FCC Section 2.1046 - RF Power Output 2.1 RF Power Output This test is a measurement of the total RF power level transmitted at the antenna-transmitting terminal. The product was configured for test as shown in section 1.6 above and allowed to warm up and stabilize per KDB 971168 D01 and ANSI C63.26. Power measurements were made with an MXA signal analyzer in the average mode. Before the testing was started, the Base Station was given a sufficient “warm-up” period as required. NOTE: Only a sample of all the plots taken have been used in this report. The full suite of raw data resides at the MH, New Jersey location. 2.1.1 Peak-to-Average Power Ratio (PAPR) The Peak-to-Average Power Ratio (PAPR) was evaluated per KDB 971168 for 10MHz and 20MHz bandwidths with QPSK modulation for In Band and Guard Band. The PAPR values of all carriers measured are below 13dB. The maximum rated mean RF power outputs of the EUT at its antenna transmitting terminals is 5W (+37 dBm) per 10MHz and 20MHz LTE carrier per port and 10 W (+40 dBm) per MBO, within ±1dB derivation, and are in full compliance with the Rules of the Commission. 2.1.2 PAPR, 10MHz, QPSK – In Band NB IoT PUBLIC Page 9 of 24

FCC Section 2.1049 – Occupied Bandwidth 4.1 Occupied Bandwidth In 47CFR 2.1049 the FCC requires: “The occupied bandwidth, that is the frequency bandwidth such that, below its lower and above its upper frequency limits, the mean powers radiated are each equal to 0.5 percent of the total mean power radiated by a given emission shall be measured under the following conditions as applicable.” This required measurement is the 99% Occupied Bandwidth, also called the designated signal bandwidth and needs to be within the parameters of the products specified emissions designator. During these measurements it is customary to evaluate the Edge of Band emissions at block/band edges. The transmitted signal occupied bandwidth was measured using a Keysight MXA Signal Analyzer. All emissions were within the parameters as previously filed. Sample Charts are below.

FCC Test Report Global Product Compliance Laboratory Report No.: TR-2019-0015-FCC2-24 Product: FW2FMBOM1 RF Module 4.2 Occupied Bandwidth/ Edge of band Emissions The Edge of Band emissions of the EUT at the external antenna connector (EAC) were measured using a Keysight MXA Signal Analyzer. The RF power level was continuously measured using a RF broadband power meter. The RF output from the EAC port to spectrum analyzer was reduced (to an amplitude usable by the spectrum analyzer) by using a calibrated attenuator and test coupler. The path attenuation was offset on the display and the signal for single carrier was adjusted to the corrected RF power level for the resolution bandwidth used for the transmit signal. All mask values were adjusted based upon the designated signal bandwidth and measurement bandwidths. The Top of Mask corresponds to the set rated power level as confirmed by the RF power meter. 4.2.1 Edge of band Emissions. The Occupied Bandwidth was measured for QPSK modulation at each signal bandwidth. The mask on the plots meet the Block Edge requirements as specified in 47CFR 24.238. All of the measurements met the requirements of Part 24.238 when measured per Part 2.1049. NOTE: Only a sample of all the data taken have been used in this report.

FCC Section 2.1051 - Spurious Emissions at Transmit Antenna Port 5.1 Measurement of Spurious Emissions at Transmit Antenna Port Spurious Emissions at the transmit-antenna terminals were investigated over the frequency range of 10 MHz to beyond the 10th harmonic of the specific transmit band. For this band of operation, the measurements were performed up to 22GHz. Measurements were made using a Keysight MXA Signal Analyzer. The RF output from the transmitter was reduced (to an amplitude usable by the receivers) using calibrated attenuators. The RF power level was continuously monitored via a coupled RF Power Meter. The required emission limitation is specified as appropriate in 24.238. The measured spurious emission levels were plotted for the frequency range as specified in 2.1057. There were no reportable emissions. Data below documents performance up to 22 GHz. NOTE: Only a sample of all the data taken have been used in this report.

FCC Test Report Global Product Compliance Laboratory Report No.: TR-2019-0015-FCC2-24 Product: FW2FMBOM1 RF Module 6. FCC Section 2.1053 6.1 Section 2.1053 Field Strength of Spurious Emissions Field strength measurements of radiated spurious emissions were made in 3m Semi-Anechoic Chambers the of Global Product Compliance Laboratories of Nokia Bell Labs in Murray Hill NJ. A complete description and full measurement data for the site is on file with the Commission (FCC File 515091). The spectrum from 30 MHz to beyond the tenth harmonic of the carrier, 27 GHz, was searched for spurious radiation. Measurements were made using both horizontally and vertically polarized broadband antennas. Per FCC regulations, the comparison of out of band spurious emissions directly to the limit is appropriately made using the substitution method. However, when the emissions are more than 20 dB below the specification limit, the use of field strength measurements for compliance determination is acceptable and those emissions are considered not reportable (Section 2.1053 and the FCC Interpretive database for 2.1053). For this case the evaluation of acceptable radiated field strength is as follows. 6.2 Field Strength of Spurious Emissions - Limits Sections 2.1053 and 24.238 contain the requirements for the levels of spurious radiation as a function of the level of the unmodulated carrier. The reference level for the unmodulated carrier is calculated as the field produced by an ideal dipole excited by the transmitter output power according to the following relation taken from Reference Data for Radio Engineers, page 676, 4th edition, IT&T Corp. E= [(30*P)1/2]/R 20 log (E*106) – (43 + 10 log P) = 82.23 dBV/meter Where: E = Field Intensity in Volts/meter P = Transmitted Power in Watts R = Measurement distance in meters = 3 m The Part 24 Limit is 82.23 dBuV/m at 3m and 91.77 dBuV/m at 1m The Part 24 non-report level is 62.23 dBuV/m at 3m. The calculated emission levels were found by: Measured level (dBV) + Cable Loss(dB)+Antenna Factor(dB) = Field Strength (dBV/m) RESULTS: For compliance with 47CFR Parts 2 and 24, the field strength of any spurious radiation, measured at 3m, is required to be less than 82.23 dBV/meter (82.23 @ 3m). Emissions equal to or less than 62.23 dBV/meter at 3m are not reportable and may be verified using field strength measurements and broadband antennas. Over the out of band spectrum investigated from 30 MHz to beyond the tenth harmonic of the carrier (up to 27GHz), no reportable spurious emissions were detected. PUBLIC Page 23 of 24
