Certification Exhibit FCC ID: R7PEG1R1S6 FCC Rule Part: 15.247 ACS Project Number(s): 15-0242 Manufacturer: Landis+Gyr Technology, Inc. Model: G5 Integrated Focus AXe 5015 B.U. Bowman Drive Buford, GA 30518 USA Voice: 770-831-8048 Fax: 770-831-8598

Model: G5 Integrated Focus AX FCC ID: R7PEG1R1S6 General Information: Applicant: Landis+Gyr Technology, Inc. Device Category: Mobile Environment: General Population/Uncontrolled Exposure Required Separation Distance: 20 cm The 900 MHz frequency hopping spread spectrum radio is collocated and transmits simultaneously with the separate on-board Landis+Gyr direct sequence spread spectrum 2.4 GHz Zigbee radio. Technical Information: Table 1: Technical Information Landis+Gyr Landis+Gyr LAN radio Zigbee radio 900 MHz 2.4 GHz Antenna Type PIFA PIFA Antenna Gain 6 dBi 6 dBi Conducted Power 677.64 mW 68.23 mW Maximum EIRP 2697.74 mW 271.64 mW ACS Project: 15-0242 Advanced Compliance Solutions Page 2

Model: G5 Integrated Focus AX FCC ID: R7PEG1R1S6 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) Transmit Radio Power Density Radio Antenna Antenna Power Distance Frequency Power Limit Power Gain Gain (cm) Density Radio (MHz) (dBm) (mW/Cm2) (mW) (dBi) (mW eq.) (mW/cm^2) 902.2 28.31 0.60 677.64 6 3.981 20 0.537 A 2405 18.34 1.00 68.23 6 3.981 20 0.054 B Summation of MPE Ratios – Simultaneous Transmissions This device contains multiple transmitters which can operate simultaneously; therefore MPE compliance is determined by the summation of MPE ratios. The limit is such that the summation of MPE ratios is ≤ 1.0.
