RF EXPOSURE EVALUATION 1. PRODUCTINFORMATION Product Description Mavenir Dual-band B25B66 RRU Model Name MR44MOA FCC ID 2AWAS-901-00094 2. EVALUATION METHOD AND LIMIT 3. ASSESSMENT RESULT Frequency (MHz) Maximum EIRP (dBm) Maximum EIRP [mW] Distance [cm] Power Density = 1mW/cm2 Proposed Minimum RF Safety Distance [cm] 2120 MHz ~ 2180 MHz (LTE Band 66) (Ant1+2+3+4) 57.55 568852.93 212.76 212 Note: 1) Maximum turn-up output power is 46dBm per each port declared by the manufacturer. 2) The distance [cm] is calculated according to the Friis formula: D = SQRT (EIRP / (4π * S)), Where S = power density in mW/cm2 EIRP = Effective Isotropic ally Radiated Power in mW EIRP = Antenna Port Conducted Power (45.96dBm) + Antenna Gain (18.4 dBi) = 64.36dBm Calculated distance: D = SQRT (EIRP / (4π * S)) D =√45267.771÷ (4π*1)= 212.76 cm 3) Only the worst case recorded. 4. CONCLUSION The device complies with the FCC RF exposure requirements with minimum RF safety distance of 212cm for General Population / Uncontrolled Exposure
