Mikrotik Model: RB931-2nD Test Number: 160414C MPE Calculator MPE uses EIRP for calculation. EIRP is based on TX power added to the antenna gain in dBi. dBi = dB gain compared to an isotropic radiator. S = power density in mW/cm^2 Antenna Gain (dBi) 2.7 Output Power dBd + 2.17 = dBi dBi to dBd 2.2 Tx Frequency (MHz) 2437 Maximum (Watts) 0.097778 Antenna Gain (dBd) 0.53 Cable Loss (dB) 0.0 (dBm) 19.9 Antenna minus cable (dBi) 2.70 Calculated ERP (mw) 110.470 EIRP = Po(dBM) + Gain (dB) Calculated EIRP (mw) 182.072 Radiated (EIRP) dBm 22.602 Power density (S) ERP = EIRP - 2.17 dB Radiated (ERP) dBm 20.432 EIRP ------- = mW/cm^2 4 p r^2 EIRP (mW), r (cm) Occupational Limit FCC radio frequency radiation exposure limits per 1.1310 5 mW/cm2 Frequency (MHz) Occupational Limit (mW/cm2 ) Public Limit (mW/cm2 ) 50 W/m2 300-1,500 f/300 f/1500 General Public Limit 1,500-10,000 5 1 1 mW/cm2 10 W/m2 Occupational Limit IC radio frequency radiation exposure limits per RSS-102 0.6455ƒ0.5 W/m2 Frequency (MHz) Occupational Limit (W/m2 ) Public Limit (W/m2 ) 0.95332 W/m2 100-6,000 0.6455ƒ0.5 General Public Limit 6,000-15,000 50 0.02619ƒ0.6834 W/m2 48-300 1.291 2 0.6834 5.40397 W/m 300-6,000 0.02619ƒ 6,000-15,000 50 10 EIRP S S Distance Distance Distance Distance milliwatts mW/cm2 W/m2 cm meter inches Feet 182.072 0.00179 0.01789 90.00 0.90 35.43 2.95 182.072 0.00226 0.02264 80.00 0.80 31.50 2.62 182.072 0.00296 0.02957 70.00 0.70 27.56 2.30 182.072 0.00402 0.04025 60.00 0.60 23.62 1.97 182.072 0.00580 0.05796 50.00 0.50 19.69 1.64 182.072 0.00906 0.09056 40.00 0.40 15.75 1.31 182.072 0.01610 0.16099 30.00 0.30 11.81 0.98 182.072 0.03622 0.36222 20.00 0.20 7.87 0.66 182.072 0.09273 0.92728 12.50 0.13 4.92 0.41 182.072 0.22639 2.26388 8.00 0.08 3.15 0.26 182.072 0.40247 4.02467 6.00 0.060 2.36 0.20 182.072 0.49687 4.96873 5.40 0.054 2.13 0.18 182.072 0.57955 5.79553 5.00 0.050 1.97 0.16 182.072 0.95259 9.52586 3.90 0.039 1.54 0.13 182.072 1.60987 16.09870 3.00 0.030 1.18 0.10 182.072 4.47186 44.71860 1.80 0.018 0.71 0.06 182.072 14.48883 144.88826 1.00 0.010 0.39 0.03 Occupational Limit minimum Distance Frequency (MHz) Public Limit minimum distance (meters) (meters) 47CFR 1.1310 0.20 0.20 RSS-102 0.20 0.20 Rogers Labs, Inc.
