MACKARL ENTERPRISES INC. FCC ID: NK631238 Report #: RSZ10030401-Base Page 10 of 51 FCC Part 15D Test Report FCC §15.319 (i) - RF RADIATION EXPOSURE Limit According to §1.1307(b)(1), systems operating under the provisions of this section shall be operated in a manner that ensures that the public is not exposed to radio frequency energy level in excess of the Commission’s guidelines. According to §1.1310 and §2.1091 RF exposure is calculated. Limits for Maximum Permissible Exposure (MPE) Frequency Range (MHz) Electric Field Strength (V/m) Magnetic Field Strength (A/m) Power Density (mW/cm 2 ) Averaging Time (minute) Limits for General Population/Uncontrolled Exposure 0.3-1.34 614 1.63 *(100) 30 1.34-30 842/f 2.19/f *(180/f\2\) 30 30-300 27.5 0.073 0.2 30 300-1500. / / f/1500 30 1500-100,000. / / 1.0 30 f = frequency in MHz * = Plane-wave equivalent power density Test Data Predication of MPE limit at a given distance, Equation is from OET Bulletin 65, Edition 97-01 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, the power gain factor, is normally numeric gain. R = distance to the center of radiation of the antenna (appropriate units, e.g., cm) Maximum peak output power at antenna input terminal: 18.65 (dBm ) Maximum peak output power at antenna input terminal: 73.28 (mW) Prediction distance: 20 (cm) Predication frequency: 1921.536 (MHz) Antenna Gain (typical): 0 (dBi) Antenna Gain (typical): 1 numeric The worst case is power density at predication frequency at 20 cm: 0.0146 (mW/cm 2 ) MPE limit for general population exposure at prediction frequency: 1 (mW/cm 2 ) Conclusion: The power density at 20 cm is less than the MPE limit.
