FCC ID: A28ISURF1000A1 Page 1 of 2 Prediction of MPE limit at given distance Product Description: WIFI VOIP Gateway Type: iSurf 1000 1. Introduction Equation from page 18 of OET Bulletin 65, Edition 97-01 Where: S = power density P = power input to the antenna 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 2. Limits for Maximum Permissible Exposure According to FCC Part 1.1307, systems operating under the provisions of this section shall be operated in a manner the ensures that the public is not exposed to radio frequency energy level in excess of the commission’s guidelines. According to FCC Part 1.1310 RF exposure is calculated. Limits for General Population/ Uncontrolled Exposure Limits for General Population/ Uncontrolled Exposure Frequency Range (MHz) Electric Field Strength(E)(V/m) Magnetic Field Strength (H)(A/m) Power Density (S)(mW/cm 2 ) 0.3-1.34 614 1.63 (100)* 1.34-30 824/f 2.19/f (180/f2)* 30-300 27.5 0.073 0.2 300-1500 f/1500 1500-100,000 1.0 FCC ID: A28ISURF1000A1 Page 2 of 2 3. Test result Maximum peak output power at antenna input terminal(dBm): 16.81 Total Maximum peak output power at antenna input terminal(mW): 48.64 Prediction distance(cm): 20 Predication frequency(MHz): 2437 Antenna Gain (typical) (dBi): 3 Power density at predication frequency at 20 cm(mW/cm 2 ): 0.01 MPE limit for RF exposure at prediction frequency(mW/cm 2 ): 1 4. Conclusion The predicted power density level at 20cm is 0.01mw/cm 2 which is below the uncontrolled exposure limit of 1.0mw/cm2. The EUT is used at least 20cm away from user’s body. It is determined as mobile equipment and complied with the MPE limit.
