Page 6 of 8 Report No.: OT-19O-RWD-042 4. MAXIMUM PERMISSIBLE EXPOSURE 4.1 RF Exposure Calculation According to the FCC rule 1.1310 table 1B, the limit for the maximum permissible RF exposure for an uncontrolled environment are f/1500 mW/cm² for the frequency range between 300 MHz and 1 500 MHz and 1.0 mW/cm² for the frequency range between 1 500 MHz and 100 000 MHz. The electric field generated for a 1 mW/cm² exposure is calculated as follows: E = √ (30 * P * G) / d, and S = E² / Z = E² / 377, because 1 mW/cm² = 10 W/m² Where S = Power density in mW/cm², Z = Impedance of free space, 377 Ω E = Electric filed strength in V/m, G = Numeric antenna gain, and d = distance in meter Combing equations and rearranging the terms to express the distance as a function of the remaining variable d = √ (30 * P * G) / (377 *10 S) Changing to units of mW and cm, using P (mW) = P (W) / 1 000, d (cm) = 0.01 * d (m) d = 0.282 * √ (P * G) / S Where d = distance in cm, P = Power in mW, G = Numeric antenna gain, and S = Power density in mW/cm² Kind of EUT NOVO □ Portable (< 20 cm separation) Device Category □ Mobile (> 20 cm separation) ■ Others ■ MPE Exposure □ SAR Evaluation Applied □ N/A Tested by: Hyung-Kwon, Oh / Assistant Manager It should not be reproduced except in full, without the written approval of ONETECH Corp.
