Model: M2 Gateway FCC ID: SK9M2LG1 IC: 864G-M2LG1 1 GENERAL 1.1 Purpose The purpose of this report is to demonstrate compliance with Part 15 Subpart C of the FCC’s Code of Federal Regulations and Industry Canada’s Radio Standards Specification RSS-210 for Certification of a single limited modular approval. 1.2 Product description The M2 Gateway module is a utility meter register board designed to be integrated into a variety of electric meter form factors. The M2 GATEWAY contains (1) 900 MHz LAN frequency hopping spread spectrum radio and (1) 2.4 GHz direct sequence spread spectrum Zigbee radio. Manufacturer Information: Itron Electricity Metering, Inc. 2111 N. Molter Rd. Liberty Lake, WA 99019 Test Sample Serial Number(s): 300490690 Test Sample Condition: The test samples were provided in good working order with no visible defects. 1.3 Test Methodology and Considerations This M2 Gateway is a composite device by definition. The 900 MHz LAN radio and the 2.4 GHz Zigbee radio operate under CFR 47 Part 15.247 and IC RSS-210. This report addresses the 2.4 GHz Zigbee radio only. A separate report will be issued to address the 900 MHz LAN radio. The M2 Gateway was integrated into a 2S meter form for AC power line conducted emissions and radiated emissions. The 2S meter form is representative of a typical host device. Both the 900 MHz LAN radio and the 2.4 GHz Zigbee radio can transmit simultaneously therefore radiated inter-modulation products were evaluated and found to be in compliance. For the purpose of RF conducted measurements, the M2 GATEWAY module was modified with a temporary 50 ohm antenna port. ACS Report: 10-0260.W06.22.A Advanced Compliance Solutions Page 3

All antenna types were evaluated. Because the upper band-edge coincides with a restricted band, band-edge compliance for the upper band-edge was determined based on absolute radiated field strength measurements. The lower band-edge compliance was determined using the conducted marker-delta method in which the radio frequency power that is produced by the EUT is at least 20 dB below that in the 100 kHz bandwidth within the band that contains the highest level of desired power. 7.6.1.2 Measurement Results Band-edge data is displayed in Table 7.6.1.2-1 and Figure 7.6.1.2-1.

Model: M2 Gateway FCC ID: SK9M2LG1 IC: 864G-M2LG1 7.6.3 Radiated Spurious Emissions (Restricted Bands) - FCC Sec. 15.205 IC: RSS-210 2.6 7.6.3.1 Measurement Procedure Radiated emissions tests were made over the frequency range of 30MHz to 25 GHz, 10 times the highest fundamental frequency. The EUT was rotated through 360° and the receive antenna height was varied from 1m to 4m so that the maximum radiated emissions level would be detected. For frequencies below 1000MHz, quasi-peak measurements were made using a resolution bandwidth RBW of 120 kHz and a video bandwidth VBW of 300 kHz. For frequencies above 1000MHz, peak and average measurements were made with RBW and VBW of 1 MHz and 3 MHz respectively. The average emissions were further corrected by applying the duty cycle correction of the EUT for comparison to the average limit. Each emission found to be in a restricted band as defined by section 15.205 was compared to the radiated emission limits as defined in section 15.209. 7.6.3.2 Duty Cycle Correction The device operates with a 27% duty cycle, therefore for average radiated measurements the measured level was reduced by a factor 11.37dB. The duty cycle correction factor is determined using the formula: 20log (27/100) = -11.37dB. A detailed analysis of the duty cycle timing is provided in the Theory of Operation accompanying this report. ACS Report: 10-0260.W06.22.A Advanced Compliance Solutions Page 19
