Model: FLEXLG100 FCC ID: SDBFLEXLG100 IC: 2220A-FLEXLG100 General Information: Applicant: Sensus Metering Systems, Inc. ACS Project: 08-0432-LD FCC ID: SDBFLEXLG100 Device Category: Mobile Environment: Uncontrolled/General Population Technical Information: Antenna Type: PCB Printed Monopole Antenna Gain: 0dBi Maximum Transmitter Conducted Power: 29.52dBm Maximum System EIRP: 29.52dBm, 0.895 W Exposure Conditions: Greater than 20 centimeters 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 Power Distance Frequency Power Density Limit Power Gain Gain Density (cm) (MHz) (dBm) (mW/Cm2) (mW) (dBi) (mW eq.)
