US Tech Test Report: FCC Part 15 Certification/ RSS 210 FCC ID: KE3-3002587-1 IC: 2721A-30025871 Test Report Number: 19-0099 Issue Date: April 19, 2019 Customer: Radio Systems Model: Boundary Plus Single Loop Transmitter 2.5 Measurement Detector Function and Bandwidth (CFR 15.35) The radiated and conducted emissions limits shown herein are based on the following: 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. 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. 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 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. Page 11 of 26

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. 2.8 Intentional Radiator, Power Line Conducted Emissions (CFR 15.207) Power line conducted emissions testing was performed to ensure that with the EUT in operation (exercising all transmitter functions), the complete system continues to meet the applicable requirements for CFR 15.207. Results are displayed along with the 15.107 power line test data in the sections below. 2.9 Intentional Radiator, Radiated Emissions (CFR 15.209, (IC RSS 210)) 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. For radiated emissions, any emission that was greater than 20 dB from the applicable limit was not recorded. If radiated emissions above 1 GHz were measured at a distance of 1 meter, the measured value at 1 meter was extrapolated to the results at 3 meters using an inverse distance extrapolation factor of -20 dB/decade. Results are displayed along with the 15.109 test data in the sections below. Page 13 of 26

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 emission in the range of 9 kHz to 1 GHz was 2.6 dB below the limit at 239.750 MHz. This signal is found in Table 8. All other radiated emissions were 3.6 dB or more below the limit. 2.13 Radiated Emission Limits - General Requirements (a) Except as provided elsewhere in this subpart, the emissions from an intentional radiator shall not exceed the field strength levels specified in the following table: Frequency (MHz) Field strength (microvolts/meter) Measurement distance (meters) 0.009-0.490 2400/F(kHz) 300 0.490-1.705 24000/F(kHz) 30 1.705-30.0 30 30 30-88 100** 3 88-216 150** 3 216-960 200** 3 Above 960 500 3 **Except as provided in paragraph (g), fundamental emissions from intentional radiators operating under this section shall not be located in the frequency bands 54-72 MHz, 76-88 MHz, 174-216 MHz or 470-806 MHz. However, operation within these frequency bands is permItted under other sections of this part, e.g., §§15.231 and 15.241. Fundamental Limit calculation: at 10.7 kHz = 2400/10.7 = 224.3 uV/m @ 300 m Conversion from uV/m to dBuV/m = 20 log 224.3 = 47.02 dBuV/m Conversion from 300 to 3 m = 40 log (300/3)= 80 Limit at 3 meter = 47.02 + 80 = 127.02 dBuV/m Page 19 of 26

A coverage factor of k=2 was used to give a level of confidence of approximately 95%. 2.14.1 Conducted Emissions Measurement Uncertainty Measurement Uncertainty (within a 95% confidence level) for this test is ± 2.85 dB. The data listed in this test report does not have sufficient margin to negate the effects of uncertainty. Therefore, the EUT conditionally meets this requirement. 2.14.2 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 data listed in this test report does not have sufficient margin to negate the effects of uncertainty. Therefore, the EUT conditionally meets this requirement. Page 26 of 26
