Certification Exhibit FCC ID: SK9ACT1 FCC Rule Part: 47 CFR Part 2.1091 Project Number: 72124754 Manufacturer: Itron, Inc. Model: ACT1 RF Exposure 5015 B.U. Bowman Drive Buford, GA 30518 USA Voice: 770-831-8048 Fax: 770-831-8598

Model: ACT1 FCC ID: SK9ACT1 General Information: Applicant: Itron, Inc. Device Category: Mobile Environment: General Population/Uncontrolled Exposure The 900MHz LAN radio is collocated and transmits simultaneously with the 2.4GHz WiFi radio. Technical Information: Table 1: Technical Information 900MHz LAN 2.4GHz WiFi Radio Radio Frequency Band(s) 902.4 - 927.6 2412 - 2462 (MHz) 1/4 Wave Antenna Type(s) Whip Antenna Embedded Slot Antenna Antenna Gain 3.0 2.5 (dBi) Conducted Power 23.39* 18.54 (dBm) Conducted Power 218.27 71.45 (mW) Maximum Peak EIRP 435.51 127.06 (mW) Maximum Peak ERP 265.46 77.45 (mW) * Includes insertion loss of the coupling patch and associated cable.

Model: ACT1 FCC ID: SK9ACT1 MPE Calculation: The Power Density (mW/cm2) is calculated as follows: PG S= 4R 2 Where: S = power density (in appropriate units, e.g. mW/cm2) P = power input to the antenna (in appropriate units, e.g., mW) G = power gain of the antenna in the direction of interest relative to an isotropic radiator R = distance to the center of radiation of the antenna (appropriate units, e.g., cm) Table 2: MPE Calculation (Including Collocated Devices) Power Antenna Transmit Radio Radio Antenna Power Density Gain Distance Frequency Power Limit Power Gain (mW (cm) Density Radio (MHz) (dBm) (mW) (dBi) (mW/cm^2) (mW/Cm2) eq.) 915.2 23.39* 0.61 218.27 3 1.995 20 0.087 A 2437 18.54 1.00 71.45 2.5 1.778 20 0.025 B * Includes insertion loss of the coupling patch and associated cable. Summation of MPE ratios – Simultaneous Transmissions This device contains multiple transmitters which can operate simultaneously; therefore the maximum RF exposure is determined by the summation of MPE ratios. The limit is such that the summation of MPE ratios is ≤ 1.0.
