quasi-peak detectors over the frequency range of
30 MHz to 12.5 GHz. Measurements of the radiated emissions were made with the
receiver antenna at a distance of 3 m from the boundary of the test unit.

        The test antenna was varied from 1 m to 4 m in height while watching the
analyzers’ display for the maximum magnitude of the signal at the test frequency.
The antenna polarization (horizontal or vertical) and test sample azimuth were varied
during the measurements to find the maximum field strength readings to record.

       The worst-case radiated emissions in the range of 30 MHz to 12.5 GHz are
more than 20 dB below the limit.

NOTE: The test data provided in this section is to support the requirement for
the digital apparatus.

2.15 Measurement Uncertainty

       The measurement uncertainties given were calculated using the method
detailed in CISPR 16-4-2: 2011. A coverage factor of k=2 was used to give a level
of confidence of approximately 95%.

2.15.1 Conducted Emissions Measurement Uncertainty

      Measurement Uncertainty (within a 95% confidence level) for this test is ±
2.85 dB.

       This EUT is battery powered; therefore this tested was deemed not
applicable.

2.15.2 Radiated Emissions Measurement Uncertainty

        For a measurement distance of 3 m the measurement uncertainty (with a
95% confidence level) for this test using a Biconical Antenna (30 MHz to 200 MHz)
is ± 5.40 dB. This value includes all elements of measurement.

      The measurement uncertainty (with a 95% confidence level) for this test using
a Log Periodic Antenna (200 MHz to 1000 MHz) is ± 5.19 dB.

The measurement uncertainty (with a 95% confidence level) for this test using a
Horn Antenna is ± 5.08 dB.

       The data listed in this test report does have sufficient margin to negate the
effects of uncertainty. Therefore, the EUT unconditionally meets this requirement.
