Model: G5 26-1905 FCC ID: R7PEG1R1S5 IC: 5294A-EG1R1S5 General Information: Applicant: Landis+Gyr Technology, Inc. Environment: General Population/Uncontrolled Exposure Exposure Conditions: Mobile Technical Information – 900MHz Gridstream Radio: Antenna Type: Inverted F Antenna Gain: 3dBi Maximum Transmitter Conducted Power: 29.63 dBm, 918.33 mW Maximum System EIRP: 32.63 dBm, 1832.32 mW Technical Information – Zigbee Radio: Antenna Type: Inverted F Antenna Gain: 5dBi Maximum Transmitter Conducted Power: 20.71 dBm, 117.76 mW Maximum System EIRP: 25.71 dBm, 372.39 mW 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) MPE Calculator for Mobile Equipment Limits for General Population/Uncontrolled Exposure Transmit Radio Power Radio Antenna Antenna Distance Power Density Frequency Power Density Limit Power Gain Gain (mW (cm) (mW/cm^2) (MHz) (dBm) (mW/Cm2) (mW) (dBi) eq.) 902.2 29.63 0.60 918.33 3 1.995 20 0.365 2405 20.71 1.00 117.76 5 3.162 20 0.074 Summation of Power Densities – 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. The summation of MPE ratios is as follows: 900 LAN MPE Ratio + Zigbee MPE Ratio (0.365 / 0.60) + (0.074 / 1.0) = (0.608) + (0.074) = 0.682 0.682 < 1 RF Exposure In accordance with FCC requirements of human exposure to radio frequency fields, the radiating element shall be installed such that a minimum separation distance of 20 centimeters will be maintained. Conclusion This device complies with the MPE requirements by providing adequate separation between the device, any radiating structure and the general population.
