LS Research, LLC s scope of accreditation includes all test methods listed herein, unless otherwise noted. 3.0 Client Information Manufacturer Name: Address: Contact Person: Laird Technologies W66 N220 Commerce Court Cedarburg, Wisconsin 53012 N. Zach Hogya 3.1 Equipment Under Test (EUT) Information The following information has been supplied by the applicant. Product Name: RM186-SM Model Number: Serial Number: RM186-SM LEN DVT 29 (Radiated) LEN DVT 20 (Conducted) 3.2 Product Description The RM186-SM module is designed to enable OEMs to add a long range LoRa radio link as well as central role Bluetooth Low Energy (BLE) to small, portable, power-conscious devices. The RM186-SM module is enabled with Laird s smart BASIC, an event-driven programming language that enables OEMs to make their product development quicker and simpler, significantly reducing time to market. smartbasic enables customers to develop a complete embedded application inside the compact RM191 hardware, connecting to a wide array of external sensors via its I2C, SPI, UART, ADC or GPIO interfaces. The module is based on the world-leading Nordic Semiconductor nrf51822 (BLE) and Semtech Sx1272 (LoRa) chipsets, the RM186-SM module provides ultra-low power consumption with outstanding wireless range using the LoRa radio link and local BLE connections. 3.3 Modifications Incorporated In the EUT for Compliance Purposes None noted at time of test 3.4 Deviations & Exclusions from Test Specifications None noted at time of test Page 5 of 34
3.5 Additional Information The EUT was used with UwTerminalX (v1.01), a software program designed to allow the module to be programmed into various test modes. For the testing, Radiotest firmware was used to control the channel and output power. Only the max power setting was used (+4 db). Channels used for testing range from 2402 2480 MHz. When referenced elsewhere: Low: 2402 MHz Mid: 2440 MHz High: 2480 MHz The BLE radio on the module utilizes an integral monolithic chip antenna with a peak gain of 0 dbi. 4.0 Conditions of Test Environmental: Temperature: 20-25º C Relative Humidity: 30-60% Atmospheric Pressure: 86-106 kpa Supply to EUT: 3.6 VDC Extreme Environmental: Temperature: -40 C to +85 C 5.0 Test Equipment All test equipment is calibrated by a calibration laboratory accredited to the requirements of ISO 17025. For a complete list of test equipment and calibration dates, see Appendix A. Unless otherwise noted, resolution bandwidth of measuring instrument used during testing for given frequency range, see below. Page 6 of 34
6.0 Conformance Summary The EUT was found to MEET the requirements as described within the specification of ETSI EN 300 328 v.1.9.1. If some emissions are seen to be within 3 db of their respective limits: As these levels are within the tolerances of the test equipment and site employed, there is a possibility that this unit, or a similar unit selected out of production may not meet the required limit specification if tested by another agency. LS Research, LLC certifies that the data contained herein was taken under conditions that meet or exceed the requirements of the test specifications. The results in this Test Report apply only to the item(s) tested on the above-specified dates. Any modifications made to the EUT subsequent to the indicated test date(s) will invalidate the data herein, and void this certification. Page 7 of 34

Appendix B General Description of Measurement B.1 RF Conducted measurements Test Location Standard General Description of Measurement LS Research, LLC ETSI EN 300 328 v.1.9.1 Appendix C A direct measurement of the transmitted signal was performed at the antenna port of the EUT via a cable connection to a spectrum analyzer. An attenuator was placed in series with the cable to protect the spectrum analyzer. The loss from the cable and the attenuator were added on the analyzer as gain offset settings there by allowing direct measurements, without the need for any further corrections. The EUT was configured to run in a continuous transmit mode, while being supplied with typical data as a modulation source. Page 10 of 34
B.2 Radiated Emissions Standard ETSI EN 300 328 v1.9.1 Annex B and Annex C Test Location LS Research, LLC - FCC Listed 3 meter Semi-Anechoic Chamber Test Distance 3 meter EUT Placement Frequency Range of Measurement Description of Radiated Measurement Description of Substitution Measurement Example Calculations 150 cm height non-conductive table above reference ground plane Biconical: 30-200 MHz Log Periodic Dipole Array: 200-1000 MHz Double-Ridged Waveguide Horn: 1-18 GHz 1) The antenna, cable, pre-amp, and other necessary measurement system correction factors are loaded onto the EMI receiver / spectrum analyzer when the measurements are performed. The data is gathered and reported as the corrected values. 2) The EUT is placed on a non-conductive pedestal centered on a turn-table in the test location with the antenna at the test distance from the EUT 3) Maximum radiated RF emissions are determined by rotation of azimuth and scanning the sense antenna between 1 and 4 meters in height using both horizontal and vertical antenna polarities. Maximized levels are manually noted at degree values of azimuth and at sense antenna height. 1) The EUT is replaced by an antenna of known gain connected to a calibrated signal source. 2) The antenna is oriented in the polarization of the receive antenna. 3) The frequency if the signal generator is adjusted to the measurement frequency. 4) The test antenna is raised and lowered to ensure maximum signal is received. 5) The input signal to the substitution antenna is adjusted in level until an equal or known related level to that detected from the transmitter is obtained in the test receiver. Or the equation EIRP [dbm] = E [dbµv/m] +20*log(D[meters]) - 104.77 was utilized. Reported Measurement data = Raw receiver measurement + Antenna Correction Factor + Cable factor (db) - amplification factor (when applicable) + Additional factor (when applicable) Page 11 of 34
